Plant – Tomatoes, sweet potatoes, sweet corn, winter squash, pumpkins (wait until closer to July 4 for a Halloween harvest).
Crabgrass preventer – If you put a crabgrass preventer on your lawn earlier this spring, make the second application by June 15.
New potatoes – “Many gardeners look forward to harvesting new potatoes this time of year,” Ward Upham of K-State writes in this week’s Horticulture 2014. “New potatoes are immature and should be about the size of walnuts. Pull soil away from the base of the plants to see if the tubers are the desired size. If they are, dig entire plants and allow the skins of the exposed tubers to dry for several hours before gathering. These young potatoes are very tender and prone to the skin ‘slipping’ unless they are given a few hours to dry. Even then these immature potatoes will not store well. Red-skinned varieties are often preferred as they are the earliest to produce.”
“Honeydew” rain – If you notice “honeydew” raining down from trees, they have lecanium scale, Upham says. Branches and leaves of trees can also turn black, and branches can die back. If damage is significant to trees, this is the time to treat, followed by another spray in 10 days, Upham says. Registered products include permethrin (under numerous trade names), cyfluthrin (Tempo, Bayer Vegetable and Garden Insect Spray), dinotefuran (Ortho Tree & Shrub Insect Control Ready To Use Granules), carbaryl (Sevin) and malathion. In the fall, imidacloprid (Bayer Tree and Shrub Insect Control, Bonide Systemic Granules IC) can be applied.
Fruit tips – Upham has these reminders for fruit growers:• Remove fruit from heavily loaded apples and peachesso that apples are spaced an average of every 4 inches and peaches every 6 to 8.
• Remove sucker growth from the base of fruit trees and grape vines.
• Remove water sprouts that grow straight up.
• "Comb" new growth on grape vines so the new shoots hang down for greater exposure to sunlight.
• Continue disease and insect control to prevent fruit damage.
