I am honestly not sure, I am not nearly as knowledgeable as you guys are. From my feeble knowledge, I would guess Bermuda would beat out Centipede easily. So there is really no point in trying to stop the Bermuda.
None of my neighbors have Bermuda, how would this have taken hold so well here? Can I overseed the rest of my lawn that is mainly Centipede to help the Bermuda along?
