Q.What is chewing our branches off of our willow tree?
We live in Southern New Hampshire, and have a 10 year old willow tree that something keeps chewing the branches off, from 1/8″ to 3/4″ diameters. The damage caused is bad and has stunted the growth.
We have wrapped a 2′ high metal piece around the trunk hoping to prevent what ever it is from being able to climb up. Happens year round.
Hope you have some suggestions.
Thank you!
Chris

This can be hard to diagnose if you do not physically see the pests. To know what it is causing the damage would help, as there could be a different treatment based on what the pest is. If you can upload some pictures here, then it will really help me to identify the cause of the problem.
