Bermuda Grass Annual Fertilization Schedule for North Texas

Bermuda grass is the dominant turf in North Texas for a reason: it handles 100-degree summers, recovers from drought, and spreads aggressively enough to fill bare spots on its own. But a Bermuda lawn only reaches its potential when it’s fed on a schedule that matches how this grass actually grows. Feed it too early in spring and you waste fertilizer. Feed it too late in fall and you push tender growth into the first freeze. Feed it right and you get the kind of dense, dark-green, weed-resistant turf that makes your lawn the best-looking one on the street. Here is the annual fertilization schedule we use for Bermuda lawns across Arlington and DFW — refined over nearly twenty years of local experience.

Understanding Bermuda’s Growth Cycle in North Texas

Bermuda is a warm-season grass that enters full dormancy in winter when soil temperatures drop below 50°F. In the Metroplex, that typically means dormancy from late November through February, with green-up starting in March and full active growth by April–May. Peak growth occurs June through August when air temperatures are highest. Then growth slows again in September–October as days shorten and soils cool toward dormancy.

This growth arc dictates everything about a sound fertilization program. Fertilizer applied during dormancy or before green-up is largely wasted — the grass can’t take it up efficiently, and nitrogen sits in the soil where it leaches or volatilizes. The goal is to time nitrogen delivery to match periods of active root uptake and shoot growth.

March: Pre-Emergent, Not Fertilizer

March is not a fertilization month for Bermuda in North Texas. It’s a pre-emergent month. While the lawn is still dormant or just starting to show green, soil temperatures in the 55–60°F range signal the window to apply prodiamine or pendimethalin to prevent crabgrass and goosegrass from germinating. Applying fertilizer alongside pre-emergent in March pushes nitrogen into soil the grass can’t yet utilize, while simultaneously wasting money and feeding any winter annual weeds still active in the turf.

Wait. The pre-emergent goes down in late February to mid-March. The fertilizer comes later.

April–May: Spring Starter Application

Once Bermuda has fully broken dormancy and daytime temperatures are consistently above 70°F — usually mid-April in Arlington — the first nitrogen application of the year is appropriate. At this stage Bermuda is actively growing new tillers and establishing root mass for the season ahead.

• Target rate: 0.75–1 lb of actual nitrogen per 1,000 sq ft.
• Product choice: A blended slow-release product (50%+ controlled-release nitrogen) to provide sustained feeding without burning tender new growth.
• Supplemental iron: A foliar iron application alongside or shortly after the nitrogen will deepen the green color dramatically without driving excessive shoot growth. Bermuda responds to iron faster than almost any warm-season grass.
• What to avoid: High-phosphorus products are unnecessary on established Bermuda in North Texas. Our clay soils retain phosphorus well and most established turf doesn’t need supplemental phosphate unless a soil test indicates deficiency.

June: Peak Season Feeding

June is the single most important fertilization month for Bermuda grass in North Texas. Soil temperatures are climbing into the 80s, Bermuda is in full metabolic overdrive, and nitrogen uptake efficiency is at its annual peak. This is not the month to skip or defer.

• Target rate: 1–1.5 lbs of actual nitrogen per 1,000 sq ft.
• Product choice: Professional-grade polymer-coated urea (PCU) releases at the rate Bermuda demands in summer heat. The temperature-activated release mechanism aligns with peak growth.
• Potassium: Including potassium (K) at this application helps build the cellular strength Bermuda needs to tolerate heat stress. A 3-1-2 or 4-1-2 N-P-K ratio works well for summer feeding.

July–Early August: Mid-Summer Application (Optional but Valuable)

If you’re running a higher-intensity program and targeting maximum density and color, a mid-summer application in late July keeps nitrogen available through August when Bermuda is still actively growing but the June application’s controlled-release fraction may be winding down.

• Target rate: 0.5–0.75 lb of actual nitrogen per 1,000 sq ft — lighter than June.
• Timing caution: Do not apply granular fertilizer during extreme heat stress (multiple days over 105°F without rain). Wait for cooler conditions or a rain event to water granules in and reduce burn risk.
• Liquid options: A liquid nitrogen application at this time of year — diluted and applied in early morning — can be a safer alternative during the hottest periods.

September: Fall Potassium Application

September marks the transition away from growth-pushing nitrogen and toward hardening applications. As days shorten and Bermuda starts slowing growth in preparation for dormancy, a potassium-heavy application builds cell wall strength, improves cold tolerance, and supports the root system through winter.

• Target rate: Low nitrogen (0.25–0.5 lb actual N per 1,000 sq ft), higher potassium (0.5–1 lb K&sub2;O per 1,000 sq ft).
• Soil amendment: If a soil test shows pH above 7.5 (common in Tarrant County), a September sulfur application alongside potassium begins lowering pH ahead of the next growing season.

September is also the window for fall pre-emergent to block Poa annua and cool-season grassy weeds from establishing for winter. Our weed control and fertilizer services page explains how we time these applications alongside fertilization.

October–November: No Fertilizer — Broadleaf Weed Control

Once October arrives and Bermuda is transitioning toward dormancy, fertilization is done for the year. Pushing nitrogen in October or November delays dormancy, leaves tender growth vulnerable to early freezes, and can actually weaken the lawn’s spring green-up by depleting carbohydrate reserves.

October–November is prime time for liquid broadleaf herbicide applications targeting clover, dandelion, chickweed, and henbit as they germinate in cooling soils. These weeds are most vulnerable when young and actively growing. Treating them in fall prevents the massive seed bank that drives spring weed pressure. This is why the best-looking Bermuda lawns next April are the ones that got solid fall weed control the October before.

Annual Nitrogen Budget for North Texas Bermuda

A well-managed Bermuda lawn in North Texas should receive 3–5 lbs of actual nitrogen per 1,000 sq ft per year, split across the applications above. Under-feeding produces a thin, pale lawn that loses ground to weeds. Over-feeding with quick-release nitrogen drives disease pressure and leaches nitrogen into groundwater. The middle path — consistent, calibrated, season-timed applications with controlled-release products — is what produces the lawns people stop to look at. Our previous post on controlled-release fertilizer technology and polymer-coated products for DFW soil goes deeper on why product quality matters as much as timing.
