Popular 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 the winter, 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.
- 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 with those who don’t enjoy spending a lot of time managing their lawns. Centipede 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: As its name suggests, St. Augustine is one of Florida’s most popular grasses. This is because it 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 summer.
- Zoysia: Zoysia is a tough variety of grass. It’s known for its ability to stand up to heat, drought, and high foot traffic. 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.
- Fescue: Tall fescue grass 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 a root system that can reach as deep as two to three feet. Tall fescue is easy to establish but can suffer under heavy traffic. Plant and reseed tall fescue in the fall and spring.
- 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, 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.
What to Consider When Choosing the Best Grass Seed
When deciding which grass seed is best for your lawn, it’s crucial to consider several important factors, including climate, maintenance, and sun requirements. Check below for some of the elements you should consider when purchasing grass seed.
With enough determination and money, you can grow most of the above grass seeds just about anywhere in the country. It’s not uncommon to see beautiful Kentucky bluegrass lawns in the baking heat of the Southwest. But going against climate guidelines will make the job a lot 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 be applying seed to the bare dirt you’ve prepared for new planting. For reseeding, you’ll be attempting to thicken an already existing lawn. With that in mind, you typically need about twice as much seed to start a new lawn as you need to reseed an existing lawn.
Grass types 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.
While some property owners enjoy fussing over their lawns, many homeowners dread long hours spent maintaining a yard. Consider which grass types require the least amount of 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, requires very little maintenance.
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 and determine what kind of grass seed you should use. Some seed companies produce specific seed mixes for full 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.
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 a cheaper bag of grass seed, 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.

FAQs About Grass Seed
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 this 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, 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 lyme, compost, topsoil, or peat moss to your soil. Once you’ve completed that step, break up the top 1/2-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.
