I'm tring to rid my yards of Bahaia. I've given up on the backyard until next year (its almost all Bahaia) and concentrating on the front yards. I'm dethatching down to soil, then planting a Centipede/carpetgrass mix. I'm doing it a few patches at a time. I have about a 10 X 30 strip that is Bahaia. Is Roundup, followed by stripping to soil and reseeding with centipede the best way to go? I'm open to suggestions. Also, is roundup the best way to deal with small patches of bahaia? I'd really like to get the centipede running and growing again.
