What causes holes in the trunk of my aspen tree?
Answer(s)
A
Borers. Many kinds of boring beetles attack aspen trees. Trees that are stressed are more susceptible to borer infestation. Developing larvae burrow into the trunk and feed sometimes for several years. Borer wounds often bleed and their tunneling weakens the trunk of the tree and may cause the invasion of fungi. Maintain your trees’ health to prevent borer infestation. Once the borer larvae is inside the heartwood, insecticide applications are futile.

- Many years ago the back nieghbors laid sod about 6 inches higher than our sod and leaned it on the back cedar fence. They also put in small trees about 3 feet from the fence. The trees proved to be junk trees and now we have endless roots protruding above the ground 4-5 inches. If i hit them with the lawnmower cuts of a small bit of root and dulls the blade. Their are too many to cut out, if we lay sod over them will this solve the problem?? Any suggestion would be appreciated. Thanks

- I have a very large, beautiful Cottonwood tree on my property, that is near the property line with my neighbor. She wants to put in a new fence, because the tree has been pushing up the posts for her old fence. The fencing company has said that they can put in a new fence, but they will have to "shave off" a bit of the tree trunk and possibly some of the root near the surface of the ground. I am worried that something like that could lead to the tree getting sick or dying. I want to keep peace among neighbors, but it would be a disaster and very expensive to lose the tree because of something likethis. Can you please tell me if a Cottonwood tree is hardy enough to withstand such a "shaving" procedure?

ANYTHING you might know about this would be much appreciated.
