Done correctly, by professionals, pollarding or coppicing will not kill your tree. … Tree topping can also shock the tree, leading to erratic growth or sudden death.
Can you Pollard a mature tree?
A tree which has been allowed to grow without being cut as a pollard (or coppice stool) is called a maiden or maiden tree. Pollarding older trees may result in the death of the tree, especially if there are no branches below the cut, or the tree is of an inappropriate species.
How long does it take a tree to grow after pollarding?
Older pollards often become hollow, so it can be difficult to determine age accurately. Pollards tend to grow slowly, with denser growth-rings in the years immediately after cutting.
