DIVIDING AND REPLANTING IRIS– As a general rule, iris should be divided about every three to five years to keep the plants from outgrowing their allotted space in the garden and to increase bloom quality. Bearded iris can be divided any time after flowering. In the Midwest, this is often done in August to allow the replanted portions of the plant to have time to develop new roots and become established before colder weather arrives.

BERMUDAGRASS IN TALL FESCUE– If bermudagrass, a warm-season grass, invades tall fescue, a cool-season grass, the bermudagrass will spread and take over. Mid-July is a good time to start controlling bermudagrass in tall fescue lawns. However, the procedure takes about eight weeks to complete and includes spraying with Roundup or another product with glyphosate, scalping the treated area, spraying again with a glyphosate product and reseeding the treated area.
