How do you trim forsythia? I just did a pruning job for a customer which included the severe pruning of a couple rhodi's as well as trimming back some forsythia. The customer requested that I get the top of the forsythia... however that is pretty hard to do. There are 3 of them which are in question. They are each about 8 feet tall. 2 of them combined are 30 feet across and probably 50 feet in length. The other 1 isnt as bad. I have access to a stihl extended shaft pole trimmer, but that won't do me much good. I could also get a trimmer attachment for my HT-75, but that would be heavy as all heck. Not ready to spring the $120,000 for the new Hi-Ranger yet... so that is also out of the question.
