When to plant tomatoes in Georgia
Start Roma Tomato seeds indoors around Feb 9 and transplant around Mar 30 — the Georgia statewide median, counted from a last spring frost of Mar 23 across 751 ZIP codes and 130 NOAA stations.
The rule: Six weeks indoors at 75–85 °F soil, then transplant a week after the last frost and cage at transplant.
Georgia tomatoes, by cultivar
Statewide median last frost Mar 23, first fall frost Nov 11, 2027 season. Each cultivar's own indoor lead time and days to maturity, same engine as the Plan Builder.
| Cultivar | Start indoors | Plant out | First harvest | Days |
|---|---|---|---|---|
| Roma TomatoRoma VF (determinate paste) | Feb 9 | Mar 30 | Jun 13 | 75 from transplant |
| San Marzano TomatoSan Marzano (indeterminate paste) | Feb 9 | Mar 30 | Jun 18 | 80 from transplant |
Tight means first harvest lands within two weeks of the median first fall frost. Statewide dates are the ZIP-weighted median of every NOAA 1991–2020 station Georgia's ZIP codes resolve to.

What Georgia tomatoes need
Roma Tomato Seed (300+)
The determinate paste tomato: it ripens most of its crop inside a three-week window. That is a liability for eating and an enormous advantage for sauce day.
San Marzano Tomato SeedMust have
The paste tomato Italian canners actually use. Low seed cavity, low water, high pectin: it reduces to a sauce in half the time a slicer takes and never tastes thin.
Organic Seed Starter Potting MixMust have
Seed-starting mix is not potting soil with a nicer label — it is finer, lighter, and low in nutrients on purpose, because a seedling's first roots want air and moisture, not fertiliser.
Seedling Heat Mat + Digital ThermostatMust have
Peppers germinate on soil temperature, not air temperature. At 65 °F a habanero takes a month and half of them rot; at 85 °F it is up in eight days. The thermostat is the half that matters.
T8 Full-Spectrum Grow Lights, 1 ft 4-packMust have
A south window in March delivers a fraction of the light a pepper seedling needs, and the plant tells you by stretching. Two inches of LED above the canopy for 16 hours a day fixes it permanently.
72-Cell Trays with 1020 Bottoms, 5-PackMust have
The cheap black nursery trays crack after one season and flex enough to break roots when you lift them. These do not. Over five seasons the price per use is lower than the throwaways.
5-Gallon Fabric Grow Bags, 5-Pack
Fabric pots air-prune roots and drain faster than a plastic pot can, which is the entire reason container tomatoes fail. Five gallons is the honest minimum for a pepper; a tomato wants ten.
Ocean Forest Potting SoilMust have
Pre-charged with enough nutrition to carry a transplant for its first month without feeding, which is exactly the window when most container plants stall.
Organic Tomato-Tone 3-4-6 with 8% CalciumMust have
The NPK ratio is the point: low nitrogen, higher potassium. Feed a tomato a high-nitrogen lawn fertiliser and you get a magnificent six-foot plant with four tomatoes on it.
Rot-Stop Blossom End Rot Concentrate
Blossom end rot is almost never a soil calcium shortage — it is a calcium *transport* failure caused by inconsistent water. A foliar calcium spray buys time while you fix the watering, which is the real cure.
58" Square Tomato Cages, 3-PackMust have
The conical wire tomato ring from the hardware store is 33 inches tall and an indeterminate San Marzano will laugh at it in July. Height and square geometry are what actually hold a loaded plant.
Drip Irrigation System with Timer, 16 Nozzles
Blossom end rot, split tomatoes and bitter fruit all trace back to the same thing: water that swings. A $50 timer removes the human from the loop and removes the swing.
Captain Jack Copper Fungicide, 16 oz
Early blight and septoria arrive with a wet July and work up the plant from the bottom. Copper is preventative — sprayed after you see it, you are already losing.
Thuricide BT Concentrate, 16 oz
Bacillus thuringiensis kills caterpillars and nothing else. For tomato hornworms — which can strip a plant in 48 hours — it is the most targeted tool that exists.
Stainless Steel Food Mill, 3 discsMust have
A blender pulverises tomato skins and seeds into the sauce, which is where bitterness comes from. A mill separates them out — no blanching, no peeling, no ice bath. It removes an entire hour from sauce day.
