Do you have a shallow lawn and wonder if you can grow grass on it? Many homeowners are faced with shallow lawn conditions, and the problem is more common than you may think. Today we are going to learn if grass will grow in 2 inches of soil. So, if your topsoil is shallow, you might want to pay close attention to the information below.
Will Grass Grow In 2 Inches of Soil
The answer is yes, grass will grow in 2 inches of soil. For those with shallow lawns, this may seem like great news. However, the truth is grass may grow in shallow soil, but it won’t grow to its full potential. As you will learn below, growing grass in shallow soil can be a recipe for disaster.
Why It is Not Wise to Grow Grass in Shallow Soil
If you choose to plant grass in 2 inches of soil, the following things can happen. Keep these conditions in mind when choosing to plant grass in shallow soil.
Heat and Cold Damage
Grass that is planted in shallow soil will be prone to heat and cold damage. When grass doesn’t have enough soil to spread out, the root system will be closer to the top of the ground. During periods of high heat and extreme cold, the roots of the grass can be damaged. This can stunt the growth of grass and can even kill it in some situations.
Poor Moisture Control
Shallow soil doesn’t provide enough room for moisture to build. Most grass varieties need a good amount of moisture to survive. Because grass grows so quickly it can use up much of the moisture in the soil. For those will shallow lawns, you will need to water the grass daily to keep it from turning brown.
Lack of Nutrients
Lack of moisture is not the only thing you have to worry about with shallow soil. Soils that are 2 inches deep or less have fewer nutrients and can’t provide enough food for grass to thrive. The grass may sprout in shallow soil, but it won’t provide you with that lush lawn you are looking for.
Slower Growth
If you want your grass to grow fast, then you should never plant it in shallow soil. As mentioned above, shallow soil has fewer nutrients and contains less moisture. This will stunt the growth of grass, and your lawn will not look its best. Planting grass in deeper soil will provide it with enough of the things needed to become lush and green.
Erosion Issues
Erosion is another real issue that shallow soil presents. When grass can’t develop deep root systems rain can wash the soil away. Eventually, this will cause the grass to turn brown and die. This will make your lawn look like a desert. Having a bad-looking lawn is often frowned upon, especially if you live in a neighborhood with a homeowner’s association.
4 to 6 Inches of Soil Is Best
Now that you know grass won’t thrive in 2 inches of topsoil, you might be wondering how much dirt you need. Most grass varieties do best when planted in soil levels of at least 4 to 6 inches. This level of topsoil will give your grass plenty of room to establish a strong root system. Having a well-established roots system is the key to a beautiful lawn.
Adding Topsoil
The best way to get the dirt you need to grow grass is to bring in some topsoil. If your lawn is small, you will be able to bring in topsoil by the bag. Bagged topsoil is easy to spread and this can be done by hand. If your lawn is large, you may need a few truckloads of topsoil to build up your lawn. For those of you that need more than a little topsoil, it is best to hire a landscaping professional to do the job for you. They will have the tools needed to get the job done right.
