How to Grow Grass on Hard Dirt

The following steps may prove helpful if you want to grow grass on hard dirt:

Step 1: Soil Test

The most crucial step is to work to improve the soil by understanding its composition. You can bring your soil to a laboratory where they will tell you whether it has heavy clay, sand, or organic matter.

Through this soil test, you can also know the presence of nutrients in the soil and use fertilizers if there is any nutritional demand. Once you get all the information about the soil, it will become easy to proceed with planting grass. In addition, ensure that the soil’s pH ranges between 6.0 to 7.0.

Step 2: Aeration of the Soil

The rugged and compact soil doesn’t have air pockets and will not allow nutrients and water to flow through the surface. Due to this, you may need to make air pockets. It is essential for your grass seeds as the aeration of the soil helps them to develop and grow healthy roots. It is easy to aerate the hard soil using a core aerator. A core aerator is a machine that has the exact size of a lawnmower, and it is readily available in the local garden center. 

Through this aerator, you can pull small plugs of dirt and create air pockets. In this way, you can push it all over the lawn. However, if the soil is tough, you may need to till it. When you till the hard soil, it will break up to six or ten inches, making it more workable. You can do this job easily with the use of a rototiller. In this way, you can create more air pockets so that the grassroots grow and develop better.

Step 3: Add Composite

Adding composite is a good option. It is advisable to increase the nutritional power of the soil after aeration. Spread a layer of compost on the surface, and use a tiller once again to mix in the soil. The organic matter or compost will be incorporated into the soil. It will help to increase the nutrition ability of soil for a long time because, with time, the compost starts to break down and enhance nutrients in the soil.

Step 4: Combine Some Fertilizer

You can also combine fertilizers when adding organic matter to the soil. For this, you can pick up organic fertilizers like concentrate or animal manure, as they can boost the growth process of grass seeds. When this compost or fertilizer starts to break down, it will increase the soil’s ability and feed grass seeds for their growth.

Step 4: Level the Soil

When you mix the fertilizer and compost in the existing soil, start to level the surface or purchase topsoil. However, you may need to do this more than one time to get better results. It is also good to let and rest the soil settle down because you will get time to see the bumps and dips in the surface. For leveling the surface of your lawn, you can use a lawn roller for the final finish.

Step 5: Selection of Seeds

Good quality seeds are essential for the better growth of your lawn grass. Keep the quality of seeds high if you want a lush green lawn. If you get old or cheap seeds, most will not germinate and leave bare patches on your lawn.

Step 6: Spread Your Seed

After selecting quality seeds, spread them on the prepared soil. If the lawn area is small, you can quickly spread them by hand broadcast. For a big lawn, you can use a seed spreader. The grass seeds must have contact with the soil for germination. For this, you can give a light crack and add a thin layer of topsoil to cover the seeds. 

However, the roots of the seed may run out of energy before the shoots come out of the soil. So don’t bury the seeds too deep into the soil. The grassroots doesn’t require deep topsoil as the roots are only two to three inches long.

Step 7: Add Water

Take care of the water requirements of your newly planted grass seeds because they need to remain moist for germination. You can water your grass seeds early in the morning and evening before the sun goes down. Remember that don’t give them an excess of water; keep the soil moist so the seeds can start germinating. Keep watering twice a day until the grass sprouts start to come up.

Reduce the frequency of water whenever you see fresh grass coming out of the soil. However, at this stage, the water is a little deeper. Follow the below steps for watering grass: 

• After planting, keep the soil moist for this water 2 to 3 times daily.
• When grass becomes 1 inch tall, water it daily or when required, and saturate the topsoil when you water.
• Reduce watering to once or twice a week and try to water more deeply to encourage root development.
• Once the grass becomes fully established, water it according to the needs of the grass variety. Keep watering infrequently but deeply.

Step 8: Mow Your New Lawn

Mow your lawn when the grass height becomes up to three inches. Only take off one-third of the grass and set the mower’s height according to this. Ensure the blades of the mower are sharp enough to give the grass a clean and excellent cut.

Step9: Do Not Walk on Newly Seeded Lawn

Don’t walk on a newly seeded lawn even light foot traffic can damage newly germinated grass seeds. So remain away from the new grass so it can be established well. Moreover, you can compact your lawn if you keep walking on it, especially avoid walking when the surface is damp.

Grasses for Hard Soil

Some species of grass can grow in hard soil. You can consider one of them as they have better chances of success. The weather conditions of your area also determine the types of grasses. The following grasses are an excellent choice for hard soil:

1. Buffalo grass
2. Bermuda grass
3. Fescue grass

However, carefully choose the type of grass and consider the climate conditions of your environment. It becomes more important when you plant grass seeds in hard dirt. The best grass for your hard dirt can accumulate in heavy clay soil because it is very dense.

Before starting with any grass variety, figure out how much your lawn can receive sunlight and then look at the type of grass according to your local temperature and weather. Remember that all grasses cannot bear heavy foot traffic, so consider how you want to use your lawn. The following options can give you help with the selection of grass type:

Fast Growing Grass Type

Good results only depend on the correct type of grass. Some grass types can grow faster than others. There is a need for a little effort, and things will happen speedily. The following grasses tend to grow the fastest:

• Tall fescue
• Bermuda grass
• Zoysia grass
• Centipede grass

Cool Season or Warm Season Grasses

You should be well informed about the climate conditions while choosing the proper grass type. There are a lot of varieties of turf grasses that have to be categorized as cool-season and warm-season. You can choose according to your needs. Most of these grasses are also compatible with hard dirt but consider your weather conditions. If you live in cool areas and have hard dirt, go for fescue. And if you live in warm areas, Bermuda, Zoysia, and Centipede are the best recommendations.

How Long for Grass to Grow in Hard Dirt

The time of growth mainly depends on the type of seeds you use. However, here is the germination period of different grasses.

• Tall Fescue: 4 to 14 days
• Bermuda Grass: 7 to 14 days
• Zoysia Grass: 14 to 21 days
• Centipede Grass: 14 to 28 days

Prepare the hard soil before planting and keep it moist, as it is essential for germination. If the soil becomes dry, it will affect germination and slow growth.

On-Going Lawn Maintenance

Keep working on the hard dirt to make it smooth in texture, which will also affect the overall quality of the soil. It is also a fact that hard dirt tends to return to its initial stage if you don’t care about its proper maintenance. Due to the high clay content, it can re-hard with time, so don’t leave it alone.

The compost or organic material is suitable for getting the desired weight and texture. Spread a thin layer on the surface and then sow the grass seeds. Once the compost breaks into components, it will increase the number of nutrients in the soil. Make a schedule for the aeration of your law so that the soil will introduce fresh oxygen and water. Mostly aeration once a year is enough for the excellent performance of the lawn and the best time is early fall.

Keep furniture and heavy gear away from your lawn and do not drive or park vehicles. In this way, you can increase the life of your lawn. Moreover, if you notice that the section of your grass is dying when you place something heavy on it, it may cause compaction damage.

( Expert Tip: Some factors can affect grass seeds’ growth, so ensure proper treatment of these factors. For this, choose seeds and conditions according to your environment. The most important factors that can affect growth are sunlight, temperature, and seasons so keep them under consideration.)
