When to plant peppers in Louisiana
Start Jalapeño seeds indoors around Jan 3 and transplant around Mar 7 — the Louisiana statewide median, counted from a last spring frost of Feb 28 across 539 ZIP codes and 102 NOAA stations.
The rule: Eight weeks indoors on a heat mat (ten for habanero), then transplant one to two weeks after the last frost, once nights hold above 50 °F.
Louisiana peppers, by cultivar
Statewide median last frost Feb 28, first fall frost Nov 25, 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 |
|---|---|---|---|---|
| JalapeñoEarly Jalapeño (Capsicum annuum) | Jan 3 | Mar 7 | May 21 | 75 from transplant |
| CayenneLong Slim Cayenne (Capsicum annuum) | Jan 3 | Mar 7 | May 21 | 75 from transplant |

| HabaneroOrange Habanero (Capsicum chinense) | Dec 20 | Mar 14 | Jun 17 | 95 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 Louisiana's ZIP codes resolve to.

What these peppers become
What Louisiana peppers need
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.
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.
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.
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.
