When I bought my house I planted Weeping Willows. I was told by garden center employee that as long as it was 20 feet away from the house that since we have clay soil it would be ok. Now I am not so sure about this and am worried that they may damage my finished basement. I have planted a row of 7 trees and they are beautiful and attract tons of birds/bunnies (especially with their young) and my AC bills have gone down drastically in past few years. One is 8 years old and 4 are 6 years old and 2 are 3 years old. They also provide privacy as my neighbor's property is higher and they put in a huge deck in their back yard which I found intrusive to my privacy. I don't want to murder my beloved trees, but I don't want foundation damage to my home or the neighbors. What can I do? Must I rid my yard of these beautiful trees?
