We have a "Jacquemontii" planted approx. 16 foot from the back of our house. It is planted in a raised bed 4 foot from a boundary wall. The raised brick bed (6 inches in height) is underpinned by a small retaining wall ( 3 inches in height) which has been cracked by one of the tree's roots (8 inches below ground surface). This root is 3 inches in diameter and since it has split the wall it is lifting it up off the ground.1. Can I sever this root to stop it doing more damage? 2. If so will it kill the tree? 3. Is this type of tree too near the house and likely to do more damage?
I have an Acer brilliantissimum that I planted 6 years ago. Unfortunately not knowing at the time I planted it too near a wall. Can I move it and if so when is the best time of year? Secondly does it need to be far from the house as I understand this is a small tree?
