What Washington, DC tomatillos need

SeedsThe cultivar decides the sauce. Everything downstream is damage control.
  • Toma Verde Tomatillo SeedMust have

    Salsa verde is not a green tomato sauce — it is a tomatillo sauce, and the difference is the tartness and the natural pectin that makes it cling. There is no substitute.

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.

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.

  • 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.

HarvestTiming, handling, and weighing what you actually got.
  • Garden Harvest Basket with Tool Caddy

    A harvest basket that doubles as a colander means the hose rinse happens in the garden, and the dirt stays outside. On a 20-pound tomato day that is a genuine time saving.

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.
