Our neighbours have a magnificent magnolia planted 1 metre from our border, it is the pride of our street. The problem is that it is digging up the paving to the entrance of my house which is about 2m from its trunk. Is it possible to remove the problem root without damaging the tree. It is approx 10-15 years old and stands at about 20-25ft high. The 2 roots in question are approx 2-3" in diametre. The roots are very close to the surface. I would appreciate any advice as we love the tree but cant have it destroying entrance.
