What Muscadine Grape is
Muscadine Grape grows as a perennial and reaches around 30 feet at maturity. It blooms white in late spring.
How to grow Muscadine Grape
Muscadine Grape grows in USDA zones 7 through 9. Muscadine Grape does best in full sun — at least 6 hours of direct sun a day — and soil from pH 5.8 to 8, on well-drained ground. It needs around 3,000 growing degree days to mature and about 600 hours of winter chill to set fruit (Mississippi State University Extension P3067), which is why climate matters as much as soil.

Start the season right
Plant muscadine grape in full sun with at least 6 hours of direct sun, once the soil has warmed and frost risk has passed.
Match the soil
Muscadine Grape prefers pH 5.8 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.
Harvest at maturity
Pick when the fruit is full-colored and parts easily from the stem. Local Cooperative Extension guides publish timing tables.
Where Muscadine Grape thrives
Muscadine Grape is hardy across USDA zones 7 through 9. 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 7–9 spans average winter lows from 0°F to 30°F (USDA PHZM 2023). Across the 50 states and DC, that band covers 6 outright and splits 35 more down the middle — and which side of that line your land sits on changes the answer.

Where Muscadine Grape stands, state by state
Muscadine Grape is rated for zones 7–9 — a cold floor USDA puts at 0 to 10°F. Across the 50 states and DC, 6 sit fully inside that band, the line runs through 35 more, and 10 sit outside it — and inside every split state, the same line runs on at county grain.

Good to know
One caution for pet owners — muscadine grape is toxic to dogs (severe severity). Keep it out of reach, and call ASPCA Animal Poison Control at (888) 426-4435 in an emergency. (Source: ASPCA.)
Muscadine Grape isn't classified as a notable pollinator plant in our data — pair it with high-value bloomers nearby to feed bees.
Before you harvest muscadine grape, know your soil
Anything you grow to eat takes up what's in the ground it grows in, so it's worth knowing what's documented near you before you plant muscadine grape for food. Our free screen reads 8 federal source types across roughly 1.8M indexed sites and shows which sit near your address and which way they drain. It's a screening estimate from public records and proximity — not a soil test — so a nearby record means a soil test is worth it, not that your soil is unsafe.

How we know this about Muscadine Grape
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 Muscadine Grape in my zone?
Muscadine Grape grows in USDA hardiness zones 7 through 9. Zone is one factor — soil pH, drainage, and frost dates on your specific parcel also shape whether it takes.
When should you plant Muscadine Grape?
Most growers plant muscadine grape after the last spring frost, once the soil has warmed. Your local frost dates set the exact window — a Growable Ground report reads them for your address.
How much sun does Muscadine Grape need?
Muscadine Grape 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 Muscadine Grape need?
Muscadine Grape prefers soil pH 5.8 to 8, on well-drained ground (FAO ECOCROP). Your report scores your parcel's actual soil against that using USDA SSURGO data.
Does Muscadine Grape attract pollinators?
Muscadine Grape isn't classified as a notable pollinator plant in our data. Pairing it with high-value bloomers nearby keeps bees and butterflies fed.
Is Muscadine Grape safe for pets?
Muscadine Grape is toxic to dogs with severe severity. Keep it out of reach, and call ASPCA Animal Poison Control at (888) 426-4435 in an emergency. (Source: ASPCA.)
