I've been told that severly pruining mature hardwood trees such as oaks and maples will damage their rooth systems. Is this true and if so is it really that significant?
Re: Tree Pruning
Severely pruning (topping) a tree is not the thing to do for the health of a tree. I don't think it damages the roots, but in maples especially, it promotes the growth of watersprout branches that grow quickly and make the tree more dense and possibly more prone to blowing over. The watersprouts are typically weak & subject to splitting later. I bet some other forum members more versed in tree science will have better explanations on why not to top a tree.
