Oregon peppers, by cultivar

Statewide median last frost Apr 11, first fall frost Oct 30, 2027 season. Each cultivar's own indoor lead time and days to maturity, same engine as the Plan Builder.

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 Oregon's ZIP codes resolve to; 30 of 428 ZIPs have no datable freeze and are left out.

What Oregon peppers need

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

    The one you smoke into chipotle. Left on the plant to red and corked, then cold-smoked, a jalapeño stops being a taco garnish and becomes the backbone of an adobo.

  • Organic Cayenne (Long Slim) Seed

    The long, thin, wall-thin cayenne that dries in a week and grinds to a clean red powder. If you want flakes and powder as well as sauce, this is the plant that does both.

  • Serrano Pepper Seed

    Cleaner and greener than a jalapeño at roughly three times the heat. The correct chile for salsa verde and zhoug, where you want brightness rather than smoke.

  • Marconi Red Sweet Pepper Seed

    A long Italian sweet pepper that roasts and peels far better than a bell. Romesco and any red-pepper paste wants this, not a supermarket bell.

  • Habanero Orange Pepper SeedMust have

    The workhorse superhot for sauce: 100,000–350,000 SHU with a genuine apricot-floral top note that survives fermentation. Nothing else in this range tastes like fruit instead of pure burn.

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.

HarvestTiming, handling, and weighing what you actually got.
  • 6" Micro-Tip Pruning SnipsMust have

    Ninety percent of sauce-garden cutting is snipping a pepper stem or a basil node, and a fine-tipped snip does it better than any pruner. Pulling peppers by hand tears the branch.

  • Nitrile Exam Gloves, 200 pcs, food-safeMust have

    Capsaicin is oil-soluble and does not wash off with soap. Seeding a pound of habaneros bare-handed means eight hours of burning hands and one unforgettable mistake involving your own eye.

CookReduction, texture, and the non-reactive pans that keep tomato tasting like tomato.
  • Pellet Smoker Tube, 12", Set of 2

    Chipotle is nothing but a red jalapeño that has been cold-smoked for hours. A pellet tube turns any covered grill into a cold smoker for eighteen dollars.

  • Food Dehydrator, 6 Stainless Trays

    Sun-drying chiles works in Oaxaca and fails in Ohio — humidity lets mould win the race. Controlled 125 °F airflow dries a full cayenne harvest overnight, every time.

  • One-Touch Coffee & Spice Grinder

    Dried cayenne into powder in fifteen seconds. Dedicate one to chiles — grind coffee in it afterwards and you will find out exactly how well capsaicin sticks to plastic.
