OK, almost everyone here is going to start hissing & booing at me, but I need some help. I have a small section of my yard, probably only 5-7' long and about 12" wide, that is overgrown with these hens & chicks. I'm not one for succulents, so I really don't want them. I ignore them for the most part, never water them, NEVER feed them, but they just keep growing! They've taken over my hollyhocks and they just keep a'creeping along. How on earth do I get rid of them? I've dug them out, but they just keep coming back! I figured that they wouldn't survive the cold unprotected, but they seem to thrive on less-than-good care. help? I hate using chemicals if I can avoid it... Don't ask me what kind they are as I have NO idea. I didn't plant them, they're volunteers from the neighbor behind me & the neighbor doesn't know what they are as they planted them like 20 years ago.
