The best grass seeds to plant in summer are typically warm-season grasses known for their ability to thrive in high temperatures and bright sun.
When summer heat is at its peak, certain grass types excel. Unlike cool-season grasses that struggle or go dormant in the heat, warm-season grasses actively grow during the summer months. This makes summer an ideal time for seeding these specific varieties in areas where they are well-suited.
Top Warm-Season Grasses for Summer Planting
Based on their heat tolerance, several grass seed types are excellent choices for planting during the summer.
Bermudagrass
Bermudagrass is renowned for its exceptional heat tolerance. According to the reference, this grass is extremely heat tolerant, performing optimally in daytime temperatures ranging from 95 to 100 degrees Fahrenheit. It establishes quickly and forms a dense, durable turf that can withstand heavy use and high temperatures. For example, Pennington Bermudagrass Grass Seed is noted to yield dense, resilient, heat-tolerant lawns.
Other Heat-Tolerant Options
Beyond Bermudagrass, several other warm-season grasses tolerate high heat very well and are suitable for summer planting:
- Zoysia Grass: Known for its density and wear resistance, Zoysia grass forms a lush carpet-like lawn. While it can be slower to establish from seed than Bermudagrass, it is very heat and drought tolerant once mature.
- Centipede Grass: Often called the "lazy man's grass," Centipede grass requires less maintenance than some other types. It is a slow-growing, low-density grass that is very heat tolerant, though less cold tolerant than Bermudagrass or Zoysia. It prefers acidic soil.
- Bahiagrass: Particularly well-suited for sandy, infertile soils, Bahiagrass is known for its deep root system, which contributes to its excellent heat and drought tolerance. It is commonly used in pastures but can also be a durable, low-input lawn grass in warm climates.
Key Characteristics of Summer Grass Seeds
Here's a quick look at the heat tolerance of these summer-friendly grasses:
| Grass Type | Heat Tolerance | Notes on Growth/Use |
|---|---|---|
| Bermudagrass | Extremely High (Optimal 95-100°F) | Fast-growing, dense, resilient, handles traffic |
| Zoysia Grass | High | Dense, wear-resistant, slower to establish from seed |
| Centipede Grass | High | Low maintenance, slow-growing, prefers acidic soil |
| Bahiagrass | High | Drought tolerant, good for poor soil, deep roots |
Practical Summer Planting Tips
- Timing: Within the summer, planting earlier in the season (early to mid-summer) often provides the best opportunity for seeds to establish a strong root system before cooler weather arrives.
- Soil Preparation: Proper soil preparation is crucial. Clear the area of weeds, loosen the soil, and amend it with compost if necessary to improve drainage and fertility.
- Watering: Consistent watering is vital, especially in summer heat. Keep the top inch or two of soil consistently moist (but not waterlogged) until the seeds germinate and the seedlings are established. This may require frequent, light watering.
Choosing the right grass seed for summer planting depends on your specific climate within the warm-season zone, soil type, and desired lawn characteristics. However, Bermudagrass, Zoysia grass, Centipede grass, and Bahiagrass are proven performers in high heat.
