Question
Willow Tree Damage
I have bleed loosing large (20 ft =/-) Weeping willow trees over the past 3 years. Last year I lost one last year and now I have 3 starting this year. The sap start to run from one or more spots. No mater what I do I cant stop the bleeding and I end up loosing the tree.They all show the same symptoms. I have corkscrew willows interspersed with the weeping willows. As of now they are not affected by whatever is affecting the weeping willows.Can you identify the problem and recommend what I can do to stop the bleeding so I don't loose any more trees. I am attaching a photo of a tree I lost last year. Thank You, Jim Hopper Troy, Bradford County, NY.
AnswerLooks like borer attack. These insect bore into the trunk and the tree oozes sap to try and push out the borer. I would recommend that the trunk be sprayed with an insecticide called Merit or Onyx these will kill the insect in the trunk and the sap flow should stop.
