Tomato in Zone 7a & 7b
Solanum lycopersicum
When to plant tomato in zone 7b
Zones 7a and 7b share the same average frost dates in our data, so this page covers both.
Method: Start indoors: Start indoors from seed, then transplant outside. Tomato needs a head start most zones can't give it by direct-sowing alone.
| Start indoors | Feb 27–Mar 6 |
|---|---|
| Direct sow / transplant outside | Apr 24–May 1 |
| Estimated harvest | Jul 3–Jul 10 (~70 days after transplanting) |
Spacing: 1 per square foot (square-foot-gardening spacing). Mature height: 3-6 ft.
Tomatoes are the crop most people plant first, and for good reason: a single well-tended plant can produce for months, and the taste difference between a homegrown and store-bought tomato is the single biggest "why do I garden" argument there is.
How tomato fits zone 7's season
Zone 7b's frost-free window runs about 198 days, from April 10 to October 25. Tomato needs about 70 days from transplant to first harvest.
Good companions
- Basil: Widely reputed to improve tomato flavor and repel pests, but a multi-year, garden-scale controlled trial found no consistent taste preference in blind tests, and no evidence basil reduced pest pressure — treat this as one of companion planting's least-supported popular claims.
- Marigold: UF/IFAS Extension confirms French marigold is effective against a wide range of root-knot nematode species — a real, documented effect, not folklore. The insect-pest-deterrent half of this claim is less well documented.
- Carrot: Loosens soil for tomato roots without competing for space above ground.
