Here are some of the questions master gardeners fielded on their hotline this week. They answer questions from 9 a.m. to noon and 1 to 4 p.m. weekdays at 316-660-0190.
How do you control suckers growing at the base of trees?
Pruning them out several times a summer is the best way to handle this. A product called "sucker stopper" is no longer found on the market, but if you find some, just spray the suckers when they are about 6 to 10 inches tall. Horticultural vinegar can be sprayed on them, and it will burn them back without hurting the tree (but they will regrow). Do not use a herbicide on suckers — they will damage or may kill the tree. The best product to buy is a new pair of hand pruners!
