Started several years ago from a 1 gallon pot divided 4 ways, they are now growing together and looking pretty good, on a rough, steep, rocky and ugly bank. Every year I snip the redbud sprouts off at the ground and every year they show back up again. The tree that seeded this area has been gone for years. I can't spray to kill them without getting the poison on the bamboo. Suggestions appreciated, I'm tired of climbing that bank so often the cut the junk.

Thanks, Matt
