Gumming Of Prune Trees

Categories: Pests and Diseases of Plants

I write to ask for information concerning my prune trees. They are from

two to six years old and the gum is exuding from them. As I notice the

branches dying I cut them out, but this doesn't seem to save the tree. I

would appreciate any information you can give me.



This is a pretty hard matter to diagnose from a distance. There is a

good probability that the trouble is caused by sunburn, a point you

could determine on inspection. Whitewash would be a protection against

this and more or less of a cure also. Furthermore, borers may be the

cause, which can be determined by examining the points where the gum

exudes, seeing if any wood grains are present. These borers should be

dug out and whitewash applied, which latter also protects against this

trouble. Lastly, your ground may be drying out, which also you can

determine and remedy.
