What Para Grass is
Para Grass reaches around five feet at maturity.
How to grow Para Grass
Para Grass grows in USDA zones 10 through 13. Para Grass does best in full sun — at least 6 hours of direct sun a day — and soil from pH 4.3 to 7.7, on consistently moist ground. It needs around 3,000 growing degree days to mature and a growing season of at least 120 frost-free days, which is why climate matters as much as soil.

Start the season right
Plant para grass in full sun with at least 6 hours of direct sun, once the soil has warmed and frost risk has passed.
Match the soil
Para Grass prefers pH 4.3 to 7.7 (USDA PLANTS Database). 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. Match watering to the plant's drainage preference and your local rainfall.
Turn it in before it seeds
Cut para grass 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.
Good to know
Good news for pet owners — para grass isn't known to be toxic to dogs or cats. (Source: ASPCA.)
Para Grass isn't classified as a notable pollinator plant in our data — pair it with high-value bloomers nearby to feed bees.
Where Para Grass thrives
Para Grass is hardy across USDA zones 10 through 13. Zone is only the starting point, though: the soil pH, drainage, and frost dates on your specific land decide how well it actually does.

Frequently Asked Questions
Can I grow Para Grass in my zone?
Para Grass grows in USDA hardiness zones 10 through 13 (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 Para Grass?
Most growers plant para grass after the last spring frost, once the soil has warmed, leaving enough of the season for its 120-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 Para Grass need?
Para Grass 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 Para Grass need?
Para Grass prefers soil pH 4.3 to 7.7, on consistently moist ground (USDA PLANTS Database). Your report scores your parcel's actual soil against that using USDA SSURGO data.
Does Para Grass attract pollinators?
Para Grass isn't classified as a notable pollinator plant in our data. Pairing it with high-value bloomers nearby keeps bees and butterflies fed.
Is Para Grass safe for pets?
Para Grass is not known to be toxic to dogs or cats based on available data (ASPCA). Always supervise pets around new plantings.
