What Are Grass Seeds?
Grass seeds are simply seeds that grow grass. Grass seeds grow in several different growing conditions, and grass seeds come in many different types as well. The type of seed you plant will be very important. Depending on where you live, the grass seeds may or may not make it. Let’s look at some of the grass seed types and which one you need for your home.
Grass Seed Types
There are many grass seed types, and they grow in varying regions across the world. Here are some of the most common grass seed types.
Cool Season Grass
Bentgrass is a very popular grass to find on a golf course. In the northern United States, you can cut bentgrass very short, and therefore it’s perfect for a golf course. Bentgrass is an expensive grass to maintain; when it is so short, the insects and funguses can start to take off.
Warm Season Grass
Bermuda grass can tolerate a very low mowing height, which makes it good for golf courses. Bermuda grass needs to be fertilized and watered quite often, especially when it gets hot out. Bermuda should be deep green, but sometimes it is much lighter.
Warm Season Grass
Centipede grass grows horizontally, which is what sets it apart from some of the other grasses. Although this is a warm season grass, it does not do well when it gets dry. You will find Centipede in the south on the northern coast, where it is a bit more humid.
Cool Season Grass
Fescue grass is quite popular, and if you are planning on planting an entirely new lawn, the fescue is a popular choice. The fine fescue is a thin textured grass that does well in the shade. The cooler conditions and moist weather seem to be the best fit for fine fescue.
Cool Season Grass
Kentucky bluegrass is one of the more popular types of grass in the north. In fact, if you live in the North, you have probably purchased some Bluegrass sod at some point. Bluegrass tends to spread quickly and is relatively easy to keep alive.
Cool Season Grass
Ryegrass is a cool season grass that is soft and dark green. When you mow, Ryegrass looks a bit white when you are finished. Although this is considered a cool season grass, it doesn’t do well in areas where the temperature never fully warms up. Bluegrass seems to be a more popular northern grass
Cool Season Grass
Tall fescue is another type of fescue that does very well in high impact areas. You will notice tall fescue on sports fields, and it grows in thick bunches. Tall fescue grass is often mixed in with other seeds to complete a seed mixture.
Warm Season Grass
Zoysia is a grass type that is growing in popularity across the south. With the ability to purchase seed and grow this grass easily, it usually turns out to be a better choice than St.Augustine. The only downside of Zoysia seed initially is that it is slow growing; sometimes, it can take up to a year.
Grass Seeds By Region
There are two basic regions when you start talking about grass seen. There are cool season grasses and warm season grasses. Depending on where you live, you will need to understand which seed can grow where you live. If you plant a warm season grass in a cool season zone, it will not last through the winter.
Cool Season Grasses
Warm Season Grasses
- St. Augustine
Considerations When Buying Grass Seed
Now that you have a better understanding of the best grass seeds on the market, how will you know which one will be the best for your yard? Aside from the type of grass, you must make a few other considerations before purchasing lawn seed.
The most important consideration is what type of grass you are going to want in your yard. Most people like to have grass that matches across their entire yard. This is not just for aesthetics but also for keeping the lawn in great shape.
When you have different types of turf, you may need to adjust your watering and fertilizing schedule. If you are unsure of which type of grass you have, you can use an online guide from a seed company to determine what you have.
Location of Seeds to Be Planted
Once you identify the type of lawn seeds that you want, you must consider where you will be planting the seeds. Is the grass in a full shade area, partial sun, or full sun? Try and watch the areas that need seeding for a day to two to establish what is necessary.
When you don’t pay attention to the light in the area, you will have difficulty getting the grass to come up.
The price of grass seed seems to be all over the place. Many of the southern grass seeds are much more expensive than the cooler season grasses. Part of this is that they are a bit harder to grow. When it comes to home lawns, you don’t want to have to seed all that often. Paying for a high-end seed, to begin with, will help to make sure you get a stable and healthy lawn.
How much of your lawn needs to be covered with seed? Certainly, if you are putting a new lawn in, you will need quite a bit of seed. However, if you are just fixing up some bare spots, you may save some money by purchase a smaller bag. Lawn seed will have a shelf life; if you don’t need a 50lb bag, don’t buy one!
Best Time to Plant Grass Seed
Knowing when to plant grass seed and understanding the importance of growing conditions will ensure that your seed purchase is not waisted. There are good times in the spring and fall to plant the seed, and sometimes in the summer as well.
When to Plant Grass Seed in Spring
Warm season grasses are going to do the best when they are planted in the spring. The spring temperatures and soil temperatures are warm enough for the warm season grasses. They will also have the entire summer to grow and gain strength before temperatures start to drop.
Warm soil helps the seeds start to establish themselves. We recommend waiting until you start seeing some 80 degree temperatures before you start your planting projects.
Planting Grass Seed in Fall
Cool season grasses tend to do best when planted in the fall. Although this can be a long wait to fill in, it is truly the best time to plant these seeds. You will want to wait until the daytime temperatures start to drop. However, always give your new seed about 35-50 days before it will experience its first frost.
Your first frost time will depend on your location, but most of this information should be available on a local weather app. The early fall is usually the best time for these grasses.
Planting Grass Seed in Summer
Planting grass seed in the summer is not ideal. Summers tend to be quite dry and hot, and most of the time, these are not great characteristics for getting a green lawn. If you are going to plant grass in the summer, make sure that it is warm season grass. Pay very close attention to the water that you are giving your new seed. Although you want to keep it moist, too much moisture can cause fungus.
How to Plant Grass Seed
Planting grass seed is not difficult, but making sure that you do it correctly will help ensure that your money on grass speed was well spent. Here are the important steps to follow.
1) Prepare the Soil
It is important to make sure that your soil is prepared before you start putting your seed in the ground. It is good to rake up and turn over about two to three inches of soil before putting your seed down.
2) Spread Seed
Next, you can spread your seed by hand or spread it using a spreader. If you are dealing with a larger lawn, you will want to use the spreader to make sure that the entire lawn gets covered.
3) Cover Seed
This is the step that most homeowners forget to do. Once you plant the seeds, you need to put about a 1/4 inch of soil over the top. If you don’t do this, your seed will be much too exposed, and it won’t have a chance to grow properly. Do not forget this important step.
Once you have completed these steps, add some water to the equation. Follow the watering recommendations very closely when you are seeding a lawn. Depending on the type of grass you are planting, you will need to adjust your watering protocol.
Grass Seed FAQ
What Is the Best Grass Seed?
The best grass seed is the one that is going to grow well in your area. The problem with choosing one type of seed as the best will make people think that it could work on their turf. If you live in a cool season area, people have quite a bit of luck with Perrenial Ryegrass. The ryegrass is easy to grow, and it will start turning your lawn green in a matter of weeks.
How Much Grass Seed Do I Need?
To determine how much grass seed you need, you will need to know the square footage of the area that you are covering. When you look at the grass seed, you purchase they will tell you how much square footage it will cover for newly seeded turf and fill in bare areas. When you fill in or oversee, you need much less than when planting a new lawn.
Does Grass Seed Go Bad?
Grass seed will go bad. As you may remember, one of our considerations when purchasing seed is to make sure you don’t purchase too much. When you buy a 50-pound bag of seed and only use two pounds, you may have to spend a lot more than you need to.
Grass seed will last for about two years after you open the bag; however, it will never be as effective as when you first open the bag. We recommend using the entire bag of seed when you first purchase it.
How Long Does Grass Seed Last?
A bag of opened grass seed that is left covered in your garage should last for about two years. Sometimes it will last for three years or more, but it tends to lose its effectiveness. If you are going to purchase grass seed, use it when you get it.
Will Grass Seed Grow if You Just Throw It on the Ground?
There is a chance that grass seed will grow if you throw it on the ground, but it is not the most effective way to plant grass. The problem with throwing grass down like this is that it will have a hard time rooting in the turf. Unless your soil is very soft and easy for the seed to penetrate, the seed will struggle.
Additionally, if you are not watering and keeping an eye on the seeds they will not thrive. As such, we would like to throw some seed down and walk away; it’s not a guarantee that this will work.
How Often to Water New Grass Seed?
Depending on the type of seed you plant, you will likely need to water your grass seed daily. From our grass seed reviews, you probably noticed that the new seeds are being designed with the capability of retaining more water.
The grass that you purchase will have a recommendation for how often to water, and you should follow it closely. Never water so much that the seeds start to wash away. Take into account that rain needs to be considered as watering as well. New grass seed truly needs to be babysat until it establishes itself.
How to Plant Grass Seed on Hard Dirt?
If your dirt is very hard, you will have to add a few steps before planting your grass seed. The soil needs to be turned over so the grass can take root and start to grow properly. You can do this by hand, or you can use a rototiller to complete the project.
How to Plant Grass Seed on Existing Lawn?
Planting grass seed on the existing lawn can be a great way to improve your lawn’s health and thickness. If your grass is nice and thick, it will resist weeds much better. When planting grass seed on existing grass, be sure to rake out the current lawn.
If you can do a light aeration of the turf, this is another great way to grow seed in your current lawn. After adding the seed to the turf, try to cover it with a light layer of topsoil. As always, make sure you are then watering your turf generously. As long as you rake and prepare the room for the new seed to fill in, you won’t have problems growing grass on existing lawns.
Will Grass Seed Germinate on Top of Soil?
The step that many people like to skip in the grass growing process is covering up the seed with soil. Some durable grass seeds will still germinate on top of the soil, but this will happen much slower, and the grass will not spread nearly as fast. Although the grass seed can germinate on top of soil, this is not the best way to protect the money you just spend on a bag of grass seed. Follow the proper procedures to get the most use of the see you have just purchased.
Recap: Buying and Planting Grass Seed
At this point, you should have everything you need to purchase and plant new grass seed this season. There is something pretty special about having green grass and a full lawn. Whether you are putting in a new lawn or trying to work on areas with high foot traffic, planting grass seed is a skill all homeowners need. Always make sure you pick a product that will work with your soil, location, and climate. If you follow the proper steps, you will have a lush and healthy lawn in no time.
