How We Chose the Best Grass Seed

We interviewed Ryan Farley, CEO of LawnStarter, headquartered in Austin, Texas, to gain insight into what to look for in the best grass seed varieties. “I’d say climate and how shady vs sunny your yard is are both going to be essential considerations when you’re choosing a grass seed. Foot traffic is another important one, since if you do have a lawn that’s getting lots of traffic, you will want to pick a grass seed that can ultimately stand up to that,” advises Farley.  

With those considerations in mind, we researched the most sought-after grass seed products in their respective categories, keeping in mind their type, suitable season(s), intended use, and other special features

Kentucky bluegrass, ryegrass, and fescue are the most popular types of good grass seed for lawn maintenance among users because they are suitable in multiple climates and grow thick, durable grass. While not as popular, Bermuda and zoysia grass types are also viable options for those who live in southern areas with a lot of sun. Moreover, depending on your needs, these mixes can cover small or large yards. 

We also included grass seed types for overseeding to fix patchy areas on existing grass, as well as options for new plantings for your whole lawn. Plus, many of these options are mixes, which makes them easy to maintain without intense labor. For added convenience, select grass seeds in our list come with protective coatings to protect them from disease, aid in water retention, or have fertilizer built in. 

What to Consider When Choosing Grass Seed

When deciding which grass seed is best for front yard or backyard landscaping, it’s crucial to consider several important factors, including climate, maintenance, and sun requirements. A good grass seed should thrive in the specific conditions of your yard. Check below for some elements you should consider when purchasing the right grass seed. 

Types of Grass Seed

Grass seed falls into two main categories: warm-season and cool-season grasses. Warm-season grasses endure hot southern climates much better than cool-season grasses. During cold winters, warm-season grasses turn brown as they go dormant. Cool-season grasses grow quickly in the cool weather of fall and spring before going dormant in the summer heat. Warm-season grasses can be reseeded during the spring and summer, while spring and fall are the optimal time to reseed cool-season grasses. 

Warm-Season Grass 

  • Bahia: This warm-season grass is popular in hot climates because of its heat tolerance and drought-resistant qualities. While other grasses burn to a crisp in the hot sun, with its broad leaves and coarse texture, Bahia grass thrives. This makes it an attractive grass species in the Deep South. 
  • Bermuda: As with many other warm-season grasses, Bermuda grass thrives in hot climates thanks to its exceptional ability to tolerate heat and withstand high traffic. Bermuda grass requires good drainage, full-sun exposure, and plenty of nutrients. The grass does not tolerate cold weather well, making it a good option in the southern part of the country. 
  • Buffalo: Even though it is considered a warm-season grass, buffalo grass thrives in a broad range of climates and is quite common in states such as Montana that experience harsh winters. Like other warm-season grasses, it goes dormant and turns brown in colder weather. Planting season for buffalo grass is from April to May. 
  • Centipede: Centipede grass is known for being heat tolerant and very low maintenance. This makes it a popular grass for those who don’t enjoy spending a lot of time managing their lawns. Centipede grass thrives in full sun but will tolerate some shade. Due to those requirements, it does best in the Southeast. Plant centipede grass seed in the spring when all danger of frost has passed. 
  • St. Augustine: One of Florida’s most popular grasses, St. Augustine can tolerate high heat and humidity. It features blue-green grass blades that spread quickly through a lawn. St. Augustine also can tolerate salt water, which makes it a popular option for coastal yards. Since it spreads rapidly, one of the most effective ways to establish St. Augustine grass is by planting plugs. Plant St. Augustine seed in the spring or the summer.
  • Zoysia: Zoysia is a durable, dense variety of grass that’s known for its ability to stand up to heat, drought, and high foot traffic. Possibly the softest grass for bare feet, zoysia forms a dense lawn that chokes out weeds with very little maintenance required. Although some types of zoysia can only be grown from sod or plugs, some grass seed companies offer a variety that can grow from seed. Zoysia grass should be planted in the spring once the threat of frost has passed. 

Cool-Season Grass

  • Fescue: Tall, fine fescue grass seed is perhaps the most common grass type in the country. This is because it adapts well to many different climates as it tolerates heat, cold, shade, and drought reasonably well. This is primarily due to its deep roots that can reach as deep as 2 to 3 feet. Tall fescue is perhaps the easiest grass to grow, but it can suffer under heavy traffic. Plant and reseed fine fescue grass seed in the fall and spring. Shoppers will sometimes see fescue sold in all-season grass seed mixes, which claim they’re good year-round.
  • Kentucky bluegrass: This is the type of grass most people imagine when they consider the perfect lawn. With its lush, deep-green appearance, Kentucky bluegrass is a prized species. This grass is not easy to grow, requiring a high level of maintenance and care. Its shallow root system does not tolerate heat well, making it more suitable for northern lawns. Kentucky bluegrass should be planted and reseeded in the spring and fall. 
  • Perennial ryegrass: Perennial ryegrass should not be confused with annual ryegrass, which is a temporary grass used for erosion control. Perennial ryegrass comes back year after year. Ryegrass germinates quickly, making it popular for new lawns. It does best in colder climates with mild summers; however, it can still be found in the southern part of the country. Perennial ryegrass should be planted or reseeded in the fall. 

Climate

With enough determination and money, you can grow most of the above grass seeds anywhere in the country. It’s not uncommon to see beautiful Kentucky bluegrass lawns in the baking heat of the Southwest. Going against climate guidelines will make the job much harder and more expensive, requiring significant investments in irrigation systems, water, and fertilizers. Paying attention to climate will make establishing a lawn much more manageable. Consider where you live and what grass types will thrive in your region with minimal maintenance and watering. 

Reseeding vs. New Planting 

How you go about reseeding a lawn versus planting a new lawn is quite different. When seeding a new lawn, you’ll apply seed to the bare dirt you’ve prepared for new planting. According to Farley, applying grass seed for overseeding is a much easier process. “Pretty much all I recommend here is raking or dethatching to remove any layer of debris so your seed can reach the soil directly, then watering thoroughly to ensure the seeds get into the soil and have the moisture they need to germinate.”

With that in mind, you typically need about twice as much seed to start a new lawn as you need to overseed an existing lawn

Traffic Level 

Different types of grass vary in how well they tolerate foot traffic. If you have kids or pets and plan to use your backyard extensively as an area for play, consider selecting grass types that can take some abuse and still keep on growing. Zoysia and Bermuda grasses are the most tolerant of foot traffic, while fescue does poorly with heavy traffic. 

Required Maintenance

While some property owners enjoy fussing over their lawns, many homeowners dread long hours spent maintaining a yard. Consider which types of grass require the least care and how much work you’re willing to put into a lawn. Zoysia grass, for example, requires annual dethatching, while perennial ryegrass will not self-repair and requires patching. Bermuda grass, in comparison, is a low maintenance lawn grass.

Also, keep in mind that regardless of the type, newly planted grass seed needs watered. The best time to water grass is early morning, but many varieties require twice per day waterings until germination. 

Sun Exposure 

Various grasses tolerate different levels of sun exposure. Some grasses, such as Bermuda grass, demand full sun, but other varieties, such as tall fescue, do well with partial shade. Assess the sun exposure of your lawn to determine a good lawn grass seed for the lighting conditions there. Some seed companies produce specific seed mixes, such as grass seed for shade, full sun, or lawns with shaded areas and full sun areas. 

Single Seed vs. Mix

When selecting a type of grass seed, you can choose one specific seed type or a blend that combines several different species. Go for a single seed type if you’re trying to achieve a particular look for your lawn. While single seeds are more difficult to maintain, the effect of a single-species lawn can be well worth it. 

Mixes are easier to grow and maintain because companies blend the mixes for improved drought or heat tolerance. They also generally grow more uniformly with little need for patching.  However, your lawn will lack the attractive uniform look of a single-species lawn. 

Germination Percentage

Despite your best efforts to prepare your yard for seeding, some seeds simply weren’t meant to become plants. This is where germination percentage comes into play. Germination percentage is a measure of the viability of a collection of seeds. It is calculated by dividing the number of seeds that germinate by the total number of seeds. 

Given how much grass seed can cost, the higher the germination percentage the better, and it mostly relates to seed quality. Although you might be tempted to buy the cheapest grass seed on the shelf, chances are it will have a lower germination percentage, resulting in significant waste. High-quality grass seed has a 90 to 95 percent germination rate, making it worth the additional investment. 

Grass typically germinates within 5 to 30 days. However, If you’re wondering how long it takes for grass to grow to maturity, that depends on the variety. Cool-season varieties grow faster than warm-season grasses. No matter what you choose, you’re likely to have a mowable lawn within two months of planting.

FAQs

If you’re still wondering what product is best for you, read on for answers to your most pressing grass-seed questions. 

Q. What month is best for planting grass seed?

The best month for planting grass seed is September for cool-season grasses and May for warm-season grasses, although when to plant grass seed can vary depending on where you live. For cool-season grasses, you want a combination of warm soil, moderate temperatures during the day, and cool temperatures at night. Warm-season grasses should be planted when temperatures eclipse 80 degrees during the day and remain warm through the night. 

Q. How do you seed a lawn?

Once you’ve purchased your seed, you’ll need to prepare the soil. If reseeding to fill in the lawn or patches of dead grass, cut the grass to a height of 1.5 to 2 inches. Lightly rake the area to break up the soil’s surface, so it can receive the seeds. For new lawns, prepare the ground, making sure to even out the surface. Use a spreader to distribute the recommended amount of seed for reseeding or planting a new lawn. 
 

Q. How do you prepare ground for grass seed?

If possible, use a soil test kit to determine the pH of your soil. Depending on the results, you might need to add organic matter such as lime, compost, topsoil, or peat moss to your soil. Once you’ve completed that step, break up the top ½-inch of the earth with a rake. The soil needs to be loose to accept the seeds.

Q. Can you mix grass seed with topsoil?

Mixing grass seed with topsoil is not a good idea. By combining the two, it’s difficult to spread the seeds evenly throughout the yard. It also might cause some seeds to be buried too deep into the soil to germinate and grow. For better results, spread the seed after mixing topsoil into the yard. 

Q. Do you need to cover grass seed?

It’s best not to cover the grass seed with topsoil. Grass seeds are not strong enough to push through heavy earth after germinating. Covering the seeds with topsoil suffocates them, preventing them from growing.
