Weeping Cherry Trees
Q.

Web worm in my weeping cherry

Zone Branson mo | Anonymous added on August 28, 2017 | Answered

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

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:
