bermuda how much n per month

For Bermudagrass, the standard guideline is about 1 lb of actual nitrogen per 1,000 sq ft per month during the active growing season (late spring through summer, when the grass is green and growing).

Quick reference

Lawn type	Monthly N rate	Season-long total
Standard home lawn (common bermuda)	0.5–1 lb N / 1,000 sq ft	2–4 lb / 1,000 sq ft
Hybrid bermuda / higher quality	1 lb N / 1,000 sq ft	4–6 lb / 1,000 sq ft
Low-maintenance / unirrigated	~0.5 lb N / 1,000 sq ft	1–2 lb / 1,000 sq ft

Key points

• Only fertilize when bermuda is actively growing — roughly from green-up in spring (after the last frost, soil temps consistently above ~65°F) until ~30 days before your average first fall frost. Don't apply N to dormant (brown) bermuda.
• Never apply more than 1 lb of N per 1,000 sq ft in a single application of quick-release (soluble) fertilizer, or you risk burning the lawn. Split it if you want more.
• A 0.5 lb every 2 weeks schedule is gentler and gives more even color than 1 lb monthly.
• Stop N feeding ~4–6 weeks before your first expected frost so the grass can harden off for winter.

How to calculate your dose

To apply 1 lb N per 1,000 sq ft, divide 100 by the first number in the fertilizer's N-P-K ratio:

• A 16-4-8 product → 100 ÷ 16 ≈ 6.25 lb of product per 1,000 sq ft
• A 46-0-0 (urea) product → 100 ÷ 46 ≈ 2.2 lb of product per 1,000 sq ft

If you can tell me your region/state, whether the lawn is irrigated, and the grass quality you're after (basic vs. golf-course green), I can dial in a more precise monthly program and suggest specific products with sources.
