If there is bermuda mixed in the centipede, that means the centipede is either not suited to the soil, or the maintenance was not correct. Get a soil test done. You need to know nutrient levels and pH. Bermuda does not do well in acidic, poor soils. Conversely, centipede will not grow well in non acid soil that has too much phosphorus and calcium.
They who can give up essential liberty to obtain a little temporary safety, deserve neither liberty nor safety.
