Honey locust tree disease

Asked August 16, 2014, 1:03 PM EDT

Overall the honey locust tree appears healthy in spring and within a month or so the leaves on the tips of the branches die leaving only the branch (about 6 inches). This happens on all the tips of the branches on the tree. Several other honey locusts in the neighborhood have the same thing. What can I do to prevent this from happening next year?

It is possible that these trees are suffering from a fungal disease. This has been a banner year for fungal diseases with the cooler and wetter than average weather. Honeylocusts are most susceptible to Nectria Canker and the Honeylocust plant bug..

Because there are so many possibilities you may want to submit a sample of the leaves.branches that are showing this problem. It is important to use the proper "medicine", depending upon the individual threatening organism :

At the same time you should take a look at some of these links to see if the symptoms match what you are seeing on your tree:

I hope this is helpful. Please contact AaE again if you have further questions.
