Q

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

Answer(s)

A

Laying sod over the tree sprouts will not solve this problem. There is no really good solution to this problem.

You could sever the roots that are growing into your lawn by trenching along your side of the fence. Most of the roots will be within the top 12 to 18 inches of soil. Then you could put some type of root barrier along the trench wall, like sheetmetal or plastic sheeting. This will help prevent or at least slow down the growth of tree roots into your yard from their trees.
