I received a call from a gentleman today and he wants me to trim two crab apple trees and straighten them out because they are starting to lean a little. Now i know how much to charge for the trimming but i have never charged someone yet for straightening out their trees. Like i said there are two crab apple trees about 15-20' tall, about 6-8" thick at the base and are starting to lean. What do you guys think? Thank you!
