Question From: B. Gilman - MAINE
Q: We have a large, beautiful Black Ash tree on our property in Maine. We read that Bayer Tree and Shrub Insect Control is most effective applied in early to mid-spring. It's July, and it's getting hot. Is there any sense in using the insecticide now, or should we wait until next spring? Thank you!
I recommend you get the advice of a certified arborist and have the application done by a professional. They usually do injections that quickly move through the tree. There is no way to tell how long a home owner application will move through the tree. Timing varies from state to state. To find an arborist in your area go to www.tcia.org and enter your zip code. There is another website you can check out: Maine.gov that will give you information speciific to Maine. Best And Happy Yardening, Nancy
