Tomatillo is an annual grown for its fruit, ready to harvest about 60 days after planting. Season length, not a winter zone, decides where it grows. Notably, it stands up to deer. Its flowers are a modest draw for native bees, even though the fruit is the prize. As a nightshade, 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 Tomatillo is
Tomatillo grows as an annual and reaches around 3.5 feet at maturity. It's also deer-resistant.

How to grow Tomatillo
Season length, not a winter zone, decides where tomatillo grows; it is ready to harvest about 60 days after planting. Tomatillo does best in full sun — at least 6 hours of direct sun a day — and soil from pH 5 to 8, on well-drained ground. It needs around 2,300 growing degree days to mature and a growing season of at least 80 frost-free days, which is why climate matters as much as soil.

Start the season right
Plant tomatillo in full sun with at least 6 hours of direct sun, once the soil has warmed and frost risk has passed.
Match the soil
Tomatillo prefers pH 5 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. We haven't confirmed this against a published source yet. A 2–3 inch mulch layer holds moisture without waterlogging.
Harvest at maturity
Tomatillo is ready about 60 days after planting. We haven't confirmed this against a published source yet. Pick when the fruit is full-colored and parts easily from the stem.
Where Tomatillo thrives
Season length, not a winter zone, decides where tomatillo grows. 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 3–11 spans average winter lows from -40°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.

Where Tomatillo stands, state by state
Tomatillo is rated for zones 3–11 — a cold floor USDA puts at -40 to -30°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 tomatillo
In rotation planning, tomatillo counts as a Nightshade — beds recover best when nightshade crops don’t follow each other in the same spot year over year. (Growable Ground derivation — crop-rotation group from botanical family)

Good to know
One caution for pet owners — tomatillo is toxic to dogs and cats (mild severity). 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 tomatillo, 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 tomatillo 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.

How we know this about Tomatillo
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 Tomatillo in my zone?
Tomatillo is grown as an annual, so a hardiness zone does not decide it — its growing season follows your last and first frost dates. Soil pH, drainage, and frost dates on your specific parcel also shape whether it takes.
How long does Tomatillo take to grow?
Tomatillo is ready to harvest about 60 days after planting. We haven't confirmed this against a published source yet. Your local frost dates and soil temperature move that window earlier or later.
When should you plant Tomatillo?
Most growers plant tomatillo after the last spring frost, once the soil has warmed, leaving enough of the season for its 80-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 Tomatillo need?
Tomatillo 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 Tomatillo need?
Tomatillo prefers soil pH 5 to 8, on well-drained ground (FAO ECOCROP). Your report scores your parcel's mapped soil against that using USDA SSURGO data.
Does Tomatillo attract pollinators?
Yes — tomatillo's flowers are a modest nectar source for native bees. We haven't confirmed this against a published source yet.
Is Tomatillo safe for pets?
Tomatillo is toxic to dogs and cats with mild severity. 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.
