Sandy soil is a real treat! We have it, and it offers the best drainage of anywhere I've ever lived. This loose, gritty soil shows up in coastal areas, dry climates, and new builds; I'm in Rochester, NY, but not close enough to Lake Ontario to consider myself lakefront. Even lake-adjacent soil can be sandy. But not all grass thrives in our soil.
We've learned over the years that it takes extra consideration, and more than a little extra care to help it root and thrive with foot traffic. So, let’s break down what works, what doesn’t, and what actually grows.
What makes sandy soil different when it comes to lawn care?
Sandy soil has large particles that don’t hold water or nutrients very well. It drains fast, which helps prevent soggy roots, but it also dries out quickly. For grass, that means more frequent watering and a little help holding onto nutrients.
Here’s what sandy soil typically looks like:
- Low water retention/dries out fast after rain or watering
- Feels gritty or coarse in your hand
- Lacks organic matter
- Struggles to hold nutrients
Because of this, some grasses struggle to grow. The grass roots dry out, and the grass blades turn brown. But other types—especially those with deep roots or drought tolerance—can thrive if given the right start.
Best Grass Types for Sandy Soil Conditions
So, can you grow grass in sand? Yes, with the right grass seed. Some grasses are built to handle these soil conditions. Look for types that send roots deep into the soil and don't mind quick drainage.
Here are a few good choices:
- Bermuda grass – Common on sports fields, this grass loves full sun and grows fast in sandy soil. It spreads quickly and stands up to heat.
- Bahia grass – Known for handling poor soil and heat, this is great for low-maintenance lawns in southern areas.
- Zoysia grass – Dense, drought-tolerant, and slow-growing. It handles sandy soil well and offers a soft feel underfoot.
- Centipede grass – A slow grower that’s good for sandy soil and needs less mowing. It works best in warm climates.
- Tall fescue grasses – This cool-season grass has a deep root system and tolerates a range of soil conditions, including sandy patches.
- Creeping red fescue – Good for shady or cooler areas. It’s not as drought-tolerant, but it does better than most in sandy spots with some care.
You’ll find seed mixes that blend two or more of these, the seed bags are often labeled “grass seed for sandy soil.” These mixes improve coverage and help the lawn adjust to changing light, foot traffic, and moisture levels.
How to Help Grass Grow in Sand
Even the best grass needs a little help when it’s planted in sandy soil. You don’t need to change your whole yard, but you should take a few easy steps to set it up for success.
- Add organic matter like compost or peat moss to hold water and nutrients
- Use a starter fertilizer when seeding
- Choose grass seeds suited for your climate and sunlight
- Water more often, but not too much—light, frequent watering helps
- Aerate the lawn once a year to help roots grow deeper
- Use mulch clippings or topdress with compost each season
If your lawn struggles, a soil test can tell you exactly what’s missing. Sandy soil may need extra nutrients like nitrogen or potassium, which you can add through organic fertilizer.
FAQ
Can grass grow in pure sand without any soil added?
It can, but it’s tricky. Most grasses won’t survive in pure sand unless you water constantly and feed it regularly. Adding a thin layer of organic material, like compost or topsoil on top can make a big difference, even if you don't replace the whole yard.
Is sandy soil better for some lawns than others?
Yes. Sandy soil works well in warm, sunny climates where grasses like Bermuda grass or Bahia thrive. It's also a plus if you want quick drainage or live in a place with heavy rain. That said, it’s not great for shady spots or lawns with high foot traffic, since it doesn’t hold water or nutrients well.
