Summer Grass Seed

Summer can be a great time to seed the right type of grass. Whether you're installing a new Bermuda lawn or maintaining cool-season turf in high-heat conditions, choosing the right seed and following proper care practices are critical for success. Our premium, weed-free grass seed blends are designed to thrive in summer’s demanding conditions.

Best Grass Types to Seed in Summer

Bermudagrass is the best option for summer seeding in warm-season areas. It loves heat, germinates quickly in warm soil, and thrives in full sun. With proper watering and soil prep, you can establish a strong Bermuda lawn during the summer months.

Can You Seed Cool-Season Grass in Summer?

Yes—but with caution. Tall fescue and Kentucky bluegrass can technically be seeded in summer, but germination is more challenging due to high temperatures and rapid moisture loss. If you choose to seed cool-season grass in summer:

  • Water multiple times daily to keep the soil consistently moist
  • Topdress with peat moss or wheat straw to protect seed and hold in moisture
  • Monitor daily—hot, dry conditions can kill seedlings quickly

Fall remains the best time for cool-season grass seeding, but summer seeding can work with strict care and attention.

How Much Seed Should You Apply?

  • Overseeding: 4–5 lbs per 1,000 sq ft
  • New Lawn Installation: 8–10 lbs per 1,000 sq ft

Soil Prep for Summer Seeding

For successful summer seeding, always start with proper prep:

  1. Loosen the topsoil to improve seed-to-soil contact
  2. Rake out debris and dead grass
  3. Topdress with peat moss or wheat straw after seeding to retain moisture

Watering Grass Seed in Summer

High temperatures can dry out seed beds quickly. To ensure germination:

  • Water 2–3 times per day with light applications until germination
  • Keep the top ¼ inch of soil consistently moist
  • Reduce frequency and water deeper once seedlings are 2–3 inches tall

Frequently Asked Questions

Can you plant grass seed in summer?

Yes. Bermudagrass is ideal for summer seeding in hot climates. You can also plant cool-season grasses like tall fescue, but they require daily watering and close monitoring due to heat stress.

What grass grows best when seeded in summer?

Bermudagrass is the top choice for summer seeding. It thrives in hot weather, establishes quickly, and performs well in sunny areas.

Can I seed tall fescue in summer?

You can, but be prepared to water multiple times per day. Without consistent moisture and topdressing, the seed will dry out and fail to germinate in high heat.

How much seed should I apply in summer?

For overseeding, use 4–5 lbs per 1,000 sq ft. For new lawns, apply 8–10 lbs per 1,000 sq ft. Always ensure good seed-to-soil contact and moisture retention.

Do I need to topdress summer seed with straw or peat moss?

Yes. Topdressing is essential in summer to keep the seed bed cool and moist. It greatly increases germination success, especially for cool-season seed.
