Linden tree roots growing into garage

Asked May 22, 2019, 11:15 AM EDT

I have a large, old (18” diam.) Linden tree. It’s very healthy, but it’s toots are invading my driveway and garage. I’ve had the advice of two people...one said to cut the roots where they’re encroaching, and the other said that if I cut the roots the tree will die. I need an expert opinion. If possible, qait would be best if someone could come see the problem. Jean

It is true that cutting roots will affect the health of a tree, potentially causing it to decline or fall. To what extent root pruning affects a tree will be influenced by the age, size, and lean of the tree, the size of the roots, the number of cuts, and other factors. Take a look at this article for further information about the factors that affect tree response. http://hort.ufl.edu/woody/root-prune-guidelines.shtml

A large old tree like the one you describe may be severely affected. If you still want to consider root pruning, I encourage you to consult with a certified arborist who can assess your tree and the situation. You can find a certified arborist by using the "find an arborist" search on this page. http://www.treesaregood.org/
