What Georgia tomatoes need

SeedsThe cultivar decides the sauce. Everything downstream is damage control.
  • 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.

StartSoil temperature and light intensity, indoors, weeks before your frost date.
  • 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.

GrowRoot volume, nutrition and structure. Where most home crops actually fail.
  • 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.

ProtectFrost, hornworms, aphids, and the fungal pressure that follows a wet July.
  • 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.

CookReduction, texture, and the non-reactive pans that keep tomato tasting like tomato.
  • 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.
