Bermudagrass care calendar
Aggressive warm-season turf that greens up when soil holds 65°F. Loves heat, sun, and short mowing. Goes dormant (brown) with the first frost.
Mowing height
0.5"–1.5" (reel) · 1.5"–2.5" (rotary)
N per season
3–5 lb / 1,000 sq ft
Green-up
Soil ~65°F sustained
Dormancy
First hard frost
Jan
winter
Dormant — plan, don't spray.
- Soil testCheap in winter; sets the whole season.
- Sharpen mower bladeRagged tips brown out fast in summer.
Feb
winter
Late winter — pre-emergent prep.
- Order pre-emergentProdiamine or dithiopyr. Ready before soil hits 55°F.
- Skip fertilizerFeeding dormant bermuda feeds weeds instead.
Mar
spring
Pre-emergent window.
- Apply pre-emergentOnce soil 2" hits 55°F sustained 3+ days. Split app: half now, half in ~8 weeks.
- Scalp (optional)Drop mower 1 notch below normal to remove dead top growth once green-up starts.
Apr
spring
Green-up.
- First mow at target heightCut regularly — bermuda thickens with mowing.
- Post-emergent for winter weedsPoa, henbit, chickweed — hit before they seed.
- Wait on nitrogenFeed only after 100% green-up (no straw patches).
May
spring
Kick off feeding.
- First N application0.75–1 lb N / 1,000 sq ft. Balanced or slow-release.
- Second pre-emergent splitKeeps crabgrass suppressed into midsummer.
- Watch for spring dead spotCircular dead rings — note them, plan a fall fungicide.
Jun
summer
Prime growth.
- Feed monthly0.5–1 lb N / 1,000 sq ft. Iron for color without extra push.
- Mow tight and oftenEvery 4–5 days. Never remove >1/3 blade in one cut.
- Deep, infrequent water1" total per week including rain, in 1–2 sessions.
Jul
summer
Push hard.
- Continue NSlow-release preferred in heat.
- Spot-spray sedge & goosegrassSedgehammer for nutsedge; MSMA/quinclorac for goosegrass on warm turf only.
- PGR (optional)Primo Maxx to reduce clippings + tighten canopy in high-input lawns.
Aug
summer
Hold the line.
- FeedHalf rate if lawn is stressed from drought.
- Watch for army wormsSuddenly thin patches with chewed blades — Bifenthrin next mow.
Sep
fall
Last real push.
- Final NCut back — ~0.5 lb N. Too much late feed = winterkill risk.
- Fall pre-emergentProdiamine before soil drops to 70°F to block poa annua and winter weeds.
- Aerate + topdressOnly while bermuda is still growing hard — recovers in 2 weeks.
Oct
fall
Winter-weed prevention.
- Post-emergent if pre missedKill emerged poa/henbit while temps still allow bermuda recovery.
- Potassium (K) boost0.5–1 lb K / 1,000 sq ft strengthens winter hardiness.
- Stop NNo nitrogen from here on.
Nov
fall
Wind down.
- Raise mowing height 1 notchLast mow before dormancy.
- Rake leavesSmothered dormant bermuda struggles to green up.
Dec
winter
Dormant.
- NothingDon't fertilize. Don't spray. Rest.
Southern bermuda (zones 8b+) may green up 2–4 weeks earlier — trust soil temp, not the calendar.
