I have a columnar Yew which currently is about 18 - 20 feet tall with a spread of about 6 feet. What is the root system like for these trees and what effect will/can it have on the foundations of the house?
The centre of the trunk is only 3 feet from the building. I am concerned for two reasons:
The impact of roots on the footings
The extra moisture content of the soil if it is felled
It is a beautiful tree which at present causes no problem. There are no cracks appearing!
