A GREENER VIEW
Black knot fungus and mulch
Q: I have a flowering cherry tree that has ugly “lumps” growing up the trunk and on the bigger branch, the tree is around 20-feet tall. I have been told that these growths are harmless, which I find hard to believe. My question is: Will they kill my tree?
A: It sounds like the tree has a fungal disease called black knot. It is a fungal canker of apricots, cherries and plums. The cankers look like charcoal wrapped on the branch. They enlarge and kill the branch over two years. Whole trees die when the trunk is girdled or many branches are infected. The tree is weaker and may die of other causes.
Fungicide sprays can help stop new infections, but they do not cure old ones. It is probably too late to spray this year. The sprays are typically done as new growth comes out, and then again when the tree is flowering.
An infected branch can be pruned off if it is cut at least 8 to 10 inches closer to the trunk. During the first spring, the infected spot on the branch is very hard to find. It will swell and will be an olive green color. By fall, it will develop into the black knot. Pruning is often done in winter when the knots are more visible.
