Hello Nevine,

I’m sorry to hear about your plants. It is difficult to diagnose a problem that is affecting several different species because diseases are species specific and do not spread from one species to the next. And burning bush is a plant that is pretty well pest free with few problems.

That suggests that there is an environmental condition that is causing the problem. Conditions such as too much water—has a sprinkler broken in the area flooding the plants; are the plants located close to a sidewalk where salt was spread over the winter; has the soil or nearby trees been treated with herbicides or insecticides that may harm the plants or have chemicals been sprayed in the area and drifted onto the plants.

The MSU Extension’s Plant and Pest Diagnostic Lab will be able to provide an accurate diagnosis and recommendations for managing the problems. Go to: https://www.canr.msu.edu/pestid/

to learn how to submit a photo/sample to the lab.

If trees are involved a certified arborist will be able to assess the trees. To find an arborist in your area, go to www.treesaregood.org the website of the International Society of Arboriculture.
