Centipede Grass Lawn Care Schedule

Timing: early March to mid-April

Warm-season turf begins breaking dormancy as soil temperatures reach about 55°F, but it isn't actively growing until the soil warms to roughly 65°F.

Do not scalp Centipede grass to bring it out of dormancy. The deep low spring reset is a bermuda and zoysia practice; on Centipede grass a scalp thins the stand rather than resetting it. Its own recommended height of 1–2″ is where its reserves and its shade and weed tolerance live, whether that number is high or low.

Rake or collect loose matted leaf; mechanical dethatching is a separate treatment requiring species-specific timing and recovery. A modest first cut a little lower than usual to clear dead leaf is fine on centipede — never below about 1″, never a scalp, and still within the one-third rule, so a lawn kept tall may need two cuts to get there; after that, mow at the normal height. Follow the one-third rule: never remove more than a third of the blade in one pass.

Don't fertilize until it's about 50% green and actively growing — roughly when soil temperatures hold above ~65°F.

Timing: mid-March to early April

Apply a pre-emergent herbicide as soil temperatures climb through the low 50s°F — before they reach the ~55°F at which crabgrass germinates — to stop summer weeds before they start. Whether a second pass is called for, how long after the first, and what the season's total may add up to are all set by the active ingredient and rate on your label, not by a general rule: some products are labeled for a split program and some are a single application for the year. Pick the product first, then read its split-application and maximum-annual-rate directions.

Timing: late April to mid-May

Make the first fertilizer application 2–4 weeks after full green-up, once the lawn is actively growing. Less is more with centipede: 1 lb of nitrogen per 1,000 sq ft per year is the standard target — go toward 2 lb only on sandy soils in high-rainfall areas, and treat 2 lb as the top of the planning range, since excess nitrogen is a well-known cause of centipede decline. Wait until the soil is consistently near 65°F before the first spring feeding rather than pushing it early. Reach for iron rather than extra nitrogen to green it up. A soil test matters here because centipede prefers an acidic pH (5.0–6.0).

Timing: early May to late June

Core-aerate during active growth to allow recovery; avoid aerating dormant or drought-stressed turf. Before dethatching, measure the layer: over about ½" warrants assessment, not automatic removal. Consider grass type, site conditions and symptoms, and follow local species and equipment guidance. For dethatching, ordinarily wait for full green-up and active growth with recovery time, including on St. Augustine and centipede. Oklahoma offers pre-green-up guidance; do not generalize it nationally. Confirm species, method and recovery conditions locally.

Timing: early June to mid-August

Summer is the warm-season growth peak. Less is more with centipede: 1 lb of nitrogen per 1,000 sq ft per year is the standard target — go toward 2 lb only on sandy soils in high-rainfall areas, and treat 2 lb as the top of the planning range, since excess nitrogen is a well-known cause of centipede decline. Wait until the soil is consistently near 65°F before the first spring feeding rather than pushing it early. Reach for iron rather than extra nitrogen to green it up. A soil test matters here because centipede prefers an acidic pH (5.0–6.0). Spread the annual budget across the season rather than applying it all at once.

Centipede's whole program finishes in August. Feeding it into autumn — or past its 2 lb annual budget at any point — is a well-known trigger for centipede decline, so there is no separate final feeding on this schedule.

Timing: early June to late August

Spot-treat broadleaf weeds during active growth, never on drought-stressed turf. Watch for insect and disease pressure in hot, humid weather and treat problem areas rather than the whole lawn.

Timing: early September to late October

Fall is the best time to take a soil test: lime or sulfur has the winter to react, and you go into spring with a real pH and fertility picture instead of guesswork. Send it to your state extension lab and tell them which grass you grow — the target pH is species-specific, and a lab that knows you have centipede reports against a different range than one assuming bluegrass.

Timing: mid-September to mid-October

A fall pre-emergent applied before soil cools below about 70°F controls winter annual weeds like Poa annua and henbit.

Timing: early November to late December

Wherever winter brings frost, expect a brown, dormant lawn from the first frost until spring green-up: hold off on fertilizer and pre-emergent, and give a light watering during extended winter drought to prevent desiccation. In the warmest, nearly frost-free areas (roughly USDA zone 10 — south Florida, coastal Southern California), the lawn often just slows down and stays partly green rather than going fully dormant; keep mowing and watering lightly as needed, and it can still use a little nitrogen or iron for winter color.
