Question
I moved into a new home 3 weeks ago and have noted that the weeping willow trunk looks as though something has borrowed holes all over the trunk.  I do not "see" insects and the leaves are present-any idea what the cause is and how to treat?
Thank you!!

Answer
Hi how are you? There are a few things that can make this happen to a tree.The tree could have a bore insect of some type which left untreated can kill your tree.It may also be a bird called a sapsucker which will do this to the bark and leave holes on the bark but wont kill the tree.I would have a Certified Arborist come out and look at the tree to find out what is the problem and do treatment if treatment is needed.It is better to be safe then sorry
