Tree of heaven control #798559

Asked June 29, 2022, 12:59 PM EDT

We inherited a grove of 40-foot-high Ailanthus when we moved into our home 9 years ago. We cannot deal with the large trees, due to their large number and proximity to structures a fallen tree could damage. Our goal has been simply to contain the spread of the plants. We snip the young sprouts or trees and paint the cut edge with Bonide StumpOut which has triclopyr. However, we have not stopped the spread of the plant. I am wondering whether painting the cut edge delivers enough poison to be effective, whether we could be doing something else or something different. Also, there is far too much work for us to do ourselves, and we would value advice about how to locate affordable or voluntary help with the poisoning.

Please watch this video and read the web page on ailanthus control. They have  the most effective and up-to-date information available on the subject:

 We are not aware of volunteer groups in your county who will go to private properties to remove invasive species. You may want to contact your county government to learn if any services are available to assist you.
