Best Fertilizer for Bermuda Grass

Quick Answer

Bermuda grass is a heavy nitrogen feeder — use a high-nitrogen fertilizer (roughly a 4-1-2 or 3-1-2 N-P-K ratio) applied every 4-6 weeks through its active growing season, late spring through summer.

Why Bermuda Grass Needs More Nitrogen Than Most Lawns

Bermuda grass grows aggressively during its active season — that's part of why it's prized for durability and fast recovery from damage, but it also means it uses up available soil nitrogen faster than slower-growing grass types. Under-feeding shows up as thinning, pale color, and reduced density that lets weeds establish more easily.

Recommended N-P-K Ratio

A high-nitrogen ratio such as 4-1-2 or 3-1-2 fits most established Bermuda lawns, though a soil test is the only reliable way to confirm your phosphorus and potassium levels rather than guessing. See our full nitrogen fertilizer guide for how much actual nitrogen that translates to per application.

New Bermuda lawn or sod?

Newly seeded or sodded Bermuda benefits from a starter fertilizer higher in phosphorus for root establishment before switching to a high-nitrogen maintenance schedule once established.

Application Schedule

See our full Bermuda grass care guide for mowing and watering to pair with this schedule.

Frequently Asked Questions

A high-nitrogen ratio like 4-1-2 or 3-1-2 works well for most established Bermuda lawns, though a soil test is the only way to confirm your phosphorus and potassium needs precisely.
