Cilantro is an annual culinary herb, grown for the flavor it brings to the kitchen, ready to harvest about 50 days after planting. It's hardy across USDA zones 2 through 11 and stands up to deer. Its summer flowers are a moderate draw for honeybees and native bees, even though the harvest is the prize. As a member of the carrot 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 Cilantro is
Cilantro grows as an annual and reaches around two feet at maturity. It blooms white in summer. It's also deer-resistant.
How to grow Cilantro
Cilantro grows in USDA zones 2 through 11 and is ready to harvest about 50 days after planting. Cilantro does best in part sun — at least 4 hours of direct sun a day — and soil from pH 4 to 8, on well-drained ground. It needs around 700 growing degree days to mature and a growing season of at least 35 frost-free days, which is why climate matters as much as soil.

Start the season right
Plant cilantro in part sun with at least 4 hours of direct sun, once the soil has warmed and frost risk has passed.
Match the soil
Cilantro prefers pH 4 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
Cilantro is ready about 50 days after planting (OSU-PNW; Johnny's). Snip sprigs as you need them — regular cutting keeps the foliage tender and slows it bolting to flower.
Where Cilantro thrives
On hardiness alone, cilantro 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 Cilantro stands, state by state
Cilantro 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 cilantro, 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 cilantro 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 Cilantro
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 Cilantro in my zone?
Cilantro 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 Cilantro take to grow?
Cilantro is ready to harvest about 50 days after planting (OSU-PNW; Johnny's). Your local frost dates and soil temperature move that window earlier or later.
When should you plant Cilantro?
Most growers plant cilantro after the last spring frost, once the soil has warmed, leaving enough of the season for its 35-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 Cilantro need?
Cilantro 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 Cilantro need?
Cilantro prefers soil pH 4 to 8, on well-drained ground (FAO ECOCROP). Your report scores your parcel's actual soil against that using USDA SSURGO data.
Does Cilantro attract pollinators?
Yes — cilantro's flowers are a solid nectar source for honeybees and native bees. (Source: Pollinator Partnership.)
Is Cilantro safe for pets?
Cilantro is not known to be toxic to dogs or cats based on available data. Always supervise pets around new plantings. (Source: ASPCA.)
