Warm-season grass
Buffalograss Lawn Care Schedule
Buffalograss is a native warm-season grass of the North American plains, prized as the lowest-input real lawn there is: once established it needs very little water, fertilizer, or mowing. It is fine-textured and blue-green, spreads by stolons, and is unusually cold-hardy for a warm-season grass — but it wants full sun and a drier climate, and it thins out in shade, under heavy traffic, or in the humid Southeast.

Key care windows
Timing windows are flexible (early / mid / late) and tuned to a typical transition-zone season — soil temperature and your local weather should always have the final say.
Spring pre-emergent (crabgrass)
Apply a pre-emergent herbicide as soil temperatures climb through the low 50s°F — before they reach the ~55°F at which crabgrass germinates — to stop summer weeds before they start. A second application 6–8 weeks later extends control through the season.
Don't apply a pre-emergent if you plan to seed — it blocks grass seed too. Always read and follow the product label — it is the legal authority on rates, timing, and safety. These windows are regional estimates, not a prescription; defer to the label and your local extension office.
Spring green-up & first mow
Warm-season turf begins breaking dormancy as soil temperatures reach about 55°F, but it isn't actively growing until the soil warms to roughly 65°F. Once it's about half green, mow low to clear dormant material and let sunlight reach the crowns. Don't fertilize until it's at least 80% green and growing.
First feeding
Make the first fertilizer application 2–4 weeks after full green-up, once the lawn is actively growing. Less is more — about 1–2 lbs of nitrogen per 1,000 sq ft per year is plenty, and many buffalograss lawns get by on even less. Excess nitrogen mostly feeds weeds and forces mowing the grass does not need.
Buffalograss thrives on neglect — the biggest risk is over-caring for it. Keep nitrogen low (at or below ~1 lb per 1,000 sq ft per feeding) and do not overwater; both just invite weeds. Always read and follow the product label — it is the legal authority on rates, timing, and safety. These windows are regional estimates, not a prescription; defer to the label and your local extension office.
Aeration & dethatching
Core-aerate (and dethatch if the thatch layer is over about ½") during the peak growing season, when warm-season turf recovers fastest. Avoid aerating dormant or drought-stressed turf.
Summer feeding program
Summer is the warm-season growth peak. Less is more — about 1–2 lbs of nitrogen per 1,000 sq ft per year is plenty, and many buffalograss lawns get by on even less. Excess nitrogen mostly feeds weeds and forces mowing the grass does not need. Spread the annual budget across the season rather than applying it all at once.
Never exceed ~1 lb of nitrogen per 1,000 sq ft in a single feeding. Always read and follow the product label — it is the legal authority on rates, timing, and safety. These windows are regional estimates, not a prescription; defer to the label and your local extension office.
Summer weed & pest watch
Spot-treat broadleaf weeds during active growth, never on drought-stressed turf. Watch for insect and disease pressure in hot, humid weather and treat problem areas rather than the whole lawn.
Final feeding & soil test
Give a final feeding in early fall, then stop nitrogen — late-season nitrogen pushes tender growth into frost. Fall is also the best time to take a soil test so amendments are ready before spring.
Stop nitrogen about 6 weeks before your first expected frost. Always read and follow the product label — it is the legal authority on rates, timing, and safety. These windows are regional estimates, not a prescription; defer to the label and your local extension office.
Fall pre-emergent (winter weeds)
A fall pre-emergent applied before soil cools below about 70°F controls winter annual weeds like Poa annua and henbit.
Always read and follow the product label — it is the legal authority on rates, timing, and safety. These windows are regional estimates, not a prescription; defer to the label and your local extension office.
Winter dormancy
Expect a brown, dormant lawn from first frost until spring green-up. Hold off on fertilizer and pre-emergent. A light watering during extended winter drought helps prevent desiccation.

Buffalograss care guide
Mowing
Buffalograss can be mowed at 2–3" or left unmowed for a soft, informal meadow look — one of its main appeals. It grows slowly, so you will mow infrequently; mowing too often or too short mainly invites weeds without helping the stand.
Watering
Buffalograss is one of the most drought-tolerant lawns there is and needs far less water than most turf — often well under 1" per week once established. Overwatering is the classic mistake: it encourages weeds and defeats the whole low-input point of the grass.
Fertilizing
Less is more — about 1–2 lbs of nitrogen per 1,000 sq ft per year is plenty, and many buffalograss lawns get by on even less. Excess nitrogen mostly feeds weeds and forces mowing the grass does not need.
Weed control
Buffalograss is slow to close in, so weeds are the main challenge, especially in the first couple of seasons. Use a spring pre-emergent to keep annual weeds out and spot-treat broadleaf escapes with products labeled for buffalograss — it is sensitive to some herbicides.
Strengths
- Exceptional drought tolerance — a genuine low-water lawn
- Very low fertilizer and mowing needs
- Native and cold-hardy for a warm-season grass
Watch out for
- Needs full sun — thins badly in shade
- Struggles in humid climates and on heavy, wet soils
- Slow to recover from heavy traffic; weeds invade thin stands

A starting point — your plan adjusts to your yard
This Buffalograss schedule is a research-based template for your grass type. Your lawn is one of a kind, though: the right timing and amounts also depend on your soil test, sun and shade, irrigation, lawn size, and the goals you set — a low-input yard, the deepest possible color, or just crowding out weeds. YardLedger takes this template and adjusts it to your yard's specific needs, then keeps refining it from the history of what you've actually done and how the lawn responded — so every recommendation gets more personal over time.
Safety first
Buffalograss thrives on neglect — the biggest risk is over-caring for it. Keep nitrogen low (at or below ~1 lb per 1,000 sq ft per feeding) and do not overwater; both just invite weeds.
Always read and follow the product label — it is the legal authority on rates, timing, and safety. These windows are regional estimates, not a prescription; defer to the label and your local extension office.
