Can a thornless female honey locust tree be treated in some way to prevent...
Thank you for your request of assistance concerning you Locust tree problem.
The only means of fruit prevention I was able to find was an application of Florel ethephon. This must be applied to the entire tree at the proper time (late May to early June) in order to be effective. It is available to the home owner but you should consider the size of the tree as it is generally impractical for the average homeowner to apply. I would suggest contacting a tree service for application! Also this must be applied each year. The product can damage metal products if they are nearby and some trees may be sensitive to this product.
An added not there are seedless varieties of Honey Locust available for your consideration.
