Buffalo Grass for Missouri: The Low-Maintenance Native Lawn Alternative

Buffalo grass is Missouri’s only native lawn grass. Before European settlers planted tall fescue and Kentucky bluegrass, the prairies of St. Charles County were covered in Buffalo grass — a short, drought-tolerant warm-season grass that survived on whatever rain fell and needed little else. Today, Buffalo grass is experiencing a resurgence among homeowners who want a low-maintenance, eco-friendly lawn that cuts water bills and mowing time in half. This guide covers everything you need to know about establishing and caring for a Buffalo grass lawn in St. Charles County.

What Is Buffalo Grass?

Buffalo grass (Bouteloua dactyloides) is a warm-season perennial grass native to the Great Plains, including Missouri. It is the only grass native to North America that is widely used as a lawn turf. Unlike every other grass in this guide series, Buffalo grass did not arrive from Europe or Asia — it evolved here, adapted to Missouri’s hot summers, periodic droughts, and clay soils.

Characteristic	Buffalo Grass	Tall Fescue (Missouri Standard)
Type	Warm-season, native	Cool-season, introduced
Water needs	Very low (0.5 inch/month in summer)	Moderate (1-1.5 inches/week)
Mowing frequency	Every 2-3 weeks in summer	Weekly in spring/fall
Mowing height	2-3 inches	3-4 inches
Fertilizer needs	Very low (0-1 lb N/year)	Moderate (2-4 lbs N/year)
Foot traffic	Low	Good
Winter color	Dormant tan (October–April)	Semi-dormant green-gray
Establishment speed	Slow (from seed)	Fast (seed or sod)

Why It Has Two Names

The grass was known for decades as “Buffalo grass” (one word, two L’s, a common spelling variant) because it was the primary forage for the American bison that once roamed Missouri’s prairies. Botanists now classify it as Buchloe dactyloides (the old name) or Bouteloua dactyloides (the updated classification), but almost everyone — seed companies, extension offices, and homeowners — still calls it Buffalo grass.

Why Choose Buffalo Grass in St. Charles County?

Buffalo grass solves the three biggest problems Missouri homeowners face with traditional lawns: water bills, mowing time, and fertilizer costs.

Water Savings

A tall fescue lawn in St. Charles County needs about 1 inch of water per week during summer — that is roughly 620 gallons per 1,000 square feet. A Buffalo grass lawn of the same size needs 2-3 inches of water per month during summer, and it can go 4-6 weeks without any water at all by going dormant. For a 5,000 square foot lawn, switching from tall fescue to Buffalo grass saves approximately 10,000 gallons of water per summer.

Mowing Reduction

Buffalo grass naturally grows to 4-6 inches tall and looks best mowed at 2-3 inches. During the summer growing season, mow every 2-3 weeks instead of every 5-7 days. From October through April, Buffalo grass is dormant and needs no mowing at all. That works out to roughly 10-12 mows per year versus 30-35 for tall fescue.

Fertilizer Elimination

Buffalo grass evolved on the Great Plains, where nitrogen was naturally scarce. It is adapted to low-fertility soil and actually grows worse if over-fertilized. Most Buffalo grass lawns need zero nitrogen fertilizer. If you do fertilize, 0.5 to 1 lb of nitrogen per 1,000 sq ft per year is the maximum.

Environmental Benefits

• No chemical inputs needed. Buffalo grass resists most pests and diseases naturally.
• Deep root system. Buffalo grass roots reach 4-6 feet deep — compared to 2-3 feet for tall fescue — making it excellent for erosion control and water infiltration.
• Native pollinator habitat. Buffalo grass provides habitat for native insects and birds. It is a host plant for several skipper butterfly species.

Where Buffalo Grass Does Not Work

Be honest about the limitations. Buffalo grass is not right for every St. Charles County property:

• Heavy shade. Buffalo grass needs full sun — at least 8-10 hours of direct sunlight daily. It will not survive under trees or on north-facing slopes. For shade, use fine fescue.
• High traffic. Buffalo grass does not recover well from foot traffic. Children’s play areas, dog runs, and pathways will wear thin.
• Want year-round green. Buffalo grass goes dormant and turns tan from mid-October through mid-April. In Missouri, that is 6 months of brown lawn. If you want green grass in winter, plant cool-season grass instead or overseed with annual ryegrass in fall.
• Weed-free perfection. Buffalo grass grows in a looser, more open turf than tall fescue. Some weeds will appear. A perfect monoculture is not the goal of a native grass lawn.

The Ideal Buffalo Grass Property

Buffalo grass is best for St. Charles County homeowners who:

• Have a large, sunny lawn (front yard, backyard, or both)
• Want to reduce water bills and mowing time significantly
• Are comfortable with a natural-looking, non-traditional lawn
• Live in a neighborhood without strict HOA rules requiring manicured cool-season turf
• Have a septic drain field (Buffalo grass’ deep roots are less likely to clog than shallow-rooted cool-season grasses)

How to Establish Buffalo Grass in Missouri

Choosing the Right Cultivar

Not all Buffalo grass is the same. For home lawns in St. Charles County, choose a turf-type cultivar bred for lawn use:

Cultivar	Best For	Notes
Cody	Northern lawns	Best cold tolerance for St. Charles County
Bowie	General lawn use	Good turf density, moderate cold tolerance
Bison	Low-maintenance areas	Shorter growing season, stays smaller
Turffalo	Premium lawn look	Densest turf of all cultivars, best weed resistance
Legacy	Quick establishment	Improved germination rate from seed

Cody and Bowie are the most reliable choices for St. Charles County’s climate (USDA Zone 6a/6b). Turffalo is the best choice if you want a premium look and are willing to spend more on seed.

Seeding vs Sod vs Plugs

Method	Cost per 1,000 sq ft	Time to Full Coverage	Best Time
Seed (hulled)	$15-30	2-3 months	May–June
Plugs	$60-100	3-4 months	May–July
Sod	$200-400	Immediate	May–August

Seeding is the most practical method for most homeowners. Buffalo grass seed comes in two forms:

• Hulled seed (the outer husk removed): Germinates in 7-14 days. More expensive but faster establishment.
• Unhulled seed (seed in the natural husk): Germinates in 14-30 days. Cheaper but slower. The husk protects the seed but delays germination.

For St. Charles County, use hulled seed for lawn establishment. The extra cost is worth the faster, more uniform result.

Seeding Instructions

When to plant: Late May through early July is ideal. Soil temperatures should be 70°F or higher. Buffalo grass is a warm-season grass — it will not germinate in cool spring soil.

1. Prepare the seedbed. Remove existing vegetation. Till or rake the top 2-3 inches of soil. Level any uneven areas. Buffalo grass seed is small and needs fine, firm soil for good seed-to-soil contact.
2. Apply starter fertilizer if needed. Only if a soil test shows very low phosphorus. Otherwise, skip it.
3. Sow the seed. Broadcast at 2-3 lbs per 1,000 sq ft for hulled seed, or 4-6 lbs for unhulled seed. Sow half in one direction and half perpendicular.
4. Cover lightly. Rake to cover seeds with no more than 1/4 inch of soil — Buffalo grass seed needs light to germinate.
5. Roll the area. Use a lawn roller to press seeds into firm contact with the soil.
6. Water consistently. Keep the top inch of soil moist for the first 3 weeks. After germination, gradually reduce to deep, infrequent watering.

First-Year Care

The first year of Buffalo grass is the hardest. The grass grows slowly compared to tall fescue and weeds will try to take over. Key tips:

• Control weeds carefully. Do not use pre-emergent herbicides during seeding — they prevent Buffalo grass from germinating too. Spot-treat broadleaf weeds after the Buffalo grass has reached 3 inches tall.
• Mow at the right height. Do not mow Buffalo grass until it reaches 4 inches tall. Then mow to 2.5-3 inches. Never cut more than one-third of the leaf blade at once.
• Be patient. Buffalo grass is slow to establish in year one. By year two, the root system is deep enough to outcompete most weeds and the lawn fills in.

Buffalo Grass Care Calendar

Yearly Care Overview

Season	Mowing	Watering	Fertilizer
April–May (green-up)	None or very light trim	None — spring rain is enough	None
June–August (peak growth)	Every 2-3 weeks at 2-3 inches	0.5-1 inch per month if no rain	Optional: 0.5 lb N in June
September (transition)	Every 2-3 weeks, taper off	None — fall rain is enough	None
October–March (dormancy)	None — grass is dormant brown	None	None

Spring (April–May) — Green-Up

Buffalo grass is one of the last grasses to green up in spring. It waits until soil temperatures reach 60°F consistently — usually mid-to-late April in St. Charles County. Do not worry if the lawn looks dead while neighbors’ tall fescue is already bright green.

• Rake out dead debris gently with a leaf rake. Do not dethatch aggressively — Buffalo grass has stolons near the surface.
• No fertilizer. Spring rains and warming soil provide everything Buffalo grass needs.
• Overseed thin spots in late May when soil is warm enough.
• Apply pre-emergent in early April if you had crabgrass or foxtail problems last year. Use a product labeled safe for Buffalo grass.

Summer (June–August) — Peak Growth

This is when Buffalo grass shines. It thrives in heat that would send tall fescue into stress.

• Mow every 2-3 weeks at 2-3 inches. Leave clippings on the lawn — they return nutrients.
• Water deeply but rarely. Give 0.5-1 inch every 2-3 weeks if there is no rain. Overwatering encourages weeds and disease.
• Spot-treat weeds as needed. Buffalo grass is naturally weed-resistant once established, but broadleaf weeds and crabgrass can appear in the first year or two.
• Check for chinch bugs in July and August. Buffalo grass is generally resistant but can be damaged by severe infestations.

Fall (September–October) — Transition to Dormancy

Buffalo grass slows down as days shorten and temperatures drop.

• Taper mowing. Mow every 3-4 weeks in September, then stop when the grass goes tan.
• No fertilizer. Fall fertilization encourages winter weeds and does not benefit Buffalo grass.
• Do not overseed with cool-season grass unless you want a “green winter look.” Some homeowners overseed Buffalo grass with annual ryegrass in September for winter color. The annual ryegrass dies in late spring, and the Buffalo grass regrows through it. This works but adds a mowing requirement in fall and spring.

Winter (November–March) — Full Dormancy

Buffalo grass is completely dormant and tan from the first hard frost through late April.

• Do not mow. The dormant grass protects the crowns and stolons from winter cold.
• Do not walk on frozen dormant grass. Traffic on frozen stolons can damage the growing points.
• No maintenance needed. This is the payoff — 5 months of zero lawn work.

Common Buffalo Grass Problems

Weed Invasion During Establishment

The most common complaint: “I planted Buffalo grass and now I have more weeds than grass.” This is normal in the first year. Buffalo grass is slow to germinate and establish. Weeds that germinate quickly will fill bare soil first. Solutions:

• Mow at 3 inches. Keeping Buffalo grass at 2-3 inches encourages lateral spread and shades out many weeds.
• Spot-treat broadleaf weeds with a selective herbicide labeled for Buffalo grass.
• Wait for year two. By the second summer, Buffalo grass forms a dense sod that naturally suppresses most weeds.

Green Winter Color (From Homeowners Who Want It)

If you want green grass in winter, you have two options:

1. Plant cool-season grass instead. Buffalo grass is brown for 5-6 months. Accept this as a feature of native grass.
2. Overseed with annual ryegrass in mid-September. The ryegrass germinates quickly, stays green through winter, and dies naturally in late May when Buffalo grass takes over. This works but requires fall and spring mowing.

Chinch Bugs

Chinch bugs occasionally attack Buffalo grass in hot, dry summers. Signs: yellow or brown patches that do not respond to watering. Treatment: apply a labeled insecticide (bifenthrin or carbaryl) at the first sign of damage, or use beneficial nematodes for a chemical-free option.

HOA Restrictions

Before planting a Buffalo grass lawn, check your HOA covenants. Some St. Charles County homeowners associations require traditional cool-season turf and do not allow warm-season grasses that go dormant. If your HOA has strict landscaping rules, Buffalo grass may not be an option unless you are willing to request a variance.

FAQ

Does Buffalo grass stay green in summer?

Yes, Buffalo grass is at its greenest from June through September. It stays green through the hottest, driest parts of Missouri summer without supplemental watering, outperforming every cool-season grass during July and August.

How long does it take for Buffalo grass to establish?

From seed, expect visible germination in 7-21 days. Full lawn coverage takes 2-3 months in ideal conditions. Year two is when the lawn really fills in and starts looking its best.

Can I mix Buffalo grass with tall fescue?

Do not mix them. Buffalo grass grows best alone because its warm-season growth cycle conflicts with cool-season grasses. A mixed lawn will look patchy — green in spring and fall (tall fescue dominant), green in summer (Buffalo grass dominant), and brown in the transitions when one is going dormant and the other is greening up.

Is Buffalo grass expensive?

Seed is comparable to other grass types ($15-30 per 1,000 sq ft). The long-term savings are significant — lower water bills, no fertilizer costs, and far less gasoline for mowing. Over 5 years, a Buffalo grass lawn costs roughly 60% less to maintain than tall fescue.

Is Buffalo grass good for erosion control on slopes?

Excellent. The deep root system (4-6 feet) binds soil better than any shallow-rooted cool-season grass. It is commonly used for erosion control along roadsides and on construction sites in the Great Plains.

Will Buffalo grass take over my flower beds?

Buffalo grass spreads by stolons (above-ground runners) but is less aggressive than Bermuda grass. It can creep into beds if not edged regularly. A 4-inch deep edging barrier or annual edging with a string trimmer controls it easily.
