Centipede Aeration & Dethatching
Aeration: Core aeration in late spring to early summer (active growing season only). Centipede benefits from aeration because its shallow roots are sensitive to compaction. Use CORE PULLING aerator — NOT spike units. Do NOT aerate when dormant. Post-aeration: apply HUMICHAR into holes to improve sandy soils. Dethatching: Centipede produces LESS thatch than Bermuda. Only dethatch if thatch exceeds 0.5 inches. Use a BLADED dethatcher — NOT a prong-type dethatcher, which damages centipede's shallow stolons. Best time: late spring when centipede is actively growing. Aggressive dethatching can severely damage centipede — be gentle.
Frequently Asked Questions
When should I aerate centipede?
Aerate centipede in late spring to early summer when it is actively growing. Centipede recovers slowly, so aerating during its strongest growth period gives it the best chance to fill in the holes.
How often should I aerate centipede?
Every 2-3 years is sufficient for most centipede lawns unless you have heavy clay or compacted soil. Over-aerating stresses centipede's shallow root system and slow-growing stolons.
Does centipede need dethatching?
Only if thatch exceeds half an inch. Centipede produces less thatch than bermuda because it grows more slowly. Over-dethatching damages centipede and recovery is very slow. Check before you dethatch.
Should I topdress centipede after aerating?
A light topdressing of sand or compost after aeration can be beneficial. Apply very thin layers — no more than a quarter inch — because centipede grows slowly and thick topdressing can smother it.
