LATE-SEASON LANDSCAPE INSECTS– At this point of the growing season, several beneficial insect species are active in home landscapes. K-State horticultural entomologist Raymond Cloyd identifies a couple of those which are quite prominent right now…primarily encouraging homeowners to leave these species be, for they are causing no harm whatsoever to landscape plantings, or anything else.
DIVIDING DAYLILIES AND PEONIES– The month of September is an excellent time to divide and re-plant daylilies and peonies. The recommended dividing process differs from one to the other, as explained by K-State horticulturist Ward Upham. He also talks about re-establishing newly-divided daylily and peony clumps in the flower bed or border ahead of the colder weather to come.
ASSORTED LANDSCAPE BUGS– Summer is gradually giving way to fall. Even so, several insects remain active in home landscapes. The fortunate thing is that homeowners don’t really need to react to those at this stage of the year, according to K-State horticultural entomologist Raymond Cloyd. He talks about fall webworms in trees, scale on euonymus, and previews a new K-State publication on pesticides and bees.
WATERING DRY TREES– The extended drought over a large part of Kansas stressed many landscape woody ornamentals. And though recent rains took some of the edge off of that stress, some trees and shrubs still need special attention with supplemental watering well into the fall. Johnson County Extension horticultural agent Dennis Patton identifies species which should be monitored and prioritized for routine watering.
PREPPING FOR LAWN RENOVATION– This summer’s heat and drought exacted a pretty big toll on fescue lawns in Kansas. Some were pushed past the point of no return, meaning they will need to be renovated this fall. K-State turfgrass specialist Jared Hoyle. says there are a few preparatory steps a homeowner can take right now, leading up to re-seeding or overseeding a fescue lawn.
HARVESTING APPLES AND PEARS– Home orchard managers in Kansas generally have good luck growing apples and pears in our sometimes-fickle conditions. The quality of the harvest rests in large part on picking these fruit at just the right time. K-State horticulturist Ward Upham offers some basic guidelines on determining apple and pear ripeness.
LAWN AND GARDEN INSECT UPDATE– Easing into the latter part of the summer now, an assortment of insects are out in full force in lawns and gardens right now. Some call for control measures, others are creating only cosmetic damage. K-State horticultural entomologist Raymond Cloyd revisits the concerns over Japanese beetles, elm leaf beetles and squash bugs, and adds a new pest to the list: lacebugs.
FALL VEGETABLE GARDENING– If you can look past the mid-summer heat, now is an excellent time to plant a fall vegetable garden. Under good management, cool-season vegetable crops can often exceed spring-planted vegetables in quality and flavor, according to Riley County Extension horticultural agent Gregg Eyestone.
BEETLES AT WORK– Lawns and gardens around Kansas are being besieged by an assortment of beetles that are creating various forms of damage…namely, Japanese beetles on ornamentals and vegetable gardens, green June beetles on fruit crops, and elm leaf beetles on elm trees. K-State horticultural entomologist Raymond Cloyd talks about controlling these problems while also being careful not to harm bee populations in the process.
SUMMER LAWN PROBLEMS– Each summer brings its own assortment of challenges to home lawns. K-State turfgrass specialist Jared Hoyle addresses a couple of common problems he’s been hearing about: infestations of a grassy weed called yellow nutsedge and brown patch disease.
WATERING LANDSCAPE TREES– It’s already been a tough summer for landscape trees and shrubs. Long stretches of hotter-than-normal weather and lack of rainfall has caused considerable stress. As a result, watering may be called for. However, K-State horticulturist Ward Upham says there’s a right way and a wrong way to do that.
LAWN HEALTH ISSUES– Warm-season lawns typically thrive in the summer. However, K-State plant health specialist Megan Kennelly is getting samples from Kansas homeowners that indicate otherwise. In these cases, she says it’s more about environmental stress than plant disease problems.
AN ARRAY OF INSECTS– Lawn and garden insect issues are seasonally abundant right now. Horticultural entomologist Raymond Cloyd offers a quick-hitting look at several of the more common pests and how to contend with them. The lineup includes grasshoppers, cabbage loopers and Colorado potato beetles, as well as continued attention to the bagworm problem on landscape ornamentals.
BAGWORMS AND SPIDER MITES– Insects are out in full force in home landscapes and gardens. K-State horticultural entomologist Raymond Cloyd says bagworms on landscape evergreens, and spider mites on woody ornamentals and garden vegetables deserve some extra attention right now.
MULCH AND FERTILIZE TOMATOES– Tomatoes are the most popular vegetable for home gardeners, not only in Kansas but just about everywhere. K-State Research and Extension horticulturist Ward Upham says now is a good time to mulch tomatoes and give them a boost by applying a nitrogen fertilizer.
INJURY TO LANDSCAPE PLANTS– The crazy weather Kansas has experienced over the last six months may be responsible for some problems in the home landscape. Johnson County Extension horticulture agent Dennis Patton says winter overkill and spray drift from applying herbicides is now starting to show up.
WARM-SEASON LAWNS– Now that the weather has warmed up, warm-season turfgrass like zoysia and buffalograss is growing vigorously. K-State horticulturist Ward Upham says nitrogen is the main nutrient need for these grasses. He covers application rates and how many times to fertilize during the summer.
ASSORTED PLANT BUGS– K-State horticultural entomologist Raymond Cloyd says it’s time to treat landscape evergreens for bagworms. He also addresses several insect concerns in home vegetable gardens, including bean leaf beetles, squash bugs and spider mites…and what to do to keep them from damaging vegetable plants.
TICKS AND ANTS– Summer-like weather has descended upon us…and with it, a proliferation of insect concerns in home yards: most notably, ticks and ants. K-State horticultural entomologist Raymond Cloyd talks about protecting one’s self from tick bites, and about preventing ants from migrating from the landscape into the home.
TRANSPLANTING GARDEN VEGETABLES– Now that warmer spring weather is finally here, home gardeners can safely plant tomato, pepper and other warm-loving vegetable transplants. Riley County Extension horticultural agent Gregg Eyestone says following a few simple steps gets those transplants off to a good start, which is essential to productivity.
SPRING LANDSCAPE INSECTS– Now that true spring weather is taking over, various insects are now asserting themselves in landscape trees and shrubs. K-State horticultural insect specialist Raymond Cloyd addresses two of the primary caterpillar problems that are showing up now: the European pine saw fly and the ash/lilac borer.
LANDSCAPE PLANT DESICCATION– The weather this past winter and now into spring has hardly been kind to landscape woody ornamental plants. Johnson County Extension horticultural agent Dennis Patton offers advice on helping landscape trees and shrubs recover from these adverse conditions.
VEGETABLES AND COLD WEATHER– It’s been an extremely slow start to the spring. And that has home gardeners asking K-State horticulturist Ward Upham if their early-planted vegetables will come through the cold weather in good shape.
CRABGRASS PREVENTER TREATMENTS– Countless homeowners combat crabgrass in their lawns every year. Now is the time to get the jump on this weed by applying a crabgrass preventer. However, the window of opportunity will be closing soon. K-State turfgrass horticulturist Jared Hoyle discusses the timing of crabgrass herbicide applications, and the products most likely to get the job done.
