Pepper (Jalapeno)

Jalapeno is the standard, widely open-pollinated hot pepper in Decatur's Zone 8a, following the same slow-start, warm-season arc as sweet peppers, prone to attractive corking as it sizes up, and useful both fresh at the green stage and smoked-and-dried into chipotle once fully red.

1. 1

   Seedling

   Weeks 1-8 after sowing, started indoors mid-to-late January for transplant after last frost (~Mar 28)

   You'll see Oval cotyledons first, then pointed true leaves; growth is slow and steady, and a healthy seedling stays compact and deep green.

   Do Keep soil warm (75-85F, a heat mat speeds and evens germination) and give strong, close light right away to prevent stretching.

2. 2

   Transplant

   Late March through mid-April, once nighttime lows hold above 55F and soil has warmed

   You'll see A ready transplant has 4-6 true leaves and a sturdy stem, ideally no flower buds yet.

   Do Harden off over 5-7 days, transplant into warm soil, and stake or cage this upright, heavy-fruiting plant early.

3. 3

   Establishing / early branching

   First 2-3 weeks after transplant

   You'll see Resumed leaf growth, new side branches forming, and the first flower buds appearing at the growing tip.

   Do Top or pinch the plant once and remove the first flower bud(s) to push branching before letting it fruit freely.

4. 4

   Flowering and fruit set

   Late May through September

   You'll see Small white, star-shaped flowers open along the branches and swell into tiny green peppers within days of pollination.

   Do Keep watering consistent through fruit set; once plants are established, easing water back slightly on purpose later can help build a bit more heat.

5. 5

   Corking and ripening

   Roughly 60-75 days from transplant to first mature-size green fruit; full color change to red takes another 2-4+ weeks

   You'll see Watch for corking: light tan to brown, cork-like streaks or striations on the skin, caused by rapid growth splitting the surface as the fruit sizes up; fruit then shifts from green to red as it fully ripens.

   Do Treat corking as a good sign of flavor and near-ripeness rather than a defect, and decide per-fruit whether to pick green or let it fully color red.

6. 6

   Harvest and drying

   Ongoing through the season, with a final push before first frost (~Nov 12)

   You'll see Firm, glossy fruit at your target size and color is ready; jalapeno's thicker wall makes it slower to air-dry than a thin-fleshed pepper.

   Do Pick with scissors or pruners, and route extra fruit toward a dehydrator or smoking-then-drying rather than plain air drying.

7. 7

   Seed saving

   From fully mature (red, color-ripened), overripe fruit at the end of the season

   You'll see Seeds are pale tan, flat, and firm inside a fully ripe red fruit; seed from green fruit is underdeveloped and won't germinate well.

   Do Isolate from other pepper varieties before flowering if true seed matters, then harvest seed from a fully ripe fruit and dry it thoroughly before storing.
