Arugula is an annual grown for its leaves, ready to start cutting about 40 days after sowing. It's hardy across USDA zones 2 through 11, stands up to deer and grows just as well in a container as in the ground. As a brassica (the cabbage family), give it a fresh bed each year — away from where its relatives just grew — so the soil-borne pests and diseases of the family never get a foothold.

What Arugula is
Arugula grows as an annual and reaches around a foot at maturity. It's also deer-resistant and well suited to containers.
How to grow Arugula
Arugula grows in USDA zones 2 through 11 and is ready to harvest about 40 days after planting. Arugula does best in part sun — at least 4 hours of direct sun a day — and soil from pH 6 to 8.5, on well-drained ground. It needs around 700 growing degree days to mature and a growing season of at least 70 frost-free days, which is why climate matters as much as soil.

Start the season right
Plant arugula in part sun with at least 4 hours of direct sun, once the soil has warmed and frost risk has passed.
Match the soil
Arugula prefers pH 6 to 8.5 (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
Arugula is ready about 40 days after sowing (OSU-PNW; Johnny's). Cut the outer leaves as you need them — frequent harvest keeps new growth coming.
Where Arugula thrives
On hardiness alone, arugula 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 Arugula stands, state by state
Arugula 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.

Growing guides for arugula
In rotation planning, arugula counts as a Brassica — beds recover best when brassica crops don’t follow each other in the same spot year over year. (Growable Ground derivation — crop-rotation group from botanical family)

Before you harvest arugula, 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 arugula 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 Arugula
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 Arugula in my zone?
Arugula 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 Arugula take to grow?
Arugula is ready to harvest about 40 days after planting (OSU-PNW; Johnny's). Your local frost dates and soil temperature move that window earlier or later.
When should you plant Arugula?
Most growers plant arugula after the last spring frost, once the soil has warmed, leaving enough of the season for its 70-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 Arugula need?
Arugula does well in partial sun — around 4 hours of direct sun, and it takes some afternoon shade in stride. That flexibility makes it a good match for a bed the house or a nearby tree shades for part of the day. A Growable Ground report maps how the sun actually falls on your land, hour by hour, so you can set it where the light lines up.
What soil does Arugula need?
Arugula prefers soil pH 6 to 8.5, on well-drained ground (FAO ECOCROP). Your report scores your parcel's actual soil against that using USDA SSURGO data.
Is Arugula safe for pets?
Arugula is not known to be toxic to dogs or cats based on available data. Always supervise pets around new plantings. (Source: ASPCA.)
