Sunburst Honey Locust Tree
I have a Sunburst Honey Locust Tree in my backyard. The soil in Madison Heights is sand. Last fall the tree lost its leaves early and this year after the constant rain and heat the tree looks like its shedding all of the leaves. Is there a disease or some other problem with this variety. I have a service that comes to spray this tree Bernadine Karas

The tree is known to be prone to a few pests, and perhaps that is why your service is spraying, although each pest must be controlled at the proper time:
Did you have another question regarding this honeylocust? Did you find any insects on the tree as outlined in my answer a couple weeks ago?
The tree will take time to recover, even if you are watering it now. The larger the tree gets, the more water it needs, and the more restricted the root zone becomes as the roots are also extending well beyond the farthest reaching branches. Another thought- be careful applying weed killers near the tree , avoid the trunk, and large roots.
I’m sorry we can’t do more with just pictures and descriptions. Consider hiring an arborist or sending sample branches with leaves attached to MSU Plant Diagnostic lab, as suggested in the first response. https://pestid.msu.edu
I hope this, and the info given on your first question, is helpful. Thank you.
