Snap Bean is an annual grown for its pods, ready to pick about 55 days after sowing. It's hardy across USDA zones 2 through 11. Its summer flowers are a moderate draw for honeybees and native bees, even though the pods are the prize. A nitrogen-fixer, it draws nitrogen from the air and feeds it back to the soil — turn it under or leave the roots in place, and the next planting inherits a richer bed.

What Snap Bean is
Snap Bean grows as an annual and reaches around two feet at maturity. It blooms white in summer.
How to grow Snap Bean
Snap Bean grows in USDA zones 2 through 11 and is ready to harvest about 55 days after planting. Snap Bean does best in full sun — at least 6 hours of direct sun a day — and soil from pH 4 to 9, on well-drained ground. It needs around 1,200 growing degree days to mature and a growing season of at least 50 frost-free days, which is why climate matters as much as soil.

Start the season right
Plant snap bean in full sun with at least 6 hours of direct sun, once the soil has warmed and frost risk has passed.
Match the soil
Snap Bean prefers pH 4 to 9 (FAO ECOCROP). A quick soil test from your local Extension lab tells you whether to add lime or sulfur to land in band. It fixes its own nitrogen, so skip the high-nitrogen feed and instead dust the seed with a matching rhizobium inoculant at sowing.
Water steadily
Keep the root zone evenly moist through establishment. A 2–3 inch mulch layer holds moisture without waterlogging.
Harvest at maturity
Snap Bean is ready about 55 days after sowing (OSU-PNW; Johnny's). Pick the pods young and tender, before the seeds inside fully swell.
Where Snap Bean thrives
On hardiness alone, snap bean grows across most of the country — its range (USDA zones 2 through 11) is unusually wide. 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 2–11 spans average winter lows from -50°F to 50°F (USDA PHZM 2023). Across the 50 states and DC, that band covers 48 outright and splits 3 more down the middle — and which side of that line your land sits on changes the answer.

Where Snap Bean stands, state by state
Snap Bean is rated for zones 2–11 — a cold floor USDA puts at -50 to -40°F. Across the 50 states and DC, 48 sit fully inside that band, the line runs through 3 more, and 0 sit outside it — and inside every split state, the same line runs on at county grain.

Before you harvest snap bean, 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 snap bean for food. Our free screen reads 9 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 Snap Bean
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 Snap Bean in my zone?
Snap Bean grows in USDA hardiness zones 2 through 11 (USDA PHZM 2023). Zone is one factor — soil pH, drainage, and frost dates on your specific parcel also shape whether it takes.
How long does Snap Bean take to grow?
Snap Bean is ready to harvest about 55 days after planting (OSU-PNW; Johnny's). Your local frost dates and soil temperature move that window earlier or later.
When should you plant Snap Bean?
Most growers plant snap bean after the last spring frost, once the soil has warmed, leaving enough of the season for its 50-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 Snap Bean need?
Snap Bean 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 Snap Bean need?
Snap Bean prefers soil pH 4 to 9, on well-drained ground (FAO ECOCROP). Your report scores your parcel's actual soil against that using USDA SSURGO data.
Does Snap Bean attract pollinators?
Yes — snap bean's flowers are a solid nectar source for honeybees and native bees.
Is Snap Bean safe for pets?
Snap Bean is not known to be toxic to dogs or cats based on available data. Always supervise pets around new plantings. (Source: ASPCA.)
