For about a year now, I've been trying to get rid of a ton of weeds. I'm not exactly sure what they are, but they aren't easy to get rid of, as they grow pretty quick and seed everywhere. I've trying pulling up by the roots, digging up the roots, making rock beds with landscaping paper over them, and finally weed killer. Nothing works. And after weeding, they're back to 3/4 inches tall after a week. I have no clue how to get rid of these things!
