Bermuda Grass Lawn Care Schedule — USDA Zone 9

Spring pre-emergent (crabgrass)

Apply a pre-emergent herbicide as soil temperatures approach 55°F to stop crabgrass and other summer weeds before they germinate. A second application 6–8 weeks later extends control through the season.

⚠️Don't apply a pre-emergent if you plan to seed — it blocks grass seed too. Always read and follow the product label — it is the legal authority on rates, timing, and safety. These windows are regional estimates, not a prescription; defer to the label and your local extension office.

Spring green-up & first mow

As soil temperatures reach about 55°F the lawn breaks dormancy and greens up. Once it's about half green, mow low to clear dormant material and let sunlight reach the crowns. Don't fertilize until it's at least 80% green.

First feeding

Make the first fertilizer application 2–4 weeks after full green-up, once the lawn is actively growing. Bermuda is a heavy feeder during its summer growth peak. Budget about 3–5 lbs of nitrogen per 1,000 sq ft across the whole season, split into several feedings every 4–6 weeks from full green-up until about 6 weeks before your first expected frost.

⚠️Bermuda's appetite for nitrogen makes it easy to over-apply. Never exceed ~1 lb of nitrogen per 1,000 sq ft in a single feeding, and stop nitrogen about 6 weeks before frost so you don't push tender growth into winter. Always read and follow the product label — it is the legal authority on rates, timing, and safety. These windows are regional estimates, not a prescription; defer to the label and your local extension office.

Aeration & dethatching

Core-aerate (and dethatch if the thatch layer is over about ½") during the peak growing season, when warm-season turf recovers fastest. Avoid aerating dormant or drought-stressed turf.

Summer feeding program

Summer is the warm-season growth peak. Bermuda is a heavy feeder during its summer growth peak. Budget about 3–5 lbs of nitrogen per 1,000 sq ft across the whole season, split into several feedings every 4–6 weeks from full green-up until about 6 weeks before your first expected frost. Spread the annual budget across the season rather than applying it all at once.

⚠️Never exceed ~1 lb of nitrogen per 1,000 sq ft in a single feeding. Always read and follow the product label — it is the legal authority on rates, timing, and safety. These windows are regional estimates, not a prescription; defer to the label and your local extension office.

Summer weed & pest watch

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.

Final feeding & soil test

Give a final feeding in early fall, then stop nitrogen — late-season nitrogen pushes tender growth into frost. Fall is also the best time to take a soil test so amendments are ready before spring.

⚠️Stop nitrogen about 6 weeks before your first expected frost. Always read and follow the product label — it is the legal authority on rates, timing, and safety. These windows are regional estimates, not a prescription; defer to the label and your local extension office.

Fall pre-emergent (winter weeds)

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

⚠️Always read and follow the product label — it is the legal authority on rates, timing, and safety. These windows are regional estimates, not a prescription; defer to the label and your local extension office.

Optional winter overseed

For green color over winter dormancy, you can overseed with perennial ryegrass once soil cools below about 70°F. It's optional and adds maintenance — skip it if you're happy with a dormant, straw-colored lawn.

⚠️If you overseed, do not apply a fall pre-emergent — it will stop the ryegrass from germinating.

Winter dormancy

Expect a brown, dormant lawn from first frost until spring green-up. Hold off on fertilizer and pre-emergent. A light watering during extended winter drought helps prevent desiccation.
