The six best grass types for Louisiana’s hot, humid climate are Bahiagrass, Bermudagrass, carpetgrass, centipedegrass, St. Augustinegrass, and Zoysiagrass.
Any of these grasses enable you to have an attractive lawn, provided you also have a good maintenance program. But there are other factors to consider when choosing a grass because they each have different needs and preferences. We explain all those factors in this article.
6 Warm-Season Grasses for Louisiana
Turfgrass falls into two categories: cool-season and warm-season grasses. Here, the summers are long and hot and the winters are short and warm. In Cajun Country, warm-season cultivars dominate the landscape, thriving in our warm and humid conditions. Popular varieties include:
1. Bahiagrass
When it comes to durability, adaptability, and low-maintenance requirements, bahiagrass emerges as one of the top choices for Louisiana lawns. With its natural tolerance to high temperatures, humidity, and heavy rainfall, this warm-season grass is particularly well-suited for lawns across the state, including the Southern and Coastal regions.
Bahiagrass is also drought-tolerant, ensuring its resilience in the face of Louisiana’s unpredictable weather. This turfgrass doesn’t form a thick lawn, but its medium green color and coarse texture make it appear more dense. It also grows fast and stands up to pests and diseases well, though you should avoid overwatering it.
Classification: Warm-season grass
Spreads by: Rhizomes
Shade tolerance: Low — it needs direct sun exposure
Drought resistance: High
Foot traffic tolerance: Low
Maintenance needs: Moderate to high — plan to mow often during the growing season
Mowing height: 3-4 inches
Potential for disease: Low
Potential for pests: Moderate
Soil pH: 5.5-6.5
Soil type: Tolerates most soils, does well in sandy loam
Other notes: Commonly grown in the Gulf Coast and Southeast, bahiagrass does best in acidic soils but doesn’t tolerate saltwater well.

2. Bermudagrass
Also known as Bahama grass or dog’s tooth grass, bermudagrass is well-suited for the Southern regions of Louisiana, where the climate leans towards subtropical. Its drought tolerance enables it to withstand dry spells and the scorching Louisiana summers.
Bermudagrass is the most common warm-season turfgrass in the South. It is a tough grass that can withstand heavy foot traffic and recover quickly thanks to its fast growth rate. However, it can spread aggressively into flower beds and other lawns if not maintained. It also requires frequent fertilization and watering during the summer growing season.
Classification: Warm-season grass
Spreads by: Stolons and rhizomes
Shade tolerance: Poor — needs full sun
Drought resistance: High
Foot traffic tolerance: High
Maintenance needs: Needs frequent mowing due to fast growth rate; develops thatch easily; needs regular fertilization
Mowing height: 1-2 inches
Potential for disease: Moderate resistance — although diseases like brown patch and dollar spot are common
Potential for pests: Low resistance
Soil pH: 6-6.5
Soil type: Thrives in most soil types but prefers loam soil
Other notes: Bermudagrass can be a nuisance due to its ability to spread aggressively. It is sometimes considered invasive. You’ll often find it has tunneled underground into flower beds and spread into neighboring lawns.

– Scotts Turf Builder Bermudagrass (10-lb. bag)
– Hancock Seed Co. Bermudagrass (50-lb. bag)
3. Carpetgrass
Carpetgrass, also known as Louisianagrass, is well-suited for the Coastal and Southern regions, where the weather is warm and humid. Additionally, its ability to tolerate acidic soils makes it ideal for the Bayou State, where the pH levels may be less favorable for other grass types.
As a low-maintenance option, carpetgrass has found a special place in the hearts of many Louisiana homeowners. While it’s not particularly drought-resistant, it only needs one inch of water per week to survive and keep its healthy appearance. It has a coarse texture and creates a dense, light-to-medium green lawn.
Classification: Warm-season grass
Spreads by: Stolons
Shade tolerance: Moderate, but not as high as St. Augustinegrass
Drought resistance: Moderate, but won’t survive in dry conditions (shallow roots)
Foot traffic tolerance: Low to moderate
Maintenance needs: Mow weekly to control tall seed heads
Mowing height: 1-2 inches
Potential for disease: Low resistance — large patch is common
Potential for pests: Low resistance
Soil pH: 5-6
Soil type: Infertile, moist but not waterlogged, acidic, sandy soil
Other notes: Usually established by seed, carpetgrass flourishes in warm and humid conditions along the Gulf Coast. It’s not salt-tolerant and does not thrive in arid climates.
Grass Seed Option:
– Carpetgrass seeds (coated) (2 lbs.)
4. Centipedegrass
Though slow-growing, centipedegrass is considered one of the best grass types for Southern Louisiana due to its ability to thrive in heat and humidity. Commonly used in lawns, parks, and golf courses across the state, this medium-textured grass has bright green leaves and produces dense lawns.
Centipedegrass handles moderate shade making it suitable for areas where trees or structures cast shadows. This warm-season grass is also well-adapted to the state’s frequent rainfall. On the downside, centipedegrass isn’t exceptionally drought-tolerant and requires sandy soil and lime amendments for steady growth.
Classification: Warm-season grass
Spreads by: Stolons
Shade tolerance: Moderate — requires at least six hours of full sun per day
Drought resistance: Low to moderate
Foot traffic tolerance: Low
Maintenance needs: Low mowing frequency
Mowing height: 1.5-2 inches
Potential for disease: Good resistance to diseases
Potential for pests: Low resistance
Soil pH: 5-6
Soil type: Acidic, infertile, at least moderately good drainage (very dense, clay soils produce poor results)
Other notes: While it’s not salt-tolerant, this grass type has a pretty greenish-yellow color (like a green apple) during the growing season
Grass Seed Options:
– Gulf Kist Coated Centipedegrass Seeds (1 lb.)
– Scotts EZ Seed Patch and Repair Centipedegrass (3.75 lbs.)
– TifBlair Centipedegrass (5-lb. bag)
5. St. Augustinegrass
Louisiana’s vast geographical diversity, from the humid subtropical climate of the Southern regions to the more temperate conditions in the north, demands a versatile grass species that can withstand the state’s ever-changing weather. St. Augustinegrass emerges as the clear frontrunner, adapting to a wide range of climates and soil types.
Also known as buffalo turf in certain parts of the world, St. Augustinegrass has an impressive tolerance to humidity and can thrive in the hottest parts of Louisiana. It is also salt-tolerant, growing well in the Gulf Coastal Plain and river valleys. This resilient, dark-green grass flourishes in Louisiana with a fast growth rate.
Classification: Warm-season grass
Spreads by: Stolons
Shade tolerance: Moderate shade tolerance, among the highest of any warm-season grass; some cultivars are more shade tolerant than others
Drought resistance: Moderate
Foot traffic tolerance: Moderate
Maintenance needs: Moderate to high mowing frequency
Mowing height: 2.5-4 inches (mow dwarf varieties from 2.5-3 inches; standard cultivars from 3-4 inches; mow tall in shade)
Potential for disease: Low to moderate — gray leaf spot and large patch are common
Potential for pests: Low resistance
Soil pH: 6-7.5
Soil type: Tolerates many soil types but prefers moderately fertile and moist (not waterlogged) soils; doesn’t tolerate soil compaction
Other notes: Native to coastal areas, St. Augustinegrass prefers moist soils and mild winters but can thrive in inland areas, provided growing conditions are met. It has good salt tolerance but will go dormant during the winter, except in the Southern regions.
