Does Buffalo Grass Grow Back?
Yes, buffalo grass almost always grows back if the roots are alive and conditions improve. This warm-season turf naturally enters dormancy during cold or drought, turning brown and appearing dead, but it reliably greens up again when temperatures rise and moisture returns. However, recovery is not automatic if the grass has suffered from disease, heavy thatch, or complete root death.
Buffalo grass is one of the most drought-tolerant lawn options available, making it popular in dry regions from the Great Plains to the Southwest. It’s also low-maintenance once established, but you still need to understand its growth cycle to keep it healthy. This article explains when and how buffalo grass regrows, what can prevent it, and how to help it bounce back.
What Is Buffalo Grass and Why Does It Go Dormant?
Buffalo grass (Bouteloua dactyloides) is a warm-season perennial grass native to North America. It’s adapted to hot summers and cold winters, and it uses dormancy as a survival strategy. When soil temperatures drop below 50°F or moisture becomes scarce, the grass stops growing and turns tan or brown. This is not death—it’s a protective state where the plant conserves energy in its roots and stolons (above-ground runners).
During dormancy, the grass blades dry out and the plant’s metabolic activity slows way down. The crown and root system remain alive, waiting for warmer weather or rainfall. If you see your buffalo grass turn brown in late fall or during a summer drought, do not panic. It will grow back once the temperature or moisture conditions become favorable again.
How Does Buffalo Grass Come Back After Dormancy?
Recovery from dormancy starts when soil temperatures stay consistently above 60°F and moisture is available. The process is gradual:
- Roots and stolons sense the warmer soil and begin to activate stored carbohydrates.
- New shoots emerge from the crown near the surface.
- Stolons start to spread and fill in bare patches.
- Full green color returns after a few weeks of active growth, provided there is enough sunlight.
Buffalo grass typically breaks dormancy in late spring, around the same time that air temperatures reach the 70s. If you have a cool, wet spring, regrowth may be slower. If the spring is warm and dry, you might need to water once or twice to trigger growth. Avoid fertilizing until the grass is fully green and growing, or you may burn the emerging shoots.
Does Buffalo Grass Grow Back After Drought or Dry Spells?
Yes, buffalo grass is extremely drought-tolerant and can survive long dry periods by entering summer dormancy. It will turn brown and stop growing, but the root system stays alive. Once rain returns or you provide irrigation, the grass will regrow from the crowns and stolons.
However, prolonged drought longer than 4 to 6 weeks without any moisture can cause root death, especially in sandy soils. To protect your lawn during a severe drought, give it a deep soak every 3 to 4 weeks. Just an inch of water can keep the root system hydrated enough to regrow later.
Common mistake: Many homeowners assume the grass is dead and reseed or sod over it during a dry spell. Wait until after the dry period ends to assess recovery. Raking or aerating a dormant lawn can also damage the stolons and delay regrowth.
Can Buffalo Grass Recover From Winter Damage or Frost?
Buffalo grass is winter-hardy in USDA zones 4 through 9, but it can suffer winter damage if the crown is exposed to extremely low temperatures without snow cover or if the grass is mowed too short before dormancy.
Winterkill happens when temperatures drop below -20°F and the ground freezes deep enough to kill the roots. In milder winters, the grass should regrow from the stolons in spring. If you notice large bare patches after the last frost, check the roots: dig up a small patch and look for white, firm roots. Brown, mushy roots mean that part of the lawn has died and needs reseeding.
To reduce winter damage:
- Mow buffalo grass to about 2 inches before the first freeze.
- Leave the clippings on the lawn as mulch.
- Avoid heavy foot traffic on frozen grass.
Will Buffalo Grass Grow Back After Overwatering or Disease?
Overwatering is one of the few things that can kill buffalo grass. It thrives on little water, and wet soil promotes root rot and fungal diseases. If you water too often, the grass may turn yellow or brown and fail to regrow even when conditions improve.
If you suspect overwatering damage:
- Stop watering immediately.
- Allow the soil to dry out completely.
- Check for take-all patch or dollar spot—common fungal diseases in buffalo grass that cause patches of dead grass that do not regrow.
Diseased grass does not grow back on its own. You must treat the underlying infection with a fungicide and then reseed bare spots. To prevent disease, water deeply but infrequently (once every 7–10 days in summer) and only in the early morning.
How to Help Buffalo Grass Grow Back After Weed Infestation
Weeds compete with buffalo grass for light, water, and nutrients. A heavy weed infestation can weaken the grass so much that it can’t regrow properly. The most common culprits are crabgrass, dallisgrass, and bindweed.
To help your grass recover after weeds:
- Manually pull large weeds or spot-treat with a post-emergent herbicide labeled for buffalo grass. Do not use broadleaf herbicides on buffalo grass during its active growth phase; use a selective product like quinclorac for crabgrass.
- Mow at the correct height (1.5 to 2 inches) to shade out weed seedlings.
- Fertilize lightly with a slow-release nitrogen fertilizer to encourage buffalo grass to fill in gaps. A good choice is Milorganite slow-release nitrogen fertilizer.
- Overseed bare areas in late spring with fresh buffalo grass seed if stolons have not spread into the spots within a month.
Weed control is not a one-time fix. Keep the grass healthy, and it will naturally crowd out most weeds over time.
How Long Does It Take for Buffalo Grass to Regrow?
The timeline depends on the cause of the dieback and the growing conditions.
| Situation | Time to full recovery |
|---|---|
| Normal spring green-up from dormancy | 2 to 4 weeks after consistent 60°F+ soil temps |
| Recovery after light drought (2–3 weeks dry) | 1 to 2 weeks after rainfall or irrigation |
| Recovery after heavy drought (4–6 weeks dry) | 3 to 6 weeks |
| Regrowth after overseeding bare spots | 3 to 4 weeks for germination, 6–8 weeks for full cover |
| Recovery after winterkill (partial damage) | 4 to 8 weeks if stolons remain; may need reseeding if crown is dead |
Buffalo grass spreads by stolons, so it does not fill in as fast as sod-type grasses. Patience is key. Do not expect a lush green carpet overnight.
Common Mistakes That Prevent Buffalo Grass From Growing Back
Avoid these errors if you want reliable regrowth:
- Scalping the lawn in spring. Mowing too low removes the growing point (crown) and can kill the grass. Keep the height at 1.5 to 2 inches.
- Fertilizing too early. Applying nitrogen when the grass is still dormant feeds weeds and burns the roots. Wait until the grass is at least 50% green.
- Overwatering during dormancy. This suffocates the roots and invites fungal disease.
- Heavy thatch buildup. Over ½ inch of thatch blocks water and air from reaching the roots. Dethatch in early spring every 2–3 years if needed.
- Using a pre-emergent herbicide in spring too early. Pre-emergents can prevent stolon rooting and seedling growth. Apply only after the grass is fully green and actively growing.
- Ignoring soil compaction. Buffalo grass roots need loose soil to spread. Aerate in late spring if the soil is hard or clay-rich.
Best Practices for Encouraging Buffalo Grass Regrowth Year After Year
To ensure your buffalo grass comes back strong every season, follow this simple care checklist:
- Test your soil pH every 2 to 3 years. Buffalo grass prefers a pH between 6.0 and 7.5. Use a home soil test kit to check.
- Water deeply but rarely. Once every 7–10 days during active growth, giving about 1 inch of water per session.
- Mow at 1.5 to 2 inches during summer. Do not remove more than one-third of the blade height at a time.
- Fertilize lightly in late spring and again in midsummer. Use a slow-release fertilizer with a 3-1-2 or 4-1-2 ratio. Too much nitrogen causes thatch and reduces drought tolerance.
- Control thatch if it exceeds ½ inch. Rake or use a dethatcher in early spring.
- Overseed bare spots in late spring or early summer when soil temperatures are above 65°F. Choose a variety like Buffalo grass seed (Bouteloua dactyloides) suited to your area.
- Avoid herbicides during the first month of spring green-up. Hand-pull weeds instead.
- Leave clippings on the lawn. They return nutrients and help retain moisture.
Does Buffalo Grass Grow Back? Yes, With the Right Care
Buffalo grass is built to survive tough conditions, and it will grow back from dormancy, drought, frost, and most minor damage as long as the roots are alive. The most important factors are patience and proper timing—do not water too much, do not fertilize too early, and do not assume brown grass is dead.
If you see bare patches that do not green up after 6 weeks of favorable weather, check the roots. If they are white and firm, the grass is just slow and will fill in eventually. If they are brown and brittle, reseed those spots in late spring. With a little attention to its natural cycle, your buffalo grass lawn will return year after year, reliable and low-maintenance.
