Plant – Pumpkins for a Halloween harvest, tomatoes, sweet potatoes.
Iron chlorosis – Trees planted in soil whose pH is too high may be suffering from iron chlorosis. This is the time to treat it. You can do it yourself with a home injection system such as Medi-Caps and NutriBooster if the tree is small, or it will be easier to have a professional do it if the tree is big, extension agent Bob Neier says. Or apply a sulphur-containing fertilizer such as South-West Green Maker at a rate of 5 pounds per 1,000 square feet to the entire lawn, not just around the tree, in spring and fall for a few years.
Scale – There has been a moderate amount of Lecanium scale on plants, Neier says. Crawlers were out about a month earlier than normal this year with optimum treatment time being early and mid-May this year, he says. Scale does not kill trees but is a nuisance and can weaken the trees. Horticultural oil that is refined also can be used in the summer when the temperature is high, Cathy Brady of Brady Nursery says. Otherwise, dormant oil next early March or a soil drench containing Imidaclorid in late February can be helpful, Neier says. For now keep the trees adequately watered. Be sure to follow label guidelines for the weather and rate of application.
Dill tip – When growing dill in a container, use a pot that is at least 10 inches deep to accommodate the taproot, the National Garden Bureau says.
Bagworms – Search conifers for bagworms. Treat for them after all eggs have hatched and worms are still small, says Bob Bauernfeind of K-State. Apply thoroughly for good control.
New director at Dyck Arboretum – Scott Vogt, longtime horticulturist at Dyck Arboretum of the Plains in Hesston, has been named its director after a nationwide search. “Scott’s commitment and passion for the arboretum and his years of knowledge about the community, the plant world and the intention of the Dyck Arboretum’s mission made him the best candidate to lead the arboretum into the next phase,” Christine Downey-Schmidt, arboretum board member and co-chair of the search committee, said. Vogt has a bachelor’s degree in horticulture from Kansas State University. Dyck Arboretum, one of the largest native-plant gardens in the region, is run by Hesston College.
