The best grass seed for overseeding a lawn will depend on the existing type of grass, the prevailing climate, and the soil type. After a few years, even the best-kept lawns can start to look sparse and worn out due to drought, under-watering, overwatering, or even growing a grass variety that’s not well suited to the region.
Overseeding a lawn with a superior variety of grass seed at least once every three years will keep the yard looking its best while helping it resist drought and disease. Ahead, learn what to look for when selecting a seed type, and find out why the following varieties were chosen as the best grass seed blends for overseeding lawns in different regions.

What to Consider When Choosing the Best Grass Seed for Overseeding
For the best results, choose a grass seed type that will grow well in your yard. The amount of sunlight the lawn receives, the general climate, and the kind of grass desired are all up for consideration. Additionally, the size of the yard and the seed’s coverage rate will play a role in how much seed you’ll need to overseed the lawn.
Types of Grass Seed
Not all types of grass seed grow well in all areas—some varieties are better suited to cold climates, while others thrive only in subtropical environments. When choosing grass seed for overseeding, select a type based on what grows best in your area. The best grass seed is one that will thrive in the specific region where it’s planted.
For example, grass seed that grows well in the Pacific Northwest may not grow in southern climates. In general, more cool-season grasses are grown from seed than are warm-season grasses. Several warm-season grasses, such as St. Augustine, are propagated by plugs rather than seeds, so overseeding is more common in regions with cool winters.
- Fescue: Among the fastest-growing grasses, fescue features several types with various textures. It’s prized for its drought resistance, will withstand moderate traffic, and grows in both sunny and shady spots.
- Kentucky bluegrass: Dense and durable, Kentucky bluegrass is a self-spreading, disease-resistant turf option that will tolerate cold temperatures. It’s not as drought resistant as fescue but provides a lush lawn that tolerates high traffic. The best Kentucky bluegrass seed often comes with a coating that absorbs moisture to help keep the seeds damp until they germinate.
- Perennial ryegrass: Useful for overseeding moderately cool- or warm-season grasses, perennial ryegrass requires a lot of water and doesn’t grow well in frigid climates.
- Buffalograss: Prized for its low maintenance, buffalograss thrives in the Midwest and Great Plains. It’s slow to green up in the spring and goes dormant early in the fall, however.
- Bermuda: Strictly a warm-weather grass, Bermuda produces a lush lawn in sunny yards and is drought tolerant. It doesn’t like cold weather and it doesn’t tolerate deep shade.
Climate and Sun Exposure
Researchers and seed manufacturers are busy hybridizing grass seed types to thrive in specific climates, such as the warm Southeast or the rainy West Coast, and to grow in harsh sun or dense shade. Most grass seed varieties grow well with full to partial sun, but new and improved versions will tolerate shade as well.
Buyers can often find specialized seeds within the same seed family. For instance, several options are available just within the fescue grass seed type. These include hard fescue that grows in colder climates and high elevations, creeping fescue that will grow even in deep shade, and fastest-growing grasses that withstands heavy traffic but doesn’t like hot weather.
The amount of seed necessary for overseeding a lawn depends on the type, whether the seed is coated or bare, and the overall condition of the existing lawn. The best rule of thumb is to follow the manufacturer’s coverage recommendations that appear on the bag of seeds.
The coverage area for coated grass seeds is not as high as uncoated seeds because coated seeds are larger, so fewer seeds are present per pound. Spread rate varies by grass type as well, and this will appear on the package. K31 fescue, for example, has a spread rate of 5 to 10 pounds per 1,000 feet, with 10 pounds being the average for establishing new lawns and 5 pounds as the average for overseeding. For the best results, follow the spread rate suggested by the manufacturer.
Keeping a lawn healthy and beautiful requires diligence and proper attention. Achieving a maintenance-free lawn isn’t possible, but you can reduce the amount of mowing, fertilizing, dethatching, and watering by choosing to overseed with a grass variety that grows well in the specific region. Generally, a low-growing grass variety, such as buffalograss, requires fewer mowings than a tall-growing variety, such as fescue.
If watering the lawn is a particularly tedious task, a drought-tolerant variety, such as Bermuda grass, is among the best options for a low-maintenance yard in warm, sunny climates. What is considered low maintenance in one region may be high maintenance in another, so consider choosing a variety that’s well suited or native to the area.
Our Top Picks
Before choosing a grass seed for overseeding, consider the type of existing grass in the lawn. If it’s growing well, overseeding with the same type is recommended. If the lawn is struggling to survive, sparse, and full of weeds or patchy, consider overseeding with a better variety to correct the existing problems. The following seeds are meant for different regions and lawns, but each is a standout in its category.
Our specially formulated grass seed, TurboTurf™, is high quality, weed-free, and offers high germination percentage rates. The best type of grass for you will depend on your climate.

Grows in Zones
When to Plant Grass Seed
Fall is best for planting cool-season grasses like Kentucky bluegrass, perennial ryegrasses, and tall fescues. Daytime air temperatures should be averaging between 60 and 85 degrees which translates to soil temperatures between 50 to 75 degrees. Spring is the second best option for cool-season grasses. Warm-season grasses, like Bermudagrass, Bahiagrass, Centipede grass, and Zoysia grass have the most successful germination rates in spring and early summer when daytime temperatures average about 80 degrees.
How to Plant Grass Seed
Test to be sure your lawn pH is between 6.0 and 7.4. Prepare the seedbed and broadcast your seed at the recommended rate. Keep it constantly moist by watering 2 to 3 times per day with a mist spray until germination.
How to Water Grass Seed
Water newly spread seed by lightly spraying 2 to 3 times per day. The goal is to keep the soil moist, but not wet. Once your grass has germinated begin to water heavier, but less often.
When to Overseed?
Late summer into fall and spring are good times to overseed northern yards with cool-season grasses. Southern lawns should be overseeded in the fall with cool-season grass.
How Long for Grass Seed to Germinate
Germination time varies amongst different types of grasses. Even the same seed will germinate at varying rates within different climates. Expect your grass to emerge within 7 to 21 days.

To determine whether a cultivar’s performance is truly different from another, subtract one entry’s mean from another entry’s mean. If this value is larger than the LSD value, the observed difference in cultivar performance is significant and did not happen by chance.
