Hello, I have carpenter ants attacking one of my trees and the woodpeckers pick at it for the ants and they are killing my tree. Any help would be great.
Thank You
Brian
I have a 70 year old silver maple that has lost 2 limbs in severe rain and wind storms, one limb in one storm and years later another limb. Our neighbor is saying that the tree is unsound. How can I know if this is true? It looks healthy to me and has leaves on all but one branch in the growing season. I appreciate your help. Peg
Hi Peg. Sorry to hear about the downed limbs on your tree. While it’s hard to say without looking at the tree, your neighbor’s concern about the tree may be valid, and is certainly worth considering. You’ll need to contact a certified arborist to look at the tree. You can find one on this list of certified arborists in Minnesota.
If the tree is near a property line or could fall on your neighbor’s property, you may also want to review our Minnesota law and trees series.
Thanks for the question and good luck! I hope the tree’s OK.

I have an old maple tree that last year was fine…this year, no leaves, none! Help! What should I do?
Hi Elaine. Sorry to hear about your maple tree. Failure to leaf out is a sign of a pretty serious problem. Obviously, without foliage the tree can not survive, and will likely need to be taken down. If you’d like to learn more about possible causes or what to do next, .he UMN Forest Resources Outreach and Extension line may be able to help. They’re reachable at 612-624-3020 or treeinfo@umn.edu. Hope this helps.
I have some ash trees that are bending to the ground like a rainbow effect, they are very healthy. I don’t want to cut them down. What can be causing this? There about ten total they are about 5 to 10 inches in diameter and twenty to thirty feet tall. Help Please!
Hi Robyn. Sounds like storm damage. Are you in an area that was affected by last Friday’s windstorm?
