Match the soil
Pull a soil test from your local Extension lab to confirm pH and drainage match french tarragon's needs before planting.
Harvest at maturity
Snip sprigs as you need them — regular cutting keeps the foliage tender and slows it bolting to flower. Local Cooperative Extension guides publish timing tables.
Where French Tarragon thrives
French Tarragon is hardy across USDA zones 3 through 7. 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 3–7 spans average winter lows from -40°F to 10°F (USDA PHZM 2023). Across the 50 states and DC, that band covers 23 outright and splits 25 more down the middle — and which side of that line your land sits on changes the answer.

Where French Tarragon stands, state by state
French Tarragon is rated for zones 3–7 — a cold floor USDA puts at -40 to -30°F. Across the 50 states and DC, 23 sit fully inside that band, the line runs through 25 more, and 3 sit outside it — and inside every split state, the same line runs on at county grain.

French Tarragon’s band covers part of each of these states — which side of the line your county sits on changes the answer, and each state page draws it.
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.

Good to know
One caution for pet owners — french tarragon is toxic to dogs, cats and horses. Keep it out of reach, and call ASPCA Animal Poison Control at (888) 426-4435 in an emergency. We haven't confirmed this against a published source yet.

Before you harvest french tarragon, 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 french tarragon for food. Our free screen reads 8 federal source types across roughly 950K 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.
