Tomato in Zone 11a & 11b
Solanum lycopersicum
Yes, tomato grows in zones 11a and 11b. Start seeds indoors in Jun–Dec and plant out in Aug–Feb.
When to plant tomato in zone 11b
Zones 11a and 11b 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.
| Window | Summer window |
|---|---|
| Start indoors | Jun–Dec |
| Direct sow / transplant outside | Aug–Feb |
| Estimated harvest | ~70 days after transplanting |
Spacing: 1 per square foot (square-foot-gardening spacing). Mature height: 3-6 ft.

Before you plant: Zone 11b summers commonly stall tomato's fruit set midseason. See the details below.

These go outside within two weeks of tomato in zone 11b, 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 11's season
Zone 11b is frost-free, so frost is not what limits the calendar here. What you can plant, and when, comes down to summer heat and daylength instead.
Heat warning for zone 11b: Zone 11b summer nights commonly exceed 75°F, which stalls pollination and causes blossom drop in Tomato at the height of summer (University of Maryland Extension, via UDel Cooperative Extension). Expect a slow patch for fruit set during the hottest stretch even though the plant keeps growing. It typically resumes once nights cool.
Tomato planting windows in every zone
Zone 11b is highlighted. Useful for comparing against a neighbouring zone, or for a garden somewhere else.

| 10a & 10bSpring window | Dec–Feb | Feb–Apr | ~70 days after transplanting |
| Summer window | May–Jul | Jul–Sep | ~70 days after transplanting |
| 11a & 11bSummer window (your zone) | Jun–Dec | Aug–Feb | ~70 days after transplanting |
Harvest dates are about 70 days after the sow or plant-out date, not after starting seeds indoors.
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. (usually zones 2-10, so not a pairing for zone 11b)
Where to buy tomato seeds
Botanical Interests · True Leaf Market · Burpee · High Mowing Organic Seeds (each supplier's tomato seeds)
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.
