ORGANIC VEGETABLE PEST CONTROLGrowing garden vegetables organically means that insect pest control must be approached a bit differently.  On a recent K-State Garden Hour webinar, Johnson County Extension horticulture agent Zac Hoppenstedt discussed the approaches to organic insect management that will provide the best results for gardeners.  Here, he goes over several of the basic principles.

Hoppenstedt 05-27

ASSORTED LAWN AND GARDEN INSECTSNot surprisingly, with the rapid warm-up in the weather, an array of insects have ramped up in home landscapes and gardens.  K-State horticultural entomologist Raymond Cloyd reports on several that he’s hearing about from homeowners and gardeners…especially concerning aphids on landscape ornamentals and various bugs on early vegetable garden plants. He offers control advice for each.

Cloyd 05-20

PLANTING VEGETABLE TRANSPLANTSNow is the time to purchase and plant warm-season vegetable transplants such as tomatoes, peppers, and cucumbers.  Transplanting is a simple process, but still must be done right to assure that those plants get off to a strong start…and this year, that includes protecting them from the seemingly relentless wind.  Riley County Extension horticulture agent Gregg Eyestone talks about all of that this week.

Eyestone 05-13

POISON IVY CONTROLIt’s a common invader in home landscapes, yet it often is difficult to distinguish from other comparatively harmless plants: poison ivy.  Because it’s so caustic to the touch for many people, getting rid of it is a priority.  K-State horticulturist Ward Upham discusses accurately identifying poison ivy and means of controlling it for good.

Upham 05-06

ORNAMENTAL FLOWER SELECTIONThe local nurseries and garden stores are booming with ornamental flower selections for home flower beds, borders and hanging baskets.  Not all annual flowers can handle Kansas’ weather extremes, and that’s why K-State Research and Extension evaluates flower cultivars for their hardiness as well as for their aesthetics. Sedgwick County Extension horticulture agent Matthew McKernan talks about some of the new flower types and about basic flower care.

McKernan 04-29

ASSORTED INSECT PESTSAs the weather warms up, insect activity outside the home and around the landscape starts to pick up.  K-State horticultural entomologist Raymond Cloyd is already getting calls from homeowners about various early pest problems. This week, he discusses how to deal with clover mites entering homes from the yard, Nantucket tip moths feeding on pines, and eastern tent caterpillar webbing up in landscape trees.

Cloyd 04-22

FRUIT PEST SPRAYINGHome fruit growers are advised to get the jump on possible pest problems with the appropriate spray treatments here in early spring.  This is particularly true with apples, as well as peaches, nectarines and apricots, provided that latter group isn’t hit with freeze damage first.  This week, K-State horticulturist Ward Upham addresses preventative fruit pest control.

Upham 04-15

PLANTING FOR POLLINATORSBees and other pollinators serve an essential role in the ecosystem.  In recent years, there’s been greater interest on the part of homeowners in attracting pollinators to their home landscape.  On the most recent K-State Garden Hour webinar, Central Kansas Extension District horticulture agent Jason Graves discussed this week’s topic: plant selection for attracting and harboring pollinators continuously.

Graves 04-08

RAISED BED GARDENINGHome flower and vegetable gardeners  interested in trying something different this season might want to try raised bed gardening.  Raised beds make for easy access to the growing plants for care and harvesting. Johnson County Extension horticulture agent Dennis Patton covers the basics of establishing a raised bed growing site in the home landscape.

Patton 04-01

CONTAINER GARDENING ADVICEFor those with only limited outdoor space to grow things, or for those who simply want to liven up certain locations in their landscape, container gardening is just the ticket. Johnson County Extension horticulture agent Dennis Patton goes over the basics of succeeding with container gardening…from growing medium selection to appropriate container size for good plant productivity.

Patton 03-25

MORE ON POTATO PLANTINGStep one in planting garden potatoes in the spring is preparing the seed pieces…splitting the seed potatoes and letting them cure.  Step two, then, is the planting itself.  And in the second part of this conversation with K-State horticulturist Ward Upham, he covers planting depth and spacing, and planting site management at and following potato plant emergence.

Upham 03-18

PLANTING GARDEN POTATOES (part 1)St. Patrick’s Day is the signal most home gardeners go by for planting their potatoes.  But the truth is, vegetable gardeners can successfully plant those spuds anytime between now and mid-spring.  That’s according to K-State horticulturist Ward Upham, who leads off a two-part discussion by looking this week at potato variety selection and seed piece preparation.

Upham 03-11

ORNAMENTAL FLOWER SELECTIONAn ornamental flower bed or border should complement the surrounding home landscape.  And that comes back to flower type selection and planning for an attractive arrangement.  This was the theme of the latest K-State Garden Hour webinar, presented by Lyon County Extension horticulture agent Travis Carmichael.  This week, he covers some of the tips presented in that session.

Carmichael 03-04

SELECTING LANDSCAPE ORNAMENTALSAs hints of spring start to show up, homeowners may be in the market for new woody ornamental plant material for their landscapes.  Before placing any tree or shrub orders or outright making a purchase, doing one’s homework is imperative, according to K-State ornamental horticulturist Jason Griffin.  The first order of business, as Griffin outlines, is to assure that the new tree or shrub is likely to endure whatever conditions it will encounter in its new location.

Griffin 02-25

READYING FOR ASPARAGUS PLANTINGFor you home gardeners, it’s not quite time to plant a new asparagus bed.  However, preparation for that planting should start right now, according to K-State horticulturist Ward Upham.  Asparagus establishment differs from most other perennial vegetable plantings.  This week, he goes over the basic pre-plant preparatory steps.

Upham 02-18

PRUNING FRUIT TREESTree structure means everything to home tree fruit production. That’s why Kansas State University horticulturist Ward Upham urges fruit growers to check their trees over right now for pruning needs. According to Upham, different fruit trees require different pruning approaches. He goes over the steps, in order, for successfully pruning fruit-bearing trees. 

Upham 02-11

SUCCEEDING WITH TRANSPLANT STARTSHome gardeners trying their hand at raising transplants from seed may be disappointed that there’s not been much in the way of germination yet.  That could be attributed to any of several things, according to Riley County Extension horticulture agent Gregg Eyestone.  He walks through some steps that will help assure a successful outcome with those transplant starts, as were shared in a recent K-State Garden Hour webinar session which can now be viewed online.

Eyestone 02-4

STARTING VEGETABLE TRANSPLANTS (part 2)Once a home gardener has committed to raising vegetable transplants from seed, success rests with following some basic ground rules, according to Johnson County Extension horticulture agent Dennis Patton.  Included in those are planting the seed in the proper growing medium, and carefully managing the plants’ exposure to light and temperature. 

Patton 01-28

STARTING VEGETABLE TRANSPLANTS (part 1)Don’t look now, vegetable gardeners, but another growing season is only two months away.  If you’d like to get the jump on your garden activity, starting early-planted vegetable transplants from seed is a project worth undertaking, according to Johnson County Extension horticulture agent Dennis Patton.  In the first of a two-part visit, he talks about getting started with those transplants, with particular emphasis on one of the very first crops to be transplanted: onions.

Patton 01-21

WINTER LANDSCAPE WATERINGFollowing an unusually dry winter, homeowners often find that winter desiccation has taken a toll of their landscape trees and shrubs.  And that could have been avoided with a timely watering in mid-winter.  In that it is quite dry now in this area, providing supplemental moisture to those woody ornamentals is important, according to K-State horticulturist Ward Upham. He talks about how much watering is required, and how to go about it.

Upham 01-14

CHOOSING VEGETABLE VARIETIESThe garden catalogs are out, which promote all sorts of vegetable varieties for home gardeners to include in their production this year.  On a recent K-State Garden Hour webinar, Sedgwick County Extension horticulture agent Rebecca McMahon covered some general principles of vegetable variety selection…including the considerations she brings up on this week’s program.

McMahon 01-07

CARING FOR AMARYLLISFor those who want to add some color to their house this winter, an amaryllis plant could make that happen. Knowing how to maintain the plant could allow for more and longer blooms throughout the year. K-State Research and Extension horticulturist Ward Upham discusses what an amaryllis is and how to take care of it throughout the year.

Upham 12-24

PROTECTING ORNAMENTAL PLANTSThose who planted new landscape ornamental trees and shrubs over the past year have been nurturing those along for several months.  If left unprotected, wildlife damage can set those plantings back. The best step, according to Riley County Extension horticulture agent Gregg Eyestone, is to establish a wintertime barrier around those ornamentals. He discusses some of the options to consider.

Eyestone 12-17

DORMANT LAWN SEEDINGThis time of year is the last good chance to seed cool season grasses. There are different methods of application that can be used to seed those grasses. K-State Research and Extension horticulturist Ward Upham shares his knowledge on why now is the time to finish seeding cool season grasses and how to do it.

Upham 12-10

HOLIDAY PLANT CAREPoinsettias are a standard feature of holiday décor for many homeowners. With a little simple care, Johnson County Extension horticulture agent Dennis Patton says they can last for a long while, even after the holidays. He discusses general house plant care principles to follow for the duration of the winter.

Patton 12-03

LATE BULB PLANTINGThis week’s edition is for the procrastinators who have yet to plant their spring-flowering bulbs this fall. Fear not, says Johnson County Extension horticulture agent Dennis Patton.  As long as the ground hasn’t frozen, those bulbs can still be planted successfully…as long as the standard guidelines for planting are followed. Patton goes over those, and offers advice on purchasing “clearance sale” bulbs for planting now.

Patton 11-26

DORMANT TREE OILSWith the colder weather now coming on, insects in lawns and gardening areas will be, for the most part, conspicuously absent.  But as the growing season is now over, K-State horticultural entomologist Raymond Cloyd has a couple of items to address:  keeping landscape insects from finding an overwintering spot in your home, and treating landscape and fruit trees with dormant oil insecticides for winter protection.

Cloyd 11-19

LATE FALL LAWN CAREHomeowners with cool-season lawns like fescue or bluegrass should take some time to tuck their lawns away for the forthcoming winter.  K-State horticulturist Ward Upham says this is an excellent time to fertilize that lawn while the ground remains unfrozen. Also, you can get on top of dandelions and other broadleaf weeds with a late-fall herbicide application.

Upham 11-12

WINTER LANDSCAPE ENHANCEMENTOn the final segment of this year’s K-State Garden Hour webinar series, Wyandotte County Extension horticulture agent Lynn Loughary (LAU-ree) promoted the idea of creating an appealing home landscape for the winter season…when the weather tends to make everything look drab. She urges homeowners to seek out plant material that can add color and texture to the yard, even on the harshest winter days.

Loughary 11-05

LATE-SEASON LANDSCAPE BUGSInsect activity in home landscapes will largely grind to a halt soon. Still, there’s at least one pest that may deserve attention.  K-State horticultural entomologist Raymond Cloyd says that’s the spider mite, which is showing up on some landscape spruce trees and other conifers. He talks about dealing with that, and about the value of a general clean-up around the lawn and garden as a preventative measure against insect troubles next year.

Cloyd 10-29

LANDSCAPE TREE PLANTING (PART 2)Proper species selection and site preparation are the initial steps to planting a new landscape tree, and the fall is an ideal time to do so, according to a K-State forester.  Continuing his look at succeeding with tree planting, Charlie Barden addresses the next considerations: condition of the root ball before planting, placement of that root ball in the hole and backfilling around it, and staking the tree for stability.

Barden 10-22

FALL TREE PLANTING (PART 1)Fall makes for an excellent opportunity to add new ornamental trees to the home landscape. In fact, it’s the preferred time for tree planting, according to K-State forester Charlie Barden. In the first of a two-part series, he discusses the steps to succeeding with fall tree planting…starting with species selection and planting site preparation.

Barden 10-15

SUDDEN CEDAR LOSSMany homeowners in Kansas have been stunned this year by what appears to be a sudden demise of their landscape Atlas cedar trees…often resulting in the loss of the tree.  K-State horticulturist Ward Upham says the explanation is pretty simple...it's the result of a highly-unusual weather event that took place nearly a year ago. He discusses whether any of these damaged cedars that haven’t died out yet can be recovered.

Upham 10-08

LANDSCAPE BIRD HABITATFall is here and many homeowners are becoming more interested in attracting colorful songbirds to the home landscape.  As a trained ornithologist, Geary County Extension agricultural agent Chuck Otte is very much an expert on this. He goes over the principles of backyard bird feeding and habitat development, saying that by putting in a little effort, homeowners can make their landscape a haven for a wide assortment of birds.

Otte 10-01

PLANTING SPRING BULBSFall is officially here, and homeowners looking to add spring color to their landscapes should consider planting spring-flowering bulbs now.  As with any other landscape planting, K-State horticulturist Ward Upham says establishing those bulbs well is the secret to success with those spring blooms. He walks through the checklist for bulb planting and early management.

Upham 09-24

ARMYWORMS AND MOREThe onslaught of armyworms in lawns this summer has been alarming to many homeowners. K-State horticultural entomologist Raymond Cloyd talks about a potential second generation of armyworms showing up this fall. He also touches upon some other insects now appearing in landscape ornamental trees and whether homeowners should worry about them.

Cloyd 09-17

COMPOSTING WITH WORMSThere’s a novel approach to creating compost material for home gardening. It’s called vermicomposting…and it can be conducted indoors during all seasons of the year. This is a composting method using worms. Harvey County Extension horticulture agent Scott Eckert says not just any worms will do.

Eckert 09-10

FALL LAWN SEEDINGThe weather is gradually starting to turn…meaning the opportunity to seed, or overseed, a cool-season lawn is nearly at hand.  This project requires attention to detail in order to succeed, according to horticulturist Ward Upham of Kansas State University. He goes over the basics:  site preparation, seeding rates, fertilizer applications and, of course, watering.

Upham 09-03

HOME BERRY PRODUCTIONIt requires extra dedication to management, but garden berry crops can be successfully grown in Kansas.  That was emphasized in a recent K-State Garden Hour webinar by Sedgwick County Extension horticulture agent Rebecca McMahon. She goes over some of the primary things for home gardeners to think about.

McMahon 08-27

LANDSCAPE INSECT REPORTThere’s plenty of summer yet to go…meaning that landscape insects will remain prolific for quite a while yet.  The good thing, according to K-State horticultural entomologist Raymond Cloyd, is that the vast majority of these pests don’t warrant an insecticide treatment.  He highlights three such insects that fit into that category: green June beetles, fall webworms and cicada killers.

Cloyd 08-20

ENCOURAGING BENEFICIAL INSECTSMany homeowners and gardeners put time and effort into controlling damaging insects on their landscape ornamentals and garden vegetables. Reno County Extension horticulture agent Pam Paulsen says they often overlook the potential benefits of having beneficial predatory insects around to provide natural control.

Paulsen 08-13

TIPS FOR DIVIDING IRISIn this week’s lawn and garden segment, K-State horticulturist Ward Upham discusses how to divide iris...something that can be done now. The process involves cutting the rhizomes apart, inspecting the plant for soft rot or other damage, cutting back the leaves, and preparing the soil for new plantings.

Upham 08-06

ORGANIC GARDENING BASICSThe topic of organic home gardening was featured recently in the K-State Garden Hour webinar series. According to the presenter of that webinar, Zac Hoppenstedt, an Extension horticulture agent in Johnson County, organic gardening is really no more than adhering to some basic management principles. 

Hoppenstedt 07-30

HORTICULTURE DISEASE RESPONSEHot and humid weather often prompts an outbreak of diseases on ornamental and garden vegetable plants.  Fungicide treatments can do only so much, according to Riley County Extension horticulture agent Gregg Eyestone.  Good plant maintenance is often the best defense against common pathogens, and he offers some general advice along that line.

Eyestone 07-23

LANDSCAPE BUG UPDATEIt wouldn’t be mid-summer if there wasn’t a wide assortment of insects active in home landscapes right now. K-State horticultural entomologist Raymond Cloyd discusses a trio of species homeowners might be seeing in large numbers now:  Japanese and green June beetles and white flies. He talks about what should, or shouldn’t, be done about these.

Cloyd 07-16

VEGETABLE FRUIT SET– We’re well into the vegetable gardening season now, and some gardeners are concerned that their plants aren’t setting fruit like they should be at this point.  This could be for any of several reasons, according to K-State horticulturist Ward Upham, and it’s happening primarily on cucurbit and tomato crops.  He talks about the problem and what, if anything, gardeners should do about it.

Upham 07-09

DODGING TOMATO PROBLEMSThe tomato gardening season is well underway, and it's about this time that some tomato plant issues tend to turn up...such as slow fruit set, leaf curling and foliage diseases.  Johnson County Extension horticulture agent Dennis Patton address all of those conditions, and what gardeners can do, if anything, to counteract them.

Patton 07-02

HARVESTING ONIONS AND POTATOESFor home gardeners who planted potatoes and onions in mid-spring, harvest time is here, or at least nearly so.  This week, K-State horticulturist Ward Upham offers several tips on harvesting each for maximum quality, along with storage recommendations for preserving potato and onion quality prior to use.

Upham 06-25

BAGWORMS AND MOSQUITOSTwo of the most prominent summer landscape insect pests are now going hard at it: bagworms on ornamental evergreens, and mosquitos, seemingly everywhere.  K-State horticultural entomologist Raymond Cloyd talks about deterring both of these pests…one with timely treatments, the other by self-protection.

Cloyd 06-18

POLLINATOR-FRIENDLY LANDSCAPINGBees and other pollinators are essential contributors to our ecosystem.  And landscaping with pollinators in mind was the topic of a recent K-State Garden Hour webinar presented by Central Kansas Extension District horticulture agent Jason Graves. He shares some of the key principles of attracting pollinators to the home setting.

Graves 06-11

WATER USE EFFICIENCYThe warmer weather of summer is coming on, and attention is turning to the lawn, garden and landscape watering routines. Too often, people tend to overwater plants, or otherwise water in a less-than-efficient way. Riley County Extension horticulture agent Gregg Eyestone offers some general guidelines on watering that apply in most circumstances.

Eyestone 06-04

EVERGREEN BAGWORM CONTROLIt’s that time of the year again…the time when bagworms begin feeding on landscape ornamental trees and shrubs.  While they can turn up on a variety of plant material, they’re most threatening to landscape evergreens.  For good control, forest health specialist Ryan Armbrust of the Kansas Forest Service at K-State, says homeowners need to make a concerted effort to knock bagworms down.

Armbrust 05-28

SALVAGING FLOODED GARDENSSubstantial rainfall around Kansas in recent days has led to minor…and on occasion, not so minor…flooding in home vegetable gardens.  Likewise, storm damage may have left emerged vegetables looking a bit ragged.  K-State horticulturist Ward Upham says that if the damage isn’t too severe, most vegetables can recover. He offers some post-storm management guidance.

Upham 05-21

PRINCIPLES OF XERISCAPINGThough the idea has been around for quite a while, a lot of homeowners still aren’t familiar with it.  It’s called “xeriscaping”…developing a landscape featuring plant material which requires little water to survive and thrive during the growing season.  Horticulturists at Kansas State University have identified trees, shrubs and other ornamentals that can serve this purpose in an attractive way.  Shawnee County Extension horticulture agent Ariel Whitely Noll talks about the concept.

Whitely-Noll 05-14

LANDSCAPE INSECT ACTIVITYThe weather is slowly but surely warming up, prompting a variety of landscape insects to assert themselves right now.  K-State horticultural entomologist Raymond Cloyd reports this week on a trio of pests that homeowners should be on the lookout for, and what to do about them:  pine needle scale, lilac ash borers and elm flea weevils.

Cloyd 05-07

HOME HERB GARDENINGOne doesn’t have to be a master gardener to succeed with home-grown herbs.  That’s according to K-State horticulture agent Cassie Homan of the Post Rock Extension District.  In general, herbs are simple to grow and maintain, and can provide fresh material for home cooking. She says they can also serve the dual purpose of adding color and texture to the home landscape, if one is so inclined.

Homan 04-30

APRIL FREEZE IMPACTSIt was by no means unprecedented, but it surely left its mark on a lot of home gardens…that hard April freeze a few days back.  The question on gardeners’ minds:  which plant material survived and will it still be productive this growing season, and which won’t?  K-State horticulturist Ward Upham offers a quick rundown on several popular vegetable and fruit crops and their sensitivity to the recent cold temperatures.

Upham 04-23

SHADE GARDENING IDEASWhen it comes to ornamental gardening in the home landscape, those shady areas often go untouched, for fear that there’s not enough sunlight to support ornamental plant growth.  Johnson County Extension horticulture agent Dennis Patton sees that differently.  He says that shade gardening offers an opportunity to add color and texture to an under-utilized area of the landscape.

Patton 04-16

EARLY LANDSCAPE PESTSWarmer spring weather has taken over, cueing any number of insect pests to resume their activity.  K-State horticultural entomologist Raymond Cloyd has his eye on several current insect threats to landscape ornamental trees and shrubs, including pine sawflies, spruce spider mites and lilac/ash borers.

Cloyd 04-09

RAISED BEDS AND CONTAINERSIf you don’t have space for a traditional home garden or can’t have a garden where you live, K-State Research and Extension horticulture agent for Lyon County, Travis Carmichael, says raised bed or container gardening is a good alternative. He covers the basics of raised bed and container gardening.

Carmichael 04-02

EARLY LAWN CARECool-season lawns are greening up quickly now.  It’s time for homeowners to take up their lawn care program…and early on, that largely revolves around fertilization and weed control.  Anymore, those can be accomplished with a single product application.  However, Johnson County Extension horticulture agent Dennis Pattonsays you needsto be careful not to over-fertilize in the process.

Patton 03-26

LANDSCAPE TREE PLANTINGA new landscape tree is a healthy investment…therefore, planting it correctly is essential. Take the time to prepare the planting site, and follow a series of steps when placing the tree in its new home. K-State horticulturist Ward Upham covers the steps to successfully planting trees.

Upham 03-19

LANDSCAPE PRUNING TIPSPruning ornamental trees and shrubs should be a standard home landscape management practice.  And it’s one that should be done correctly, as emphasized in a recent online K-State Garden Hour workshop with Sedgwick County Extension horticulture agent Matthew McKernan.  He shares some of the pruning basics homeowners should employ approaching springtime.

McKernan 03-12

VEGETABLE GARDEN PREPThe weather is turning, and spring is essentially upon us. It’ll be time to plant those earliest vegetables of the gardening season quite soon. Is your gardening area fully prepped for those first plantings? K-State horticulturist Ward Upham discusses a few things to take care of ahead of planting.

Upham 03-05

HOME LANDSCAPING POINTERSDuring a recent K-State Garden Hour seminar, an Extension horticulture agent based in western Kansas offered basic guidelines for homeowners who are trying their hand at landscaping their property for the first time.  And one of the bedrocks for landscaping success is appropriate plant selection. Anthony Reardon talks about how critical that is, noting that there are abundant sources of information on plant material available.

Reardon 02-26

K-STATE’S GARDEN HOURInspired by the popularity of a series of webinars conducted last year, K-State Research and Extension horticulturists from all around the state are teaming up this year for a regular series of information webinars for homeowners and gardeners.  It’s called K-State’s Garden Hour…noontime sessions throughout the spring, summer and fall, covering timely topics in vegetable and fruit gardening, ornamental landscaping and other areas of interest.  K-State nursery crops horticulturist Cheryl Boyer has more.

Boyer 02-19

PRUNING FRUIT TREESOnce the weather allows, home fruit growers are advised to inspect their fruiting trees, and identify branches that should be pruned out before the growing season begins.  Annual pruning is standard practice for fruit trees, according to Riley County Extension horticultural agent Gregg Eyestone. He goes over how to make good pruning decisions and why pruning is important.

Eyestone 02-12

FARMERS MARKET WORKSHOPSK-State Research and Extension is once again teaming up with the Kansas Department of Agriculture to put on a series of Farmers Market Workshops.  This year, those will be conducted virtually from February 16th through the 19th.  Anyone who sells, or is looking to sell, home-grown produce at a farmers’ market is encouraged to take part. K-State food safety specialist Londa Nwadike is one of the workshop coordinators.

Nwadike 02-05

TREES AND GRASSThinking about planting a new landscape tree this spring?  One of the factors to consider is the potential for the surrounding grass to compete with that young tree for water and nutrients.  A Kansas State University study actually measured the impact of that competition on tree growth.  K-State horticulturist Ward Upham shares the findings of that research.

Upham 01-29

ALL-AMERICA ORNAMENTAL FLOWERSThe All-America Selections program has just announced its recommended new ornamental flowers for 2021.  The list isn’t all that long, but it builds upon a slew of ornamental plants that were similarly selected in recent years. K-State nursery crops horticulturist Cheryl Boyer talks about these new options which are all well-suited to growing conditions throughout Kansas.

Boyer 01-22

ALL-AMERICA VEGETABLESHere’s information for you home vegetable gardeners who are now lining out your gardening plans for this next growing season.   The All-America Selections program has just announced the latest additions to its vegetable lineup.  And Johnson County Extension horticulture agent Dennis Patton encourages gardeners to give these a look as candidates for planting.

Patton 01-15

STARTING VEGETABLE TRANSPLANTS – There’s a lot of winter yet to go, but vegetable gardeners can get a start on the next growing season by growing their own transplants.  It’s still too early to plant those seeds, but K-State horticulturist Ward Upham says you can be shopping for quality seed and setting up the special lighting required for germinating the transplants.

Upham 01-08

LIVE CHRISTMAS TREE– For those who elected to celebrate the holiday with a live Christmas tree, to be planted in the home landscape afterward, here’s some advice on succeeding with that.  Riley County Extension horticulture agent Gregg Eyestone says allowing that tree to adjust to the outdoor environment before planting is important…as is preparing the planting site beforehand. 

Eyestone 12-18

PROTECTING ORNAMENTAL TREES– As the cold of winter settles in for the long haul, rabbits, mice and other rodents start looking for additional food sources.  And tender young ornamental trees and shrubs are often on their menu.  By taking simple measures, Johnson County Extension horticulture agent Dennis Patton says you can protect vulnerable ornamentals from those hungry rodents.

 Patton 12-11

DORMANT LAWN SEEDING– Normally, winter is not an ideal time to plant cool-season lawn grass.  However, if you have one or more bare spots in your lawn, dormant seeding now can take care of those once spring green-up begins. And according to K-State horticulturist Ward Upham, spot-seeding is fairly easy to achieve.

Upham 12-04 

HOUSE PLANT CARE– When house plants are brought indoors for the winter, the transition can be a shock to a plant’s system…unless you take a few simple steps. K-State horticulturist Ward Upham talks about helping plants adjust to the change in light exposure and routine indoor plant care.

Upham 11-20 

NEW LANDSCAPE ORNAMENTALS – About this time of year, homeowners start turning their attention to the next growing season, and what’s new in landscape perennial plants. K-State nursery crops specialist Cheryl Boyer stays on top of the latest arrivals at local nurseries. She says there are several ornamentals which will likely do well in this region that have caught her attention.  

Boyer 11-13

DORMANT OIL APPLICATIONS– Lawn and garden insect management becomes of much lesser concern as colder weather comes on.  There is one thing that homeowners might look into right now…whether or not some of their landscape fruit or ornamental trees are infested with scale.  If so, a dormant oil treatment may be worthwhile. K-State horticultural entomologist Raymond Cloyd covers that and a false alarm that’s getting around about a highly-publicized insect pest.

Cloyd 11-06 

ATTRACTING BACKYARD BIRDS– The weather is definitely trending colder, and songbirds are looking for a safe haven for the winter. That could be your back yard if you provide well-placed bird feeders and waterers. Geary County Extension agricultural agent Chuck Otte, an accredited ornithologist, offers several guidelines for attracting birds to the home setting this winter.

Otte 10-30

SPRING-FLOWERING BULBS– If you have spring-flowering bulbs, it’s not too late to plant them. However, the window for planting is starting to narrow. K-State Research and Extension horticulturist Ward Upham says hardy bulbs, especially daffodils, should be planted in October or early November so they have time to root before winter.

Upham 10-23 

FALL LANDSCAPE PRUNING– These comfortable fall days encourage homeowners to get out and take on outdoor projects, like pruning landscape trees and shrubs.  Before getting the loppers or pruning saw out, consider the advice from Johnson County Extension horticulture agent Dennis Patton.  He says the timing of pruning is important and there are consequences for pruning at the wrong time.

Patton 10-16 

INSECT MIGRATION INDOORS– As the weather is steadily cooling off, landscape insects are taking their seasonal cue, and trying to find sanctuary indoors. K-State horticultural entomologist Raymond Cloyd talks about some of the more prominent invaders, and what to do about them. He also recommends gardeners clean up around their growing areas to help squelch the return of damaging insects next year.

Cloyd 10-09 

LATE VEGETABLE HARVEST– The summer vegetable gardening season is at an end…but you still have tomatoes on the vine and peppers on the plant that you don’t want to go to waste.  Ahead of that first killing frost, you can go ahead now and harvest those.  Through proper handling and storage, K-State horticulturist Ward Upham says those un-ripened tomatoes and peppers can still make for good-quality produce.

Upham 10-02

PLANTING SPRING BULBS– It has become something of an annual landscaping ritual with many homeowners: planting spring-flowering bulbs in the fall.  While you can be as creative as you’d like with these bulbs, Riley County Extension horticultural agent Gregg Eyestone says there are a few planting principles than need to be followed if you want to enjoy a colorful flower display in the spring.

Eyestone 09-25 

ASSORTED FALL INSECTS– Though the variety of insects that attack garden vegetables during the growing season is starting to dwindle now, there are a couple of pests that gardeners need to remain on guard for, according to K-State horticultural entomologist Raymond Cloyd. He discusses blister beetle and squash bug control, which attack cole crops and vine crops, respectively. And he offers good news about the absence of the oak leaf itch mite this fall.

 Cloyd 09-18

FALL TREE PLANTING Summer is quickly giving way to fall.  And for homeowners looking to add one or more new trees to their landscape, this is a great time to plant those trees.  In fact, research has proven that fall-planted ornamental trees establish themselves quicker than those planted in the spring. K-State ornamental horticulturist Jason Griffin explains the advantages of fall tree planting.

Griffin 09-11

FALL COMPOST USE– If you as a homeowner or gardener have been composting plant material for eventual use, the fall offers a great opportunity to do just that. Specifically, Johnson County Extension horticulture agent Dennis Patton says those who plant or overseed the lawn this fall will find a layer of compost could be beneficial to grass establishment. And that working compost into the garden soil is a good way to ready that area for next year’s production.

Patton 07-03

MORE HORTICULTURAL BUGS– Summer is here in full force, and with it, the usual collection of insects that try to work over our landscapes and gardens.   This week, K-State horticultural entomologist Raymond Cloyd talks about three such pests, and what can be done about them:  fall webworm in select landscape trees, squash bugs in garden cucurbit crops, and grasshoppers, well, everywhere.

Cloyd 06-26 

LAWN GRUBS AND NUTSEDGE– There are two common pest problems in home lawns that homeowners can take measure against at this stage of the summer…white grubs and nutsedge.  Being selective about the grubicide and herbicide one uses, respectively, is important.  K-State horticulturist Ward Upham offers recommendations on mid-summer control of these pests.

Upham 06-19

POTATO AND ONION HARVEST– Harvest time is drawing near for a couple of the more popular garden vegetables…potatoes and onions.  Knowing when to dig up the finished product is important to its final quality…as is the post-harvest handling of same. Riley County Extension horticulture agent Gregg Eyestone offers his recommendations on optimizing your potato or onion harvest.

Eyestone 06-12

MORE LANDSCAPE INSECTS– It’s been a banner year for insect activity in home landscapes. K-State horticultural entomologist Raymond Cloyd reports on several pests that homeowners may notice, including aphids on assorted hardwood trees, and insect-inflicted gall damage to tree leaves. He also gives homeowners the go-ahead to treat landscape evergreens for bagworms.

Cloyd 06-05

TWO TREE ILLS– Homeowners with either sycamore or ash trees in their home landscapes may be taken aback by the sudden loss of leaves from those trees in recent weeks. There’s no need for panic, or action. K-State horticulturist Ward Upham says this is the result of two pest issues…a disease on sycamore, and an insect on ash. In both cases, the trees will almost invariably bounce back just fine.

Upham 05-29

BUGS IN THE LANDSCAPE– A number of insects are already working on landscape trees.  And K-State horticultural entomologist Raymond Cloyd wants homeowners to be aware of a couple of them: the eastern tent caterpillar, which is causing damage to assorted hardwood trees, and the European elm flea beetle, which is a lesser-known pest. He talks about whether control of either is warranted.

Cloyd 05-22

CEDAR RUST DISEASE– Those vivid orange galls that show up on cedar trees in the spring quickly catch one’s attention. Those are actually a pathogen called cedar apple rust…and they can serve as the source for rust infestations on landscape trees other than cedars. K-State plant pathologist Judy O’Mara talks about the nature of cedar rust, and steps homeowners can take to protect their trees.

O'Mara 05-15 

PRUNING DAMAGED TREES– Spring storms can take a substantial toll on landscape trees. If high winds have led to broken limbs, those need to be pruned out…and depending on the magnitude of that damage, that may or may not be a project a homeowner would want to take on. K-State horticulturist Ward Upham discusses properly pruning storm-damaged trees.

Upham 05-08

MID-SPRING LANDSCAPE INSECTS– As the weather is steadily warming up, insect activity in gardens and landscapes is picking up.  K-State horticultural entomologist Raymond Cloyd is keeping track of the most prominent insects out there so far.  He discusses three landscape insects: scale on pine trees, praying mantis, and lilac ash borers, and what, if anything, homeowners should do about them.

Patton 04-24

PINE TREE DISEASES– Understandably, homeowners become worried when the needles on their landscape pines start turning yellow. They often fear that pine wilt disease has set in. However, there are two other less-severe pine disease that cause that yellowing, and those can be controlled with the proper treatment. K-State plant pathologist Judy O’Mara discusses pine tip blight and Dothistroma needle blight.

O'Mara 04-17

LAWN WEED CONTROL– The weeds are popping up in home lawns, especially the usual suspects like henbit, chickweed and dandelions. K-State horticulturist Ward Upham covers the strategies for controlling these weeds, pointing out that the most effective control for the winter annuals starts with a fall treatment. However, now is the best time to implement crabgrass control.

 Upham 04-10

SUPPORTING GARDEN CENTERS– The disruptions caused by COVID-19 shouldn't dissuade homeowners from engaging in their normal gardening activities. Extension state leader in horticulture at Kansas State University, Cheryl Boyer, says that outdoor gardening is a perfect way to ease the stress from the current situation.  And local garden centers are going out of their way to accommodate home gardeners and their needs.

 Boyer 04-03

EXTENSION HORT SERVICES– K-State Research and Extension is in a mode of limited operation because of the coronavirus situation, however home gardeners can still benefit from the informational services that it provides as another growing season gets underway.  That’s the message this week from the Extension state leader in horticulture at K-State, Cheryl Boyer.

K-State horticulturist Ward Upham discusses readying the tree’s root ball for planting as well as digging, and then backfilling, the planting hole appropriately.

Upham 03-06

EARLY LAWN CARE– Signs of spring are starting to show up.  And homeowners with cool-season lawns can start thinking in terms of early spring lawn management. K-State turfgrass horticulturist Jared Hoyle goes over several things to consider, including lawn aeration for healthier grass, early broadleaf weed control, and fertilization as the grass greens up.

Hoyle 02-28

GARDEN SOIL TESTING– Signs of spring’s arrival are starting to turn up.  Ahead of this next growing season, homeowners and gardeners might want to check the soil nutrient levels in their lawns and gardens.  That can be done via a soil test, with samples sent to Kansas State University’s soil testing laboratory for analysis.  Johnson County Extension horticultural agent Dennis Patton discusses that process.

Patton 02-21

FRUIT TREE PRUNING– Before spring budding begins, home fruit gardeners would be wise to inspect their fruit trees for pruning needs. This is a great time to conduct corrective pruning, according to K-State horticulturist Ward Upham…provided the recommendations on how to go about it are followed.

Upham 02-14 

DOWNSIZING HOUSE PLANTS– What can you do with a favorite houseplant that's become overgrown?  Well, there’s a technique for downsizing that plant without harming its appearance or future growth.  It’s called air-layering, and Riley County Extension horticultural agent Gregg Eyestone explains how to do it.

PLANTING FOR POLLINATORS– Winter is a great time to plan out the next season of ornamental gardening.  A K-State ornamental horticulturist offers this suggestion: look into adding plant material that will attract bees and other pollinators to the home landscape. Cheryl Boyer says there’s been quite a bit of research lately on the kinds of plants that appeal to pollinators. She talks about what’s been discovered.

Boyer 01-10

VEGETABLE GARDEN PLANNING– During one of these colder winter days, vegetable gardeners can make the most of their time by planning ahead for next year’s gardening. K-State horticulturist Ward Upham encourages gardeners to map out the garden plots for planting, take an inventory of holdover seed and test it for viability, and place orders for new seed.

Upham 12-20

DORMANT LAWN SEEDING– During one of the few pleasant days winter typically offers, homeowners can actually conduct a little lawn care…by seeding bare spots in the cool-season lawn. K-State turfgrass specialist Jared Hoyl says this dormant seeding approach can be successful. He explains how to do it.

Hoyle 12-13 

HOUSE PLANT CARE– House plants can look a little ragged during their indoor winter stay -- often the result of insufficient light, which is normal during these shorter day lengths. K-State horticulturist Ward Upham says that needs to be factored in when caring for house plants until they can be moved outdoors in the spring.

Upham 12-06

WINTERIZING LAWN AND GARDEN STUFF– Fall is steadily giving way to winter.  This is an excellent time to winterize lawn and garden equipment and store it away for the winter.  And now that those potted plants have been moved indoors for the season, Johnson County Extension horticultural agent Dennis Patton says they deserve a little attention as well. 

 Patton 11-29

BASIC POINSETTIA CARE– Widely considered a staple of Christmas season decor, poinsettias, are showy plants that are reasonably easy keepers. However, they still deserve attention every so often during their holiday run. Riley County Extension horticulture agent Gregg Eyestone covers the basics of poinsettia care, which generally apply to all other house plants.

Eyestone 11-22

GROWING AMARYLLIS BULBS– Flowering amaryllis can be a great complement to the traditional poinsettias as holiday potted plants in the indoor setting. Now is the time to pot amaryllis bulbs and start them on their way to sprouting and blooming. K-State horticulturist Ward Upham goes through the steps to promoting those huge amaryllis blooms.

Upham 11-15 

USING FALLEN LEAVES– Very soon, all the landscape deciduous trees will lose their leaves.  While most homeowners look at those leaves as a clean-up chore, Johnson County Extension horticultural agent Dennis Patton looks at them as an opportunity.  He talks about mulch-mowing those leaves to create an organic resource for either the lawn or garden…and about utilizing fallen leaves in beneficial ways.

Patton 11-08

FINAL INSECT PRECAUTIONS– Insect activity in around home landscapes has wound down for the season.  Even so, what insects remain are still looking for a warm place to overwinter.  K-State horticultural entomologist Raymond Cloyd reminds homeowners about sealing up their houses and outbuildings to keep bugs out.  He also talks about protecting fruit trees from winter insect damage with dormant oil treatments.

 Cloyd 11-01

FALL LANDSCAPE INSECTS– Despite the recent and widespread freezing temperatures, a number of insects remain active in home landscape settings.  Some, like Asian lady beetles, are attempting to move indoors for the winter, while others, like green June bug larvae, may look imposing as they move about.  This week, K-State horticultural entomologist Raymond Cloyd discusses those and other pests, and what, if anything, homeowners should do about them.

 Cloyd 10-25

NEW LAWN MANAGEMENT– Once a homeowner successfully seeds a new cool-season lawn like fescue in the early fall, the management doesn’t stop there. To give that new grass the best opportunity to get off to a healthy start, K-State turfgrass horticulturist Jared Hoyle says post-seeding fertilization and weed control need to be considered.

Hoyle 10-18

FALL ORNAMENTAL PRUNING– Once fall weather turns colder for good, there’s a great temptation for homeowners to prune landscape trees and shrubs…their thinking being that those plants have gone dormant, and no harm can be done. Quite the contrary, according to K-State horticulturist Ward Upham.  He says considerable damage to woody ornamentals can occur if we get too carried away with fall pruning.

 Upham 10-11

FINAL VEGETABLE HARVEST– Fall weather conditions have checked in, bringing a close to warm-season garden vegetable production. Those tomato and pepper plants are all but done for the season, so what production remains can be harvested and stored now. Riley County Extension horticulture agent Gregg Eyestone talks about doing that very thing.

Eyestone 10-04

FALL TREE PLANTING– For most durable landscape tree species, fall planting is a great alternative to spring planting.  And now is the time to prepare the planting site and get that new tree into the ground, so that it can be well established before winter sets in.  Johnson County Extension horticultural agent Dennis Patton offers the basic guidelines to planting new landscape trees over the next several weeks.

Patton 09-27

PLANTING SPRING BULBS– Summer is slowly but surely giving way to fall.  And these next few weeks are an excellent time to plant spring-flowering bulbs in the home landscape.  As with any landscaping project, site preparation and planting technique make a huge difference in the bulb display that will result next spring. K-State horticulturist Ward Upham goes over the proven bulb-planting procedure.

Upham 09-20

FALL LAWN SEEDING (part 2) Once a homeowner seeds a new fescue lawn, or overseeds an existing lawn, the project is hardly over.  There are three critical steps yet to follow:  fertilization, weed control and watering. K-State turfgrass specialist Jared Hoyle returns to cover those important inputs that are necessary for success when planting fescue or other cool-season grass in the fall.

Hoyle 09-13

FALL LAWN SEEDING (part 1)– Summer is grudgingly giving way to fall.  That means it’s time to seed, or overseed, fescue and other cool-season lawns.  Successfully planting a lawn sets the tone for that lawn’s long-term health and well-being. In the first of a two-part visit, K-State turfgrass specialist Jared Hoyle talks about preparing the planting site, seeding rates and seeding method.

Hoyle 09-06

APPLE AND PEAR PICKING– Home-grown apple and pear picking time is here, or nearly here.  K-State horticulturist Ward Upham says determining ripeness differs between these two fruits.  He discusses the guidelines for harvesting apples and pears, noting that one should be allowed to ripen on the tree, and the other should not.

Upham 08-30 

LANDSCAPE BAGWORM ONSLAUGHT– K-State horticultural entomologist Raymond Cloyd says he’s never seen anything like it…the explosion of bagworms, not only on landscape evergreens, but on other landscape ornamental plants as well. He talks about what can, and can’t, be done to control bagworms at this stage of the season and the potential plant damage that can be expected if homeowners wait until next spring to take action.

Cloyd 08-23 

FALL LAWN RENOVATION– The heat of summer will soon give way to cooler early fall temperatures…the perfect conditions for renovating a tall fescue lawn.  Homeowners can start planning for that project right now, and K-State turfgrass specialist Jared Hoyle talks about the initial steps to overseeding fescue or completely starting over.

Hoyle 08-16

LATE SUMMER PRUNING– Homeowners: have you tired of having your hat knocked off by that low-hanging branch while you’re mowing? Or are your landscape shrubs growing into your walkway or other places you’d rather it not be?  A light late-summer pruning might be in order. Riley County Extension horticultural agent Gregg Eyestone covers the recommended pruning techniques.

Eyestone 08-09

CURRENT TOMATO PLANTS– Garden tomato plants should be hitting their productive stride right now.  And right in step, Johnson County Extension horticultural agent Dennis Patton says various pest problems are making their presence known on tomato plants and fruit.

Patton 08-02

LANDSCAPE BEETLE ACTIVITY– Two kinds of large green beetles can routinely found in home landscapes right now.  One is harmless to landscape plants…the other is quite the opposite.  That’s why it’s important for homeowners to accurately identify these before taking any sort of control action.  K-State horticultural entomologist Raymond Cloyd talks about distinguishing between the Japanese beetle and the green June beetle.

Cloyd 07-26

GARDEN FRUIT ISSUES– The “dog days” of summer are here…hot days and warm nights. That combination often hinders fruit production on garden tomatoes. However, K-State horticulturist Ward Upham urges growers to remain patient because once the extreme heat moves out, tomatoes should start setting fruit again. He also talks about slow fruit set on cucumbers and other vine crops.

Upham 07-19

LAWN AND GARDEN BUGS– Insect activity in home landscapes and gardens is at its mid-summer norm.  And in many cases, responding with control measures would be warranted. K-State horticultural entomologist Raymond Cloyd talks about three such pests and what can be done about them: Japanese beetles on roses and other ornamentals, green June beetles on fruit crops and squash bugs in vegetable gardens.

Cloyd 07-12

WARM-SEASON LAWN CARE– By their very nature, warm-season lawn grasses are better equipped to endure the heat of summer. Even so, they do require some care. K-State turfgrass specialist Jared Hoyle says that includes in-season fertilization of zoysia, bermudagrass and buffalograss.

 Hoyle 07-05

HARVESTING GARDEN POTATOES– For most home gardeners, their potato crop got out of the gate slowly this year, because of the wet spring weather.  But now, those potatoes should be nearly harvest-ready. Johnson County Extension horticultural agent Dennis Patton offers guidelines on when to dig those potatoes and how to properly store them for long-term enjoyment.

Patton 06-28 

TROUBLESHOOTING TOMATOES– With the arrival of summer heat, garden tomatoes ought to start taking off soon. With that, Riley County Extension horticultural agent Gregg Eyestone, says gardeners may see signs of tomato plant stress, in the form of leaf curl and various leaf diseases. He talks about what, if anything, should be done to curb these conditions.

Eyestone 06-21 

INSECT PEST PROTECTION– The abundant moisture this spring has created a thriving environment for a variety of insect pests. K-State horticultural entomologist Raymond Cloyd offers advice on protecting ourselves from ticks, mosquitoes and chiggers. He also explains how to best detect and control slugs.

Cloyd 06-14

GARDEN FERTILIZER SIDEDRESSING– As the growing season swings into full gear, home vegetable and flower gardeners might want to consider fertilizing their crops once more. This is called “sidedressing” and the procedure differs with the various plants. K-State horticulturist Ward Upham explains why fertilizer sidedressing is important to garden productivity, and covers some of the general guidelines for doing so.

Upham 06-07 

LAWN INSECT UPDATE– The recent wet weather has done nothing to deter several irritating insects from thriving in home lawns. K-State horticultural entomologist Raymond Cloyd provides an update on three prime examples: ants migrating from lawns into dwellings, bagworms now active on landscape evergreens, and ticks building up in huge numbers and attaching to people and pets.

Cloyd 05-31

OVERSOAKED LAWN MANAGEMENT– Home lawns have been soaked to the point of oversaturation.  Even if it’s not outright flooding, K-State turfgrass specialist Jared Hoyle says these conditions can be detrimental to that lawn grass, so a little extra care in lawn management may be in order.

Hoyle 05-24 

ORNAMENTAL TREE STRESS– With the abundance of moisture in the region this spring, landscape ornamental trees should be doing just fine. However, that may not be the case. K-State horticulturist Ward Upham has been seeing heavy seed production on trees and he's advising homeowners to monitor the condition of those trees very closely into and through the summer.

Upham 05-17

CONTAINER GROWN VEGETABLES– Since garden soils in much of the region remain soaked by the persistent rainfall, home gardeners might consider planting tomato and pepper transplants in containers instead. Done correctly, container-grown vegetables can be highly productive. Johnson County Extension horticulture agent Dennis Patton offers basic guidelines for establishing tomatoes and peppers in containers.

Patton 05-10

MORE HORT INSECTS– The insect activity in home lawns and gardens is really accelerating, according to K-State horticultural entomologist Raymond Cloyd. Elm leaf beetles on landscape trees, ants and termites around the foundation of homes, and cucumber beetles in vegetable gardens are particularly active. Cloyd talks about what, if any, damage they can inflict, and what to do about them.

Cloyd 05-03 

LANDSCAPE ORNAMENTAL PESTS– An array of insects are now escalating their activity on landscape ornamental trees and shrubs. K-State horticultural insect specialist Raymond Cloyd says homeowners should act now to control the pine saw fly and the lilac ash borer, while they can wait until later this spring to treat bagworms.

Cloyd 04-26

LAWN WEED CONTROL– With spring weather finally here for good, homeowners should start ramping up their lawn weed control programs.  K-State turfgrass specialist Jared Hoyle says to start by attacking broadleaf weed issues like dandelions that survived last fall and assorted other weed problems. He also recommends putting down a pre-emergence control product against summer lawn weeds.

Hoyle 04-19

ORNAMENTAL PEAR ISSUES– Ornamental pear trees, such as the Bradford pear, can be found regularly in home landscapes.  Those trees are not intended to bear fruit.  However, K-State horticulturist Ward Upham says in recent years, because of the proliferation of ornamental pear cultivars, some trees are now setting fruit, which then becomes an issue when that fruit drops to the ground.

Upham 04-12 

EARLY LAWN AND GARDEN INSECTS– This past winter was cold and wet for an extended time…giving rise to the notion that lawn and garden insects may have struggled to survive those conditions.  K-State horticultural insect specialist says the winter likely did little to reduce the likelihood of insect activity in this new growing season. Raymond Cloyd talks more about that, and about the first insects homeowners and gardeners will likely see in the next couple of weeks.

 Cloyd 04-05

STARTING VEGETABLE TRANSPLANTS– It’s not too late for home gardeners to start their own warm-season vegetable transplants from seed. K-State vegetable production specialist Cary Rivard walks through the basic steps to successfully seeding and growing sturdy transplants with a promising yield potential. 

Rivard 03-29

MANAGING ASPARAGUS BEDS– Asparagus is one of the very first things harvested from the home vegetable garden. While established asparagus beds are generally easy to maintain, they do need some attention before those first spears are cut. K-State horticulturist Ward Upham offers tips for early-spring asparagus management, including fertilization and weed control.

Upham 03-22 

HOME LAWN WINTERKILL– It was a fairly harsh winter in this region.  And that has homeowners wondering if their lawn grasses were adversely affected by the extended cold and wet conditions. K-State turfgrass specialist Jared Hoyle says while the likelihood of outright turfgrass winterkill is relatively low, some limited damage may have occurred.

Hoyle 03-15

PLANTING GARDEN RHUBARB– Despite the slow, weather-impeded start to the vegetable gardening season, home growers still have plenty of time to establish a rhubarb planting. K-State horticulturist Ward Upham says rhubarb transplants are managed a bit differently compared to other popular vegetables.

Upham 03-08 

GARDEN SOIL TESTING– It’s not needed every year, but if it hasn’t been done for a while, gardeners would be wise to sample the nutrient content of their soils. Johnson County Extension horticultural agent Dennis Patton says the steps to conducting a soil test are fairly simple, and can tell gardeners a lot about soil fertility management for the upcoming growing season.

Patton 03-01

TOP TOMATO VARIETIES – Tomato-planting time is still a couple of months away.  Even so, there’s a reason for home gardeners to start thinking about the varieties they would like to grow this year. K-State horticulturist Ward Upham shares examples of tomato lines that rated very highly in K-State’s annual tomato evaluation trials on the basis of both yield and fruit size.

Upham 02-22

PRESERVING CUT FLOWERS– Now that Valentine’s Day has come and gone, how long can those roses or other cut flowers and flowering plants given for the occasion be preserved? That depends on several factors, according to Riley County Extension horticulture agent Gregg Eyestone.

Eyestone 02-15

DAMAGED TREE PRUNING– Heavy, wet snow and ice have exacted a toll on numerous landscape and fruit trees this winter. Johnson County Extension horticultural agent Dennis Patton says the sooner these damaged trees are cleaned up the better. He covers how to properly prune winter damaged trees.

Patton 02-08 

ON-LINE PLANT MARKETING– A new avenue for marketing horticultural plant material is emerging:  plant sales through major on-line retailers.  It’s a development that K-State horticultural marketing specialist Cheryl Boyer has taken keen interest in, and in fact is researching.

 Boyer 02-01

ALL-AMERICAN VEGETABLES– As vegetable gardeners scan the winter catalogs for new things to plant this spring, K-State horticulturist Ward Upham says they should consider several varieties that have just been named All-American Selections for this year. These earn their high ranking based on productivity and adaptability to a wide range of growing conditions.

Upham 01-25 

PRUNING LANDSCAPE ORNAMENTALS– As winter grudgingly affords us a few decent days outdoors, homeowners can go ahead and conduct whatever pruning is necessary on certain landscape trees and shrubs. K-State forester Charlie Barden offers general guidelines on making pruning decisions, including what plant material to prune now and what should be left for later in the year.

 Barden 01-18

STARTING VEGETABLE TRANSPLANTS – Home vegetable gardeners who are wanting to get a jump on the growing season can soon start those early-season transplants from seed.  It’s an approach that K-State horticulturist Ward Upham fully endorses. However, following the recommended steps to starting plants from seed is a must.

Upham 01-11

FIREWOOD HEAT VALUE– Nothing beats the warmth of a fireplace or wood stove to take the edge out a cold winter day or night.  Knowing the heat value of different types of wood will make the experience that much better.  K-State horticulturist Ward Upham explains why some firewood burns hotter and longer, and goes over the actual heat output ratings of the different tree species. 

Upham 12-21

PROTECTING WOODY ORNAMENTALS– The brunt of winter is still ahead, and during the harsher weather, rabbits and other rodents are searching for nutrition. Often, they find it in the bark and tissue of young landscape trees and shrubs. And that feeding can do permanent damage. Riley County Extension horticultural agent Gregg Eyestone talks about protecting those woody ornamentals from feeding.

Eyestone 12-14

ATTRACTING BACKYARD BIRDS– Winter is here, and what better way to add life to a frozen backyard setting than to put out songbird feeders.  Bird feeding is something the whole family can participate in and enjoy, says Geary County Extension agent Chuck Otte, a trained ornithologist who has produced a series of Extension fact sheets on backyard bird feeding. He shares some of the basics on bird seed selection and feeder placement.

Otte 12-07 

WINTERIZING LAWN AND GARDEN EQUIPMENT – On one of these winter days where it’s too unpleasant to work outdoors, homeowners and gardeners might instead turn their attention to their lawn and garden power equipment and hand tools.  Readying them for the next growing season is a good project to take on right now, according to K-State horticulturist Ward Upham. He walks through the steps to winterizing mowers, tillers, hoes, rakes and other common equipment.

Upham 11-30 

MORE INDOOR BUGS– As the colder weather will likely be around for a while, several landscape insect species are setting up shop inside homes and outbuildings.  By and large, these are nothing more than a nuisance, according to K-State horticultural entomologist Raymond Cloyd.  Homeowners can take simple steps to dispense with these pests…including those who hitchhiked indoors on potted plants as they were brought in for the winter.

Cloyd 11-23

COLD WEATHER AND ROSES– Winter came early over most of Kansas, with unusually cold temperatures in early November. That may have caught landscape roses unprepared, according to Johnson County Extension horticultural agent Dennis Patton. He talks about that possibility, and the simple steps to winterizing grafted roses.

Patton 11-16

BUGS IN THE HOUSE– With the weather steadily turning colder, landscape insects are seeking shelter indoors. Most of them are just a nuisance, and can be dealt with without the use of an insecticide. This week, K-State horticultural entomologist Raymond Cloyd talks about the invaders he’s hearing about the most this fall: Asian lady beetles and spiders.

Cloyd 11-09
