How to Grow Parsley

Petroselinum crispum · Zones 5-9

Parsley is a biennial culinary herb, grown for the flavor it brings to the kitchen, ready to harvest about 75 days after planting. It's hardy across USDA zones 5 through 9, stands up to deer and grows just as well in a container as in the ground. Its summer flowers are a moderate draw for honeybees, native bees, and butterflies, 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 Parsley is

Parsley grows as a biennial and reaches around a foot and a half at maturity. It blooms yellow in summer. It's also deer-resistant and well suited to containers.

How to grow Parsley

Parsley grows in USDA zones 5 through 9 and is ready to harvest about 75 days after planting. Parsley does best in part sun — at least 4 hours of direct sun a day — and soil from pH 5.3 to 8.3, on well-drained ground. It needs around 1,100 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.

  1. Start the season right

    Plant parsley in part sun with at least 4 hours of direct sun. It grows in the cool halves of the year, so sow it in spring or late summer rather than waiting for midsummer heat.

  2. Match the soil

    Parsley prefers pH 5.3 to 8.3 (FAO ECOCROP). A quick soil test from your local Extension lab tells you whether to add lime or sulfur to land in band.

  3. Water steadily

    Keep the root zone evenly moist through establishment. A 2–3 inch mulch layer holds moisture without waterlogging.

  4. Harvest at maturity

    Parsley is ready about 75 days after planting (Cornell; PrairieMoon). Snip sprigs as you need them — regular cutting keeps the foliage tender and slows it bolting to flower.

Where Parsley thrives

Parsley is hardy across USDA zones 5 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 59 spans average winter lows from -20°F to 30°F (USDA PHZM 2023). Across the 50 states and DC, that band covers 25 outright and splits 25 more down the middle — and which side of that line your land sits on changes the answer.

Where Parsley stands, state by state

Parsley is rated for zones 59 — a cold floor USDA puts at -20 to -10°F. Across the 50 states and DC, 25 sit fully inside that band, the line runs through 25 more, and 1 sits outside it — and inside every split state, the same line runs on at county grain.

Winter cold is the limit here — the same plant often works in a container that comes under cover. Each link is that state’s own growing hub.

State zone extents: USDA Plant Hardiness Zone Map (PHZM) 2023. A zone is a 10°F band of average annual extreme minimum temperature, so a state that splits the band contains the boundary — its own page draws the county line, and a parcel report resolves which side your land sits on.

Before you harvest parsley, 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 parsley 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.

Frequently asked questions

Can I grow Parsley in my zone?

Parsley grows in USDA hardiness zones 5 through 9 (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 Parsley take to grow?

Parsley is ready to harvest about 75 days after planting (Cornell; PrairieMoon). Your local frost dates and soil temperature move that window earlier or later.

When should you plant Parsley?

Parsley is a cool-season crop, so it goes in during the cool halves of the year — early spring, and again in late summer for a fall planting — rather than at the height of summer heat. Your local frost dates set the exact window — a Growable Ground report reads them for your address.

How much sun does Parsley need?

Parsley 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 Parsley need?

Parsley prefers soil pH 5.3 to 8.3, on well-drained ground (FAO ECOCROP). Your report scores your parcel's actual soil against that using USDA SSURGO data.

Does Parsley attract pollinators?

Yes — parsley's flowers are a solid nectar source for honeybees, native bees, and butterflies. (Source: Pollinator Partnership.)

Is Parsley safe for pets?

Parsley is not known to be toxic to dogs or cats based on available data. Always supervise pets around new plantings. (Source: ASPCA.)
