Dead tree branch
What is killing only part of a branch on my crabapple tree?

Thank you for your question. Is there any way you can send a few pictures of your crabapple tree and the branch? Pictures can be attached to the Ask An Expert portal or you can text them to 775-399-8522.
There are several reasons why you may lose a branch from, insects, sunscald, cankers or physical pressure via animal, wildlife or wind. Or, if it is a small branch the tree may be eliminating branches that do not produce enough leaf to properly photosynthesise.
