How to Grow Tomato

Solanum lycopersicum · Zones 2-11

Tomato is an annual grown for its fruit, ready to harvest about 75 days after planting. It's hardy across USDA zones 2 through 11 and grows just as well in a container as in the ground. Its summer flowers are a moderate 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 Tomato is

Tomato grows as an annual and reaches around six feet at maturity. It blooms yellow in summer. It's also well suited to containers.

How to grow Tomato

Tomato grows in USDA zones 2 through 11 and is ready to harvest about 75 days after planting. Tomato does best in full sun — at least 6 hours of direct sun a day — and soil from pH 5 to 7.5, on well-drained ground. It needs around 2,200 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 tomato in full sun with at least 6 hours of direct sun, once the soil has warmed and frost risk has passed.

  2. Match the soil

    Tomato prefers pH 5 to 7.5 (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

    Tomato is ready about 75 days after planting (OSU-PNW; Cornell). Pick when the fruit is full-colored and parts easily from the stem.

Where Tomato thrives

On hardiness alone, tomato 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 211 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 Tomato stands, state by state

Tomato is rated for zones 211 — 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.

Tomato’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 — tomato 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. (Source: ASPCA.)

Before you harvest tomato, 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 tomato 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.

Your land is one point inside Tomato's range

This page resolves to the species. Your state page draws the county line, and a report reads the parcel — the soil pH, drainage, sun, and frost dates on your exact ground, which no species average can see.

How we know this about Tomato

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 Tomato in my zone?

Tomato 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 Tomato take to grow?

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

When should you plant Tomato?

Most growers plant tomato 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 Tomato need?

Tomato 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 Tomato need?

Tomato prefers soil pH 5 to 7.5, on well-drained ground (FAO ECOCROP). Your report scores your parcel's actual soil against that using USDA SSURGO data.

Does Tomato attract pollinators?

Yes — tomato's flowers are a solid nectar source for native bees. (Source: Xerces Society.)

Is Tomato safe for pets?

Tomato is toxic to pets (dogs,cats) with mild severity. Keep it out of reach, and call ASPCA Animal Poison Control at (888) 426-4435 in an emergency. (Source: ASPCA.)
