Gumming Of Prune Trees
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.
