The infamous chameleon plant, it is a rapidly spreading creeper. In need to know how to kill it. I have tried various weed killers and no luck. I tried the concentreated Roundup on the chameleon and that just made it angry. I spread 3 layers of plastic over the ground where they live and they pop up around the edges. Does drowning/overwatering kill it? Should i use liquid nitrogen? Does acidifying the soil damage the chameleon? How about a base? If so, tell me what will be the most effective.
