Birmingham guide · 2026 edition
If you live in the Birmingham metro and you want a month-by-month playbook for your lawn — what to do, what to skip, and when — this is your guide.
Most Birmingham lawn-care advice is written for “the South” generally, or for “warm-season grasses.” That misses the point. Birmingham has its own rhythm: it sits at the northern edge of Zone 8a, which means our growing season is longer than most of the rest of the country but shorter than coastal Alabama. False springs in February are normal. So are 95°F stretches in late August. Your lawn schedule needs to account for both.
This guide walks you through every month of 2026 — what your lawn is doing, what you should do, and (just as important) what you should NOT do. It assumes a warm-season grass — Bermuda, Zoysia, or Centipede — which covers the vast majority of Birmingham yards.

January — Cold and quiet
Your lawn is dormant. Bermuda is brown, Zoysia is straw-colored, Centipede looks dead but isn’t. Don’t panic.
What to do this month
- Get your mower serviced. Sharp blades make clean cuts; clean cuts heal faster. Most repair shops have zero wait in January.
- Check your soil pH. Birmingham’s red clay tends acidic (pH 4.5–6.0). If you haven’t tested in 3 years, send a sample to Alabama Cooperative Extension System (ACES). Results come back in 2 weeks — time enough to spread lime before spring growth if needed.
- Pick up debris. Leaves, sticks, kid toys — anything sitting on dormant grass risks smothering it once growth resumes.
What NOT to do this month
- Don’t fertilize. Dormant grass doesn’t absorb nitrogen — you’d just be feeding weeds.
- Don’t mow unless the lawn has actively grown since last fall (rare in Birmingham).
- Don’t apply pre-emergent yet — it’s too early, and you’ll lose effectiveness before crabgrass germination starts in March.
February — The danger month
February is when Birmingham homeowners get burned. We get warm spells — 75°F in mid-February isn’t unusual — and people race to the garden center for fertilizer. Don’t.
See our deeper guide on false spring in Birmingham for the full story.
What to do this month
- Apply your first pre-emergent. Mid-February (Valentine’s Day is the easy mnemonic) is the right window for spring weed control. Pre-emergents stop crabgrass and goosegrass before they germinate — they don’t kill mature weeds.
- Apply lime if your January soil test recommended it. Lime is slow-acting — applying in February gives it 2–3 months to work before peak growth.
- Sharpen mower blades. A second sharpening before peak season pays for itself.
What NOT to do this month
- Don’t fertilize. Even if your grass is green on top from a warm spell. The roots aren’t ready.
- Don’t scalp the lawn yet. Wait for mid-March at the earliest.
March — Wake-up call
Birmingham’s warm-season grasses start “greening up” — the visible color change as new growth pushes through last year’s dormant blades. This usually starts mid-March in most yards.
What to do this month
- Scalp Bermuda or Zoysia lawns (mid-March to early April). Scalping means cutting your lawn shorter than normal — down to about 1 inch — to remove the dead, dormant tops. This lets sunlight reach the soil and warms it faster, accelerating green-up. Don’t scalp Centipede or St. Augustine.
- Rake or bag the clippings. Scalping leaves a lot of debris. Bagging removes it; raking redistributes it.
- Soil temperatures hit ~55°F. Crabgrass starts germinating. Your February pre-emergent should still be active — but if you skipped it, applying now is much less effective.
What NOT to do this month
- Don’t apply fertilizer until the lawn is 50%+ green. Premature feeding wastes nitrogen on dormant grass.
- Don’t water deeply yet. Warm-season grasses go from dormant to active growth fastest when they’re slightly stressed for water.
April — The starting line
By mid-April, most Birmingham lawns are 80%+ green and growing. Time to fertilize and start regular mowing.
What to do this month
- Apply your first nitrogen application. A balanced slow-release fertilizer (something like 16-4-8) works for most Bermuda and Zoysia lawns. Avoid heavy applications — 0.5–1.0 lb of nitrogen per 1,000 sq ft is plenty.
- Begin weekly mowing. Keep Bermuda at 1.0–1.5 inches, Zoysia at 1.5–2.5 inches. Cool, dry mornings are ideal.
- Hand-pull any weeds you missed. A few young dandelions or chickweed are easier to pull now than to spray later.
May — Peak growth begins
Bermuda is now in its happiest state: warm nights, lots of sun, plenty of soil moisture. Growth is fastest in May–early June.
What to do this month
- Mow weekly without exception. Skipping a week now means cutting more than 1/3 of the blade at once, which stresses the grass.
- Apply a second light nitrogen feeding (late May). Half-rate (0.5 lb/1000 sq ft) keeps growth steady without forcing it.
- Watch for chinch bug damage on dry, sunny spots. Small straw-colored patches in dry weather are the early sign.
June — Heat builds
June in Birmingham averages mid-80s with regular afternoon thunderstorms. Lawns grow fast and recover from mowing fast.
What to do this month
- Mow at the right height. Cutting too short during the season opens the soil to weeds and dries roots. Bermuda 1.0–1.5 inches; Zoysia 1.5–2.5 inches; Centipede 2.0 inches.
- Water deeply once or twice per week. 1 inch total per week, applied in 1–2 sessions, beats daily shallow watering. Deep watering forces roots down.
- Time mowing for early morning. 7–10 AM is ideal: dew has dried, heat hasn’t peaked, grass blades are upright.
July — Summer survival
Birmingham’s hottest month. Bermuda thrives; Zoysia holds; Centipede may show stress. Watering and timing matter most this month.
What to do this month
- Don’t fertilize during heat waves. If your forecast shows a week of 95°F+, hold off — nitrogen during heat stress burns lawns.
- Watch for army worms. Late July through early September is peak season. Brown patches that spread quickly = army worms. Treat immediately or call a pro.
- Mow with a sharp blade, every time. Dull blades tear blade tips, which turn brown and look like drought stress. Sharpen every 3–4 mows in peak season.
August — Maintain, don’t push
Hot, dry stretches alternate with humid downpours. Survival mode for most lawns.
What to do this month
- Continue weekly mowing — but raise the cut by 1/4 to 1/2 inch during heat stress. Slightly taller grass shades the soil and reduces evaporation.
- Apply final nitrogen (early August). Light rate, slow-release. This is the last feeding of the year for most warm-season grasses.
- Stop watering wet lawns. Birmingham’s late-summer humidity + standing water = fungal diseases (brown patch, gray leaf spot).
September — Transition month
Days shorten, nighttime lows drop below 65°F. Growth slows. This is when winter prep starts.
What to do this month
- Apply your second pre-emergent (mid-September). This stops winter weeds (henbit, chickweed, annual bluegrass) before they germinate in October.
- Aerate if needed. Heavy traffic, compacted clay, or thin spots = aeration candidate. Late September is ideal for warm-season grasses; the new holes heal before dormancy.
- Stop fertilizing. Late-season nitrogen on warm-season grasses delays dormancy and weakens winter hardiness.
October — Last full month of growth
Bermuda growth slows noticeably. Cooler nights mean less heat stress but also less recovery.
What to do this month
- Continue mowing weekly or biweekly. Drop frequency as growth slows.
- Rake or mulch fallen leaves. Leaves smothering grass for 2+ weeks kill the blade underneath.
- Apply a potassium-only fertilizer if soil tests show low K. Potassium boosts winter hardiness. Don’t apply nitrogen.
November — Winding down
Most Birmingham lawns get hit with their first hard frost (28°F or below) in early-to-mid November. Grass goes dormant within days.
What to do this month
- Do your final mow. Cut slightly lower than your usual height — about 1 inch for Bermuda. Removes long blades that would mat down over winter.
- Clean up leaves thoroughly. No leaves left on the lawn through winter.
- Stop watering. Dormant grass doesn’t need it.
- Drain irrigation system if you have one. Birmingham winters can freeze pipes.
December — Rest
Your lawn is dormant. So can you be.
What to do this month
- Nothing. Really. Take the month off.
- If your soil test was old, schedule a winter test. Results come back in January.
