Question From: E. Moore - Pickerington, Ohio, United States
Q: My crab apple tree's trunk is turning black. It looks like some kind of some kind of fungus is growing on it. Lots of different insects such as bees and lady bugs are feeding off of the blackened area. What is causing this and what can I do so I don't lose this tree?
Your best bet is to have an onsite inspection by a certified arborist - a tree doctor. Trees often have several issues and a "blind" diagnosis could cost you your tree. When my trees look like they have a problem I call an arborist.
