Tomato in Zone 7a & 7b
Solanum lycopersicum
Yes, tomato grows in zones 7a and 7b. Start seeds indoors Feb 27–Mar 6 and plant out Apr 24–May 1.
When to plant tomato in zone 7b
Zones 7a and 7b share the same average frost dates, so this page covers both.
Method: Start indoors: Start indoors from seed, then transplant outside. It 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.
Plant alongside it in zone 7b
These go outside within two weeks of tomato in zone 7b, so one planting day can cover them.

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.

Varieties we recommend, and where to get them:
- Iron Lady: Carries the Ph2 + Ph3 resistance genes for strong resistance to late blight plus early blight and Septoria leaf spot, worth considering in disease-prone, humid climates. Buy: High Mowing Organic Seeds Full notes
- Sweet 100 (Super Sweet 100): Mississippi State University Extension's Southern Gardening series lists Super Sweet 100 among the earliest tomatoes, ripening in as few as 50 days from transplant, a prolific cherry type useful where you want fruit before summer heat stalls set. Buy: Burpee Full notes
- 'Cherokee Purple' (best for heirloom flavor): Bonnie Plants lists 10-12 ounce fruit with dusky pink skin and deep red interior, 80-90 days, and vigorous indeterminate vines needing strong staking. Buy: Botanical Interests · True Leaf Market · Burpee · High Mowing Organic Seeds Full notes
- 'San Marzano' (best for sauce and canning): An Italian paste type, 70-90 days, oblong 3-4 inch fruit with thick flesh and few seeds, bred to cook down into sauce rather than eaten fresh like the beefsteak varieties above. Buy: Botanical Interests · Burpee Full notes
- 'Celebrity' (F1) (best for broad disease resistance): Cornell's disease-resistant variety guide lists Celebrity with resistance to Fusarium wilt, Verticillium wilt, tobacco and tomato mosaic virus, root-knot nematode, gray leaf spot and Alternaria stem canker, a broader resistance package than any single variety above.
