Japanese cherry tree w/dead branches
We have a 25 year old Japanese Cherry tree. This year we discovered it has many very dead branches. You can snap them off the tree by just pulling them. The rest of the tree is full of blossoms. Does our tree have a disease? Is their any remedy you would suggest?
Many things can cause a tree's branches to die. We cannot give you an explanation without much more information.
Prune off all dead branches. Follow good cultural practices: Do not pile mulch on the trunk. Mulch should be pulled back several inches from the trunk and not be more than 2-3" deep. Water in times of low rainfall.
Send us photos if you see symptoms such as leaf spotting or borer holes. You can also send us photos of the entire tree, as well as the trunk at the base.
