Response from Tree Resource
Good tree work is dependent on a clear objective, identifying the proper type of pruning (thinning, reduction, etc.), and the right amount of pruning. The green maples the member is referring to have had an excessive amount of thinning in their history which has increased the likelihood of heavy rain or snow bending and breaking the branches. Our pruning specification, which the member agreed to, is as follows: “Reduction pruning of large ‘green’ maple in the back yard. GOAL is to prune on the ends of long stems to reduce the leverage in case of heavy snow or wind. No more than 15% live material should be removed.” Our arborists did exactly so. We tried multiple times to get in contact with the member as a follow-up to help them understand the difference between good and excessive pruning. For anyone reading this review, please understand that when we encounter a tree that has had excessive pruning done to it in the past, we cannot miraculously fix it by pruning a lot more of its branches. That is why our specifications have dosage limits on them. We can and do recommend minor pruning in just the right places on the tree to encourage growth of material that will benefit the tree in the future, but if your trees have been mal-pruned before, it will probably be a multi-season process to restore them to a natural growth habit.
