Small trees destroying fence
I'm losing the battle with dozens of saplings that come up every spring from the neighbor's hackberry and especially our black walnut. Every year I take a hacksaw and cut the small trunks and spray a little Roundup. That usually stops the growth, but every year there are more plus I hate using Roundup. These grow through and around the chain link fence. We tried digging them up and couldn't, too deep, too much part of the big trees. What can we do? Thank you.
