Warm-season grasses thrive in southern heat. When cool-season grasses are turning brown and going dormant, warm-season grasses are just hitting their stride. If you live where summers are long and hot, you need warm-season grass seed.
I have helped friends and family seed warm-season lawns from Texas to Florida. The right seed makes all the difference. Here is what works.
What Are Warm-Season Grasses?
Warm-season grasses grow best when temperatures are between 80 and 95 degrees. They love heat and humidity. They go dormant and turn brown in winter when temperatures drop below 50 degrees.
The main warm-season grasses are Bermuda, zoysia, St. Augustine, centipede, and bahia. Some grow from seed. Some only grow from sod or plugs. I will focus on the ones you can actually seed.
My Top 5 Warm-Season Grass Seeds
1. Scotts Turf Builder Bermuda Grass Seed (Best Overall)
Bermuda grass is the king of warm-season lawns. It handles heat, drought, and heavy foot traffic. Scotts Bermuda seed is coated for moisture retention. Germination takes 7 to 14 days in warm soil.
Bermuda spreads aggressively through runners and rhizomes. It fills bare spots on its own. The downside is that it invades flower beds. You need good edging to keep it contained.
One 5-pound bag covers about 5,000 square feet for overseeding.
2. Pennington Bermuda Grass Seed (Best for Sun)
Pennington Bermuda seed grows a dense fine-textured lawn. It is a improved variety that stays greener longer into fall than common Bermuda. The seed quality is excellent with high germination rates.
I have seen Pennington Bermuda lawns that look almost like golf course fairways. It needs full sun. Eight hours minimum. Any shade and it thins out.
3. Scotts Turf Builder Zoysia Grass Seed (Best for Shade Tolerance)
Zoysia is the only warm-season grass that tolerates moderate shade. If you have trees but still want a warm-season lawn, zoysia is your answer. It also handles cold better than Bermuda.
The trade-off is speed. Zoysia germinates in 14 to 21 days. It spreads slower than Bermuda. You need patience. But once established, zoysia forms a thick carpet that chokes out weeds.
Zoysia seed has been available only recently. Scotts is one of the few companies that sells it.
4. Scotts Turf Builder Centipede Grass Seed (Best Low-Maintenance)
Centipede grass is called the lazy man’s grass for a reason. It grows slowly. It needs less mowing. It needs less fertilizer than any other warm-season grass. If you want a decent lawn with minimal effort, this is it.
Centipede does not handle heavy foot traffic. It is for show lawns, not play lawns. It also needs acidic soil with pH between 5.0 and 6.0. Test your soil before planting centipede.
5. Hancock Seed Co. Bahia Grass Seed (Best for Poor Soil)
Bahia grass is tough. It grows in sandy soil, clay soil, and everything in between. It handles drought better than Bermuda. It needs even less fertilizer than centipede.
The downside is that bahia is coarse and light green. It is not a pretty lawn grass. It is a functional lawn grass. Good for large rural properties where looks matter less than survival.
Warm-Season Grass Seed Comparison
| Grass | Germination | Sun Needs | Traffic |
|---|---|---|---|
| Bermuda | 7-14 days | Full sun | Excellent |
| Zoysia | 14-21 days | Sun to partial shade | Good |
| Centipede | 14-21 days | Full sun | Fair |
| Bahia | 10-14 days | Full sun | Good |
When to Plant Warm-Season Grass Seed
Plant warm-season grass seed in late spring to early summer. Soil temperature must be at least 65 degrees. For most southern states, this means May through July.
Do not plant warm-season grass seed in fall. The seedlings will not have time to establish before winter dormancy. They will die over winter and you will have bare dirt in spring.
Frequently Asked Questions
What is the easiest warm-season grass to grow from seed?
Bermuda grass is the easiest warm-season grass to grow from seed. It germinates fast, spreads quickly, and is forgiving of less-than-perfect soil. Zoysia and centipede are harder to establish from seed.
Can I plant warm-season grass in the fall?
No. Warm-season grass seed needs warm soil and warm air to germinate. Fall temperatures are too cool. The seedlings die over winter. Plant in late spring or early summer only.
Does warm-season grass stay green in winter?
No. Warm-season grasses go dormant and turn brown when temperatures drop below 50 degrees. This is normal. They green up again in spring when temperatures warm up. Some people overseed with annual ryegrass in fall for winter green color.
