Zoysiagrass is a cover crop — grown to build and protect the soil rather than for a harvest of its own. It's hardy across USDA zones 5 through 10, shrugs off deer and shrugs off dry spells.

What Zoysiagrass is
Zoysiagrass grows as a perennial and reaches around a foot at maturity. It blooms yellow in summer. It's also deer-resistant.
How to grow Zoysiagrass
Zoysiagrass grows in USDA zones 5 through 10. Zoysiagrass does best in full sun — at least 6 hours of direct sun a day — and soil from pH 5 to 8, on well-drained to fast-draining ground. It needs a growing season of at least 150 frost-free days, which is why climate matters as much as soil.

Start the season right
Plant zoysiagrass in full sun with at least 6 hours of direct sun, once the soil has warmed and frost risk has passed.
Match the soil
Zoysiagrass prefers pH 5 to 8 (FAO ECOCROP). A quick soil test from your local Extension lab tells you whether to add lime or sulfur to land in band.
Water steadily
Keep the root zone evenly moist through establishment. A 2–3 inch mulch layer holds moisture without waterlogging.
Turn it in before it seeds
Cut zoysiagrass down or turn it into the soil before it sets seed, while the growth is still green — that's when it returns the most to the ground.
Where Zoysiagrass thrives
Zoysiagrass is hardy across USDA zones 5 through 10. Zone is only the starting point, though: the soil pH, drainage, and frost dates on your specific land decide how well it actually does.
A USDA zone is a 10°F band of average annual extreme winter minimum, so zones 5–10 spans average winter lows from -20°F to 40°F (USDA PHZM 2023). Across the 50 states and DC, that band covers 29 outright and splits 21 more down the middle — and which side of that line your land sits on changes the answer.

Where Zoysiagrass stands, state by state
Zoysiagrass is rated for zones 5–10 — a cold floor USDA puts at -20 to -10°F. Across the 50 states and DC, 29 sit fully inside that band, the line runs through 21 more, and 1 sits outside it — and inside every split state, the same line runs on at county grain.

How we know this about Zoysiagrass
The figures above are cited per row, not per site: the pH band names this plant’s own source column, the three temperature figures each carry their own, and days-to-maturity cites the publication that actually lists it. All of it comes from the Growable Ground Plant Database — a compilation over FAO ECOCROP, USDA PLANTS, and university Extension sources, published openly with per-field provenance.

Frequently asked questions
Can I grow Zoysiagrass in my zone?
Zoysiagrass grows in USDA hardiness zones 5 through 10 (USDA PHZM 2023). Zone is one factor — soil pH, drainage, and frost dates on your specific parcel also shape whether it takes.
When should you plant Zoysiagrass?
Most growers plant zoysiagrass after the last spring frost, once the soil has warmed, leaving enough of the season for its 150-day frost-free need. Your local frost dates set the exact window — a Growable Ground report reads them for your address.
How much sun does Zoysiagrass need?
Zoysiagrass needs full sun — a spot that catches at least 6 hours of direct summer sun a day. In more shade it still grows, but usually gives a smaller, later crop. The catch is that a yard rarely gets even light everywhere — a fence, the house, or one tall tree can quietly take those hours. A Growable Ground report reads the real sun-hours across your land, canopy and buildings included, so you can pick the brightest bed before you plant.
What soil does Zoysiagrass need?
Zoysiagrass prefers soil pH 5 to 8, on well-drained to fast-draining ground (FAO ECOCROP). Your report scores your parcel's actual soil against that using USDA SSURGO data.
Does Zoysiagrass attract pollinators?
Zoysiagrass isn't classified as a notable pollinator plant in our data. Pairing it with high-value bloomers nearby keeps bees and butterflies fed.
Is Zoysiagrass safe for pets?
Zoysiagrass is not known to be toxic to dogs or cats based on available data. Always supervise pets around new plantings. (Source: ASPCA.)
