It’s root system can grow six inches deep. It’s also fibrous, which makes it able to survive the slow-draining clay soil.
This is a warm-season grass. It goes dormant during winter and is revived during spring. This is probably the warm-season grass that thrives best in clay soil.
Bermuda is resistant to drought, which makes it even more ideal for clay soil during summer. It is also impervious to most weeds and pests.
This is a perennial grass that has a deep root system. It’s so deep it could grow as much as one foot.
That makes it really ideal for clay soil. It can withstand compaction, which is essentially a common characteristic of the clay soil.
As soon as the lawn has been established, the buffalograss won’t need too much irrigation.
However, this warm-season grass would need an inch or two of water every two weeks during drought.
Most cultivars will go dormant during winter.
Ready to plant grass?
Now that you have the list of the three best types of grass to grow in clay soil, it’s time to go through the process.
How to Grow Grass in Clay Soil
While there are plants that grow in clay soil, it is still important that you actually make this type of soil less dense.
You have to somehow treat its compaction issue.
1. You need to integrate organic matter into the soil
Preferably, you should do this about two months before planting the grass. You need time to really improve the soil structure.
This part is going to take a bit of work. However, after this, you only just need to do some maintenance work to ensure that the much-improved clay soil will stick.
What to do first?
You should remove whatever plants or weeds are in the soil. When that’s done, then you can already put in the organic matter.
For the best result, you should put in around six to eight inches of organic materials.
Organic matter to put:
You just spread the organic matter on top of the soil. Then, you have to integrate it into the topsoil, which could be a minimum of six inches or as much as one foot.
The deeper you can go, the better.
Yep! It’s hard work
You can simply use a shovel or a tiller, which would be better for your back.
The soil will only get better from there. You see, microorganisms will break down the organic matter and the soil structure will surely be improved.
2. Plant your grass seeds
We’ve mentioned three types of grass that would thrive in clay soil. Or you might have your own choice anyway.
Read the instructions on the label of your grass seeds. There are appropriate ways to plant different types of plants.
For easy work
You can use a seed spreader in order to plant your grass seeds into the clay soil.
3. Water generously
Remember that the clay soil has been treated, so it’s no longer as slow-draining as it should be. Also, you are still trying to establish the grass.
The grass seeds would need an abundance of water in order to germinate.
Again, look at the instructions
The label will tell you how to grow the grass seeds. As a rule of thumb for grass in clay soil, water the area with about one-fourth inch of water twice a day.
As soon as the grass has been established, you can water it as needed.
4. Soil maintenance
Test the soil every season and treat it accordingly. If the pH level is not up to par, then you can increase or reduce it appropriately.
If the soil is deficient in specific nutrients, then you can add those as well.
You need to continue this:
Add organic material when you can.
Clay is not the most ideal soil for growing plants or grass. That doesn’t mean that it’s impossible. First, there are types of plants that thrive in clay. Second, there are ways to improve clay.
The issue with clay is that it’s too dense. It will drain water really slowly. Then, during the summer, the area will have cracks. In order to ensure that you will have really healthy grass and a beautiful lawn, you should find the best type of grass for clay soil.
Then, it’s just about knowing how to grow grass in clay soil. The first part is going to be hard work since you will need to put organic matter into the clay soil. But things will only be easier from there.
