I have a customer who wants me to cut back some enormous Rhododendrons. They are about 15 feet high and he wants me to cut about 5 feet or so off of them. Will they be able to survive this harsh of a pruning? Any suggestions or tips to insure they survive? I also have two dwarf blue spruce trees that need to come out stump and all. They have really thick trunks (about a foot wide), any suggestions on how to get these out of the ground. They are about 5 feet tall. I was thinking about chaining them to my F-250 and ripping them out of the ground. Thanks for any help.
