How To Choose the Grass Seed For Clay Soil

Here is a list of the things you should consider in order to buy the finest grass seed for clay soil –


One of the most important things you should keep in mind while purchasing grass seeds is what season you are choosing them for. There are cool-season grasses as well as warm-season ones, and you should go for a type depending on the climate of your area.

Cool-season grasses are tolerant of extremely cool temperatures and often grow in even snow. The most popular grasses of this kind are the Kentucky Blue Grass, the Perennial Rye Grass, and the Tall Fescue Grass. These types of grasses grow best if they are planted during Fall.

Warm-season grasses tend to be able to tolerate high heat and are usually drought resistant. They are best suited for areas where lawns lay brown and dry for months due to lack of proper care.

Some of the most popular grass seeds of this type are the Bermuda Grass, the Zoysia Grass, the Centipede, the St. Augustine, the Bahia Grass, the Buffalo Grass, etc. These types of grasses are best when planted in early Spring.

Type of Seeds

Are you looking to plant only one kind of grass across the whole desired area, or a blend of different grasses? Depending on that, you should make your choice of whether you will purchase a straight seed or a mixture.

A straight seed has only one type of grass seed in it and is usually used for a uniform, even look – E.g., golf fields. A mixture is a blend of different grass seeds and is used when you need to combat several problem areas at once, or need the benefits of all of them.

Most people usually go with mixed seeds, as it has a lot of variety in a single blend and offers a lot of features like drought resistance, insect protection, durability all in one. This is something you do not easily get with a straight seed.

Traffic Resistance

If you are looking for the best grass seed for clay soil, then you got to take this feature into account.

One of the things lawn owners worry most about is how much traffic their grass can withstand. This is a special area of concern for those who own pets and kids because it seems like there is no amount of restrictions that can stop them from playing around on the lawn.

Therefore, look for grass seeds that are highly traffic resistant, so you can get the joy of both a beautiful lawn and the scenery of watching your children and pets play.

Sun VS Shade

While some grass seeds are specially formulated to work under full sun, others are better suited for medium to dense shades. Take a good look at the place you want to get some grass on, whether it is sunny or shady, or maybe even a bit of both, and then make your choice.


Some people prefer the feeling of soft, thin grass under their bare feet, while others are just looking for something coarse in texture to withstand traffic. Whichever type you prefer, buy that kind of seed.


A lot of grass seeds packets have other fillers mixed in them, and also weed. While it is okay to have about 0.5% weed mixed into the grass seeds, it is best to choose grass seeds with no additives mixed in them. These kinds of seeds result in better-growing grass.


Some seeds will require constant care and attention in order to grow properly. You will have to use fertilizer, water the seeds every day when they are germinating, and so on. And let’s not even go into the details of the care they need once they have grown properly.

Other seeds, however, may not need as much maintenance as those. So choose only the kind you are comfortable with, and you will be doing yourself a favor.

How to Grow Grass Seed in Clay Soil

The following steps will help you grow the grass seed in clay soil.

Step 1: Check the Soil Density

You should be able to determine how dense the soil is to prepare it for the next steps. While standard tests are available, it can be done by you just as easily. Simply take around a fistful of soil in your hand, and add 2 to 3 drops of water.

Create a small ball with that soil, and try to press it into a long stretched ribbon. If it breaks before reaching 2 inches, it is one of the less dense types of clay. If it reaches 2 inches, it is heavier clay.

Step 2: Amend the Soil

Now that you have tested the density of your lawn, you should try to prepare it for the plantation process. For this step, follow the processes mentioned below-

Step 3: Keep the Grass Clippings

Step 4: Mulch Leaves

Step 5: Add Organic Fertilizer

An organic fertilizer will release the necessary nutrients into your soil, and get it all prepped and ready for your freshly bought grass seeds.

Step 6: Aerate

Aerating the lawn will help to make sure that all the organic compounds you have been tossing in, really gets to make their way through to the soil. The benefits are quite amazing, so definitely do this.

Step 7: Retest

Do a density test on the soil again after 2 months. The goal is to make sure that the soil is not too dense, and if it is, go through another stage of layering it with organic compounds.

Step 8: Take Measurements

Measure the area that you want to plant your grass on, and determine how many packets or how much seed you will need. Most packets of grass seeds come with specifications as to how much area they can cover, and some are resealable so you can use the rest later after one use.

Step 9: Provide Moisture

Once you have finished planting the grass seeds, water the area using a sprinkler at least once a day, watering it twice is best for normal climates. Just make sure it is not oversaturated.
