I have a customer that has a large maple tree with some exposed roots that has an old crappy flower bed around it. They want me to re do it with something classy. I was thinking about a short (3ft or less) dry laid stone wall but my questions are 1. as the tree continues to grow will it push the wall up with the roots? 2. In order to lay the first run of the wall under ground level i will have to cut roots. Will this harm the tree? The wall will be completly around the tree about 10ft from it and i was planning on back filling it with dirt. I am open to any other suggestions also.
