5 Best Grass Seeds for Sandy Soil
1. Tall Fescue Grass
Tall fescue grass is one of the most common cool-season grasses that are highly adaptable and are able to grow in a wide range of soils. They grow slowly, are relatively low maintenance, and will flourish in shade and sunlight with their best growing season during fall and spring.
Tall fescue grass has a deep-rooted structure which means it can retain water and is resistant to drought. For sandy soils, creeping red fescue and hard grass is the best grass for sandy soil because it easily fills up a patchy or empty lawn. Here is a great example;

2. Bermuda Grass
Bermuda is a warm-season grass that flourishes in sandy soils because it requires well-drained soil with less water content. Unlike other warm-season grasses, the Bermuda grass grows very fast. Although the grass takes a bit of time to establish, it spreads quickly to create a dense turf.
However, the Bermuda grass will need a lot of sunlight to grow and might suffer if placed in a shady area. On the other hand, it is drought-resistant, might go dormant during the winter seasons, and come back to life in summer and spring. The two main types, Yukon and Riviera, have great drought and cold tolerance.

The germination of Bermuda grass seeds takes about seven days. However, if the planting occurs late or early in the season, the grass might require more time to germinate well in sandy soil. This grass has a medium-fine leaf texture and a dark green color.
3. Centipede Grass
Centipede grass is a low-maintenance type of grass since it won't require a lot of watering, which makes it ideal for sandy soil. It is also a warm-season grass that flourishes in the summer and spring seasons.
Centipede grass boasts excellent heat resistance properties. However, in comparison with other warm-season grasses, it has a shallow root system. Moreover, it spreads via above-ground stolons instead of underground rhizome, creating a thick carpet-like sod.

4. Zoysia Grass
Zoysia grass is categorized by USDA for use in plant hardiness zones six to nine. It is one of the great grass for sandy soil as it forms deep roots that help in absorbing water and nutrients. Zoysia grass is also well adapted to drought areas with very little water requirements.
However, Zoysia grass may develop slower than other grasses but will grow faster when well fed with a fertilizer that has nitrogen and phosphorus for proper root development. If you decide to use this type of grass on sandy soil, ensure that you're not using the Meyer variety or Z-52 because it is susceptible to nematode infestation.

Why Do You Need the Best Grass for Sandy Soil?
If you live in places with sandy soils, you probably understand how challenging it is to plant grass or anything there. However, with the right soil modifications, the sandy soil garden can become a beautiful place full of green grass.
It is crucial to note that the structure of the sandy soil will differ depending on the texture, color, and water retention of the soil. To determine the content and quality of the soil, you can use a soil pH tester or feel it.
Generally, sandy soil is made up of eroded and broken rocks that consist of large particles that create large spaces between them. This makes the water retention poor, and it means that the water and nutrients will easily be washed away, making it hard to grow in sandy soils. This is why you need grass seed options that can thrive in sandy soils.
How Do You Grow Grass in Sandy Soil?
Grass growing in sandy soil is not very difficult with the right method. Here are a few tips on how you can prepare the land to ensure the type of grass you're growing flourishes;
- Remove the weeds, big rocks, and debris from the soil
- Dig about six inches deep using a rake, then add the organic material and spread it equally on the soil.
- Instead, you can invest in fertilizers to improve the rate of plant growth. Coat the planting area with fertilizers and make sure that it won't be easily blown off.
Once all the preparations have been made, you can now plant the selected type of grass seed in the soil. Spread the seeds evenly and water the soil very lightly because too much water can wash away the grass seeds.
Make another round of sowing to ensure the bald spots left after water are covered. Lastly, you need to frequently check on it to remove the weeds that grow faster than the grass and cutting the grass only when it goes above three inches.
What Factors Do You Need to Consider Before Buying the Best Grass Seed for Sandy Soil?
1. Root Structure
The ability of the grasses to thrive in sandy soils has a lot to do with how the roots grow. Most of these grass types have a long, deep root system to find and catch moisture and nutrients that slip through the sand.
Longer roots will be able to get below the sandy top layer to get the moisture, and with the increased surface area, more nutrients can be absorbed. They help keep the grass in place despite the unstable environment given by sandy soils.
On the other hand, horizontal growing stolons and rhizomes will increase the stability further by creating thick mats. These mats are similar to more traditional sod types.
2. Drought Tolerance
Sandy soil is very porous and doesn't retain water well, which means that even if the land receives a lot of rainfall, plants growing in sandy soil may still experience a lack of water. For this reason, you want to choose grasses that are drought tolerant.
Such grasses can survive in less water, and their roots won't be easily damaged with the large pockets of air found in sandy soils. Most of these grasses are also able to come back to life even after long periods of dormancy because of extended drought.
When it comes to sandy soils, lack of water isn't always the problem because as the water moves through the substrates, it also pulls the nutrients. However, it means that plants growing in sandy soils will have fewer nutrients than those in less porous soils.
Hardy grass seeds can withstand long dry periods and thrive in environments where phosphorus, nitrogen, and other nutrients are quite scarce. Furthermore, they are less likely to be attacked by pests.
Additionally, choosing hardy grass will mean that you won't need pesticides to get rid of the nematodes and lawn-destroying bugs. This is because they can survive and keep your garden looking its best.
Frequently Asked Questions (FAQs) on Growing Grass in Sandy Soil Conditions
1. Will grass seed grow in sandy soil?
Definitely, with the best grass for sandy soil, lawns will thrive in porous and quick-draining conditions. However, following the right procedure is paramount to ensure the seeds will survive and the grass can grow the right way.
2. Can you put topsoil over the sand to grow grass?
For grass to thrive in sandy soil, you should avoid high organic matter soil mixes or heavy clay soil such as topsoil or garden soil mixes. This is because lawn grass won't reliably grow through more than two inches of fill. Moreover, a sandy fill, for example, pump sand or river sand, is preferred.
