How To Get Rid Of Buffalo Grass: Permanent Removal And Control Methods
Buffalo grass (Buchloe dactyloides) is a notoriously resilient, drought-tolerant native turfgrass that aggressively invades flower beds, vegetable gardens, and non-native lawns via persistent stolons and deep fibrous roots. Successfully eradicating it requires a systematic approach combining mechanical extraction, non-selective chemical intervention, and aggressive post-removal cultural management to prevent regeneration from dormant rhizomes.
Pre-Operation & Planning Checklist
Eliminating buffalo grass from a landscape requires matching the correct eradication methodology to the scale of the infestation, the surrounding desirable vegetation, and the site's environmental conditions. Because buffalo grass stores significant energy reserves in its extensive root system, haphazard pulling or superficial tilling often triggers a more aggressive rebound.
- Essential Tools and Materials: Heavy-duty flat-blade shovel, border edger, garden fork, utility-grade landscape fabric, 3-mil black plastic sheeting for solarization, heavy-duty weed barrier pins, glyphosate-based non-selective herbicide (41% active ingredient), pump-up sprayer, and appropriate personal protective equipment including nitrile gloves and eye protection.
- Prerequisite Standards: Identify whether you are managing a spot invasion in a traditional cool-season lawn (like Kentucky bluegrass or tall fescue) or clearing an entire area for a complete landscape redesign. Chemical treatments must be executed during active growth phases when daytime temperatures consistently exceed 65 degrees Fahrenheit.
- Estimated Budget and Duration: DIY mechanical and chemical eradication projects generally cost between 30 and 150 dollars for supplies, depending on the square footage. Complete solarization protocols require 6 to 8 weeks of continuous summer heat, while chemical and physical removal can be completed across a 14-day execution window followed by seasonal monitoring.
Step-by-Step Eradication Workflow
Step 1: Mapping the Infestation and Establishing Physical Boundaries
Before applying any chemical or mechanical treatments, accurately define the perimeter of the buffalo grass patch to prevent collateral damage to desirable plants or turfgrass. Use a mechanical half-moon edger to cut a vertical trench 4 to 6 inches deep around the entire perimeter of the buffalo grass infestation.
Warning: Never use rotary tillers to break up an unmitigated buffalo grass patch. Tilling chops the stolons and rhizomes into hundreds of viable fragments, multiplying the infestation exponentially across your landscape.
Step 2: Applying Systematic Non-Selective Herbicides
For large infestations or total lawn takeovers, chemical eradication using a systemic, non-selective herbicide containing glyphosate is the most efficient pathway. Mix the herbicide according to manufacturer specifications—typically 2 to 2.5 ounces per gallon of water—and add a non-ionic surfactant to improve leaf cuticle penetration.
- Ensure the buffalo grass is actively growing and has not been mowed for at least 7 to 10 days to maximize leaf surface area for absorption.
- Calibrate your pump-up sprayer to deliver a uniform, low-pressure fan spray, completely coating the green foliage without excessive runoff.
- Allow 7 to 14 days for the systemic chemical to translocate down to the deepest root tips, resulting in complete yellowing and desiccation of the plant tissue.
Pro-Tip: If stubborn green patches remain after 14 days, perform a localized secondary spot-treatment rather than blanketing the entire area again to minimize chemical loading in your soil matrix.
Step 3: Mechanical Excavation and Root Extraction
Once the top growth is dead or if you are managing a small garden bed where chemicals are prohibited, manual excavation is necessary to remove the dense mat of roots and crowns. Use a sharp garden fork or flat-blade shovel to slice underneath the turf layer at a depth of 4 to 6 inches.
- Pry upward gently while pulling backward on the dead or dying buffalo grass mat, rolling it up like carpet.
- Sift through the underlying loose soil with a hand cultivator to extract any remaining white, fleshy stolon nodes or severed root segments.
- Bag all excavated material immediately in heavy-duty yard waste bags; do not add live buffalo grass stolons to backyard compost bins, as they can easily survive and re-root.
Step 4: Soil Solarization for Chemical-Free Eradication
If you prefer an organic, chemical-free approach for large beds, solarization harnesses solar radiation to thermally kill both the buffalo grass plants and their underlying root structures.
- Clear the target zone of all rocks, sticks, and tall debris, then rake the soil surface until it is smooth and level.
- Water the soil thoroughly to a depth of at least 6 inches, as wet soil conducts heat more efficiently and increases thermal death rates for plant tissues.
- Cover the dampened area tightly with 1 to 2 mil clear polyethylene plastic sheeting, burying all edges securely in trenches filled with soil to trap ambient heat and moisture. Leave the plastic undisturbed for 6 to 8 weeks during peak summer conditions.
Comparative Analysis of Buffalo Grass Removal Methods
| Removal Method | Labor Intensity | Time to Completion | Environmental Impact | Reinfestation Risk | Best Use Case |
|---|---|---|---|---|---|
| Systemic Herbicide | Low to Moderate | 14 – 21 Days | Moderate (Chemical use) | Low | Large areas, turf conversions |
| Manual Excavation | High | 1 – 3 Days | Zero | Medium | Small garden beds, spot invasions |
| Soil Solarization | Low | 6 – 8 Weeks | Zero | Low | Chemical-free large zone clearing |
| Sheet Mulching | Moderate | 3 – 6 Months | Zero | Low | Permaculture and garden conversions |
Common Site Failures and Field Fixes
- Root Regeneration from Surviving Nodes:
- Root Cause: Incomplete manual extraction left behind viable nodes, or herbicide application missed deeply buried crown tissues.
- Actionable Fix: Monitor the treated area weekly during the following growing season and immediately spot-treat emerging green shoots with a glyphosate weed wand or manual dig-out before they re-establish energy reserves.
- Drift Damage to Neighboring Ornamental Plants:
- Root Cause: Spraying systemic herbicide on a windy day or failing to use physical shields around desirable landscape plants.
- Actionable Fix: Prune away severely affected branches on damaged ornamentals, flush surrounding soil with water to dilute minor chemical overspray, and apply balanced liquid kelp fertilizer to stimulate stress recovery.
- Immediate Weed Colonization of Bare Soil:
- Root Cause: Eradicating the buffalo grass left open, unmulched soil exposed to airborne weed seeds and dormant annual weed banks.
- Actionable Fix: Apply a 3-inch layer of organic shredded bark mulch immediately after excavation or instantly overseed the area with a dense, desirable turfgrass variety to outcompete secondary invaders.
Frequently Asked Questions
Will mowing buffalo grass short kill it?
No. Buffalo grass is remarkably tolerant of low mowing heights and frequent clipping. Mowing short will simply force the grass to adapt by growing its horizontal stolons closer to the soil surface, making manual extraction even more difficult.
Can buffalo grass choke out other grasses?
Yes. In regions with low annual rainfall and alkaline soils, buffalo grass forms a dense, tight sod matrix that aggressively outcompetes traditional cool-season lawns for moisture, sunlight, and macro-nutrients.
How do I stop buffalo grass from creeping into my flower beds?
Install heavy-duty physical root barriers made of corrugated plastic or aluminum edging that extend at least 6 inches vertically into the soil. Maintain a 3-inch wide mulch buffer strip along the barrier edge to allow for easy visual inspection and hand clipping of any jumping stolons.
Is it safe to replant immediately after using glyphosate?
Glyphosate deactivates upon contact with soil particles and leaves no residual soil activity. You can safely sow new grass seed, lay fresh sod, or plant ornamentals as soon as 3 to 7 days after the final herbicide application has visibly killed the target vegetation.
