I want to prune and cut back branches on my Hemlock. the tree is getting .too wide.
How much of a Canadian Hemlock branch can you prune and still get growth on that branch??

Canadian hemlocks are tolerant of shearing to maintain a size. Don't remove more than 25% of the branch, or of the entire foliage in a one year period, is the rule of thumb for best management practices in pruning.
