Centipede Grass Decline: Builder's Trash or Natural Cycle?

Mike in GA: centipede sod replaced fescue twice, now failing again. Restore by sodding or sprigging. Builder's trash possible—usually front yard, causes discoloration/stunting, not total death. Soil test (pH 6.5 last year). Check for patterns.

Centipede is sensitive—fertilize lightly, mow high, water deep.
