Bermuda grass is invading my Kentucky Blue? Any solutions that don't involve Roundup?
I've heard of using asphalt shingles as a barrier between grass and flower beds (just dig a trench and bury a line of shingles, may not be pretty but it's effective) and that should stop any more grass from spreading but as for the existing grass you may be forced to either use RoundUp or chop it out and re-seed. I'm not sure of any chemical or other control method that targets Bermuda grass specifically.
