I'm having a couple of ash trees in my backyard pruned and the arborist that will be doing the work says to never "top" a trees. He says doing so will injure and perhaps kill the trees by exposing the fresh cuts to the hot Sacramento sun.
My trees are about 40 feet tall and he says the pruning job will consist of raising the canopy slightly, thinning branches smaller than 2 inches in diameter and removing (some) damaged, broken branches.
Does that sound like a reasonable plan? Is he right to never "top" a tree because doing so will at the very least, injure the tree?
Thank you,
Ed
