What is the best way to remove dense forsythia to prepare for replanting. I have a 120' x 25' bank area (about 35% angle), that is covered with 7' tall forsythia. Customer wants it all removed and planted with junipers. Should I try to kill the forsythia first by spraying? I thought about renting a bobcat with 4 in 1 bucket to dig them out, but not sure if I could work that steep a bank. Any help in the way of suggestions would be appreciated.
