Web worm in my weeping cherry

Question

I cut off the branch where the web worm “nest” was attached. There is also plenty of dark sap seeping from the trunk. What else would you suggest? Thanks

Answer 1

Cutting off the branch was the most important step. These articles have a good explanation of other steps to control these pests:

Is the sap oozing from the wound where you cut the branch, or from a different site on the trunk? In the second case, there may be a problem called gummosis. This can be caused by general stress (such as from the webworms or from the removal of one branch) or by certain diseases and infestations:
