Native prairie grass built for the Great Plains. Extremely low water and fertilizer needs. The most drought-tolerant lawn grass in North America.
About Buffalo Grass
Scientific name: Bouteloua dactyloides (formerly Buchloë dactyloides)
Origin: Native to the Great Plains of North America
Buffalo grass is the only major turfgrass native to North America, evolving on the shortgrass prairies of the Great Plains where annual rainfall averages 12 to 25 inches. Its blue-green blades reach only 4 to 8 inches when unmowed, and a mature stand needs only one or two mowings per season. Buffalo grass spreads slowly via stolons rather than aggressive rhizomes, producing an open turf that works well as a low-input native lawn but does not form the dense carpet of Bermuda or Zoysia. It is dioecious, meaning male and female plants are separate, modern improved cultivars like UC Verde, Legacy, and Prestige are female-only selections that eliminate the unsightly male flower spikes and produce a more uniform appearance. Buffalo grass thrives in heavy clay and silty soils typical of the Plains states, requires less than 1 pound of nitrogen per 1,000 square feet annually, and survives drought that would kill Kentucky Bluegrass or even Bermuda. Its weak shade tolerance, slow establishment, and dormant brown color from October through April are the main reasons it has not become a national lawn grass despite its sustainability credentials.
Buffalo Grass Growing Zones
Buffalo Grass performs best in USDA hardiness zones 5b, 6a, 6b, 7a, 7b. These zones provide the right combination of temperature range, growing season length, and winter conditions for Buffalo Grass to thrive.
As a warm-season grass, Buffalo Grass enters dormancy when soil temperatures drop below 55°F and actively grows when temperatures are between 80°F and 95°F. Planting outside its recommended zones may result in winter kill or poor summer performance.

Watering Buffalo Grass
Buffalo Grass has the lowest water requirement of any common North American lawn grass, often surviving entirely on natural rainfall in its Great Plains range. Established lawns need only 12 to 20 inches of water per year, much of which falls as natural precipitation. When irrigation is needed during severe drought, apply 1 inch every 3 to 4 weeks in a single deep session. Overwatering Buffalo Grass is the single fastest way to thin it out: excess moisture encourages cool-season weeds (especially crabgrass and Bermuda) to invade the open turf and out-compete it. New Buffalo Grass plantings need consistent surface moisture for the first 4 to 6 weeks (water lightly daily), then transition rapidly to deep, infrequent irrigation through the end of the first season. By year two, healthy Buffalo Grass lawns in the Plains states often need no supplemental water at all from rain-only watering systems.
Fertilizing Buffalo Grass
Buffalo Grass needs the lowest fertilization of any common lawn grass, 0 to 1 pound of nitrogen per 1,000 square feet per year. Many established lawns thrive on no supplemental fertilization at all, particularly in the Plains states where soils retain adequate fertility from native organic matter and grass clipping return. When fertilization is used, apply a single 1-pound application of nitrogen in mid-June (after full green-up and before peak summer heat). Avoid spring fertilization, it pushes early top growth at the expense of root development and gives invasive cool-season weeds a competitive boost. Skip fall fertilization entirely; Buffalo Grass enters dormancy by October and cannot use additional nitrogen at that point. Phosphorus and potassium are rarely needed unless a soil test shows specific deficiencies. The single biggest fertility mistake on Buffalo Grass lawns is treating them like Bermuda, even moderate Bermuda fertilization rates will weaken Buffalo Grass and allow Bermuda or crabgrass to invade.
Soil Preparation and Site Selection for Buffalo Grass
Buffalo Grass is naturally adapted to the heavy clay and silty loam soils of the Great Plains, with optimal performance in pH ranges from 6.5 to 8.0 (more alkaline-tolerant than any other common lawn grass). The species struggles in sandy soils that drain too fast and in acidic soils more typical of the Eastern US, it is the wrong choice for the Southeast or Pacific Northwest. Site selection requires full sun (7+ hours minimum) and avoidance of irrigated zones (Buffalo Grass thins in wet conditions). The native Plains soil profile of well-drained clay over clay subsoil is ideal; sandy or compacted soils need amendment with topsoil or compost before establishment.
How to Establish a Buffalo Grass Lawn
Buffalo Grass is most reliably established from plugs ($0.20 to $0.40 each, planted on 12-inch centers with full coverage in 1 to 2 seasons) or female-only treated seed (4 to 6 pounds per 1,000 sq ft). The treated seed is hulled and scarified to break the natural dormancy that prevents most untreated Buffalo Grass seed from germinating. Plant plugs or seed in late spring (May or June) when soil reaches 70°F. Sod is increasingly available for premium cultivars (UC Verde, Legacy) at $0.80 to $1.20 per square foot, providing immediate coverage but at significant cost. Apply pre-emergent herbicide (prodiamine, not pendimethalin) the season before establishment to reduce weed pressure during the slow Buffalo Grass establishment period.
Seasonal Care Calendar for Buffalo Grass
Spring
March-May. Wait for full green-up (typically May in most of the range) before any mowing or fertilization. Apply pre-emergent (prodiamine) in mid-March. Once fully green, light mow at 2 to 3 inches. Skip spring fertilization entirely. Spot-treat invasive Bermuda or broadleaf weeds aggressively before they establish.
Summer
June-August. Mow every 2 to 3 weeks at 2 to 3 inches (or leave unmowed for native look at 4 to 8 inches). Optional single nitrogen application in mid-June (1 pound of N per 1,000 sq ft) for lawns wanting darker color. Skip irrigation entirely in normal rainfall years. During severe drought, apply 1 inch every 3 to 4 weeks.
Fall
September-November. Reduce mowing to every 4 weeks as growth slows dramatically. Final mow at 3 inches before dormancy. Skip all fall fertilization. Buffalo Grass goes dormant earlier than Bermuda, typically by mid-October in Plains states.
Winter
December-February. Buffalo Grass is dormant for 5 to 6 months, turning straw-tan. No maintenance needed. The dormant tan color is the main aesthetic objection homeowners raise to Buffalo Grass, accept it as part of the species' low-maintenance package.
Common Problems with Buffalo Grass
Slow Establishment
Buffalo Grass plugs and seed take 1 to 2 full growing seasons to fill in completely, leaving gaps where weeds can establish.
Solution: Plant treated (hulled and scarified) seed at 4 to 6 pounds per 1,000 square feet, or plugs on 12-inch centers. Apply pre-emergent herbicide (prodiamine, not pendimethalin) the season before seeding to reduce weed pressure during establishment.
Buffalograss Mealybug
Cottony white masses at the base of stems caused by Tridiscus sporoboli, leading to thinning and yellowing in patches.
Solution: Apply systemic insecticide (imidacloprid) in early summer when nymphs are active. Healthy, well-watered Buffalo Grass tolerates light mealybug pressure without intervention; chemical control is needed only for heavy infestations.
Weed Invasion in Open Turf
Buffalo Grass forms an open turf that allows broadleaf weeds and invasive grasses (especially Bermuda) to establish in gaps.
Solution: Spot-treat broadleaf weeds with selective herbicides labeled for Buffalo Grass (2,4-D and triclopyr are safe at low rates). Maintain mowing height at 2 to 3 inches to allow Buffalo Grass to compete; never scalp it.

FAQ, Buffalo Grass Common Questions
Is Buffalo Grass a good lawn grass?
Buffalo Grass (Bouteloua dactyloides) is excellent for low-maintenance lawns in the Great Plains and Central US (Zones 3 through 9, dry climates). It needs minimal water (12 to 15 inches of rain per year), little or no fertilization, and mowing only 3 to 4 times per season. It performs poorly in humid climates east of the Mississippi or in heavily shaded lawns.
Does Buffalo Grass stay green all year?
No, Buffalo Grass is a warm-season grass that goes dormant (tan or straw colored) from first frost through late spring. In Zone 5 to 6, this dormancy period is 5 to 6 months. In Zone 8 to 9 (Texas, Oklahoma), dormancy is shorter (3 to 4 months). This is normal and expected for the species.
Where does Buffalo Grass grow best in the US?
The Great Plains from Montana south through Nebraska, Kansas, Oklahoma, and Texas, the native range of Buffalo Grass. It also performs well in dry parts of Colorado, Wyoming, and the high desert Southwest. It struggles in the humid Southeast, Pacific Northwest, and northeastern states.
How much water does Buffalo Grass need?
Established Buffalo Grass lawns need as little as 12 to 15 inches of water per year, primarily from natural rainfall in the Great Plains. Supplemental irrigation should be minimal: overwatering encourages weeds and weakens the grass. In severe drought, deep watering every 3 to 4 weeks is sufficient to prevent permanent damage.
How do I establish a Buffalo Grass lawn?
Two options: plugs (fastest and most reliable) or seed (slower, lower cost). Plant plugs or seed in late spring (May or June) when soil reaches 70°F. Use treated seed (hulled and scarified) for faster germination. Keep moist for the first 3 to 4 weeks; once established, reduce watering aggressively. Expect full coverage in the first full growing season.
