Jalapeno is a medium-heat chili pepper prized for its distinctive smoky flavor and versatility in the kitchen. It's used fresh, smoked (as chipotles), pickled, or cooked into salsas and other dishes. Gardeners grow it for reliable yields and the satisfaction of harvesting homegrown peppers that far outpace supermarket quality.

Sow seed in flats, 4 seeds/in., 1/4" deep, in late March or about 8 weeks prior to transplanting. Maintain soil temperatures at 80-90F. When first true leaves appear, transplant into 2" cell containers.

Jalapenos need full sun (6–8 hours daily), warm soil, and consistent warmth to thrive. Water deeply when the top inch of soil dries out; avoid letting plants dry out completely or sit in waterlogged soil, as both stress the plant and reduce yields. Fertilize every 3–4 weeks with a balanced or slightly phosphorus-rich fertilizer once flowering begins. Staking or caging is helpful to support the weight of fruit. Watch for aphids, spider mites, and powdery mildew in humid conditions; spray with insecticidal soap or neem oil at first sign. Blossom end rot (dark sunken spots) indicates inconsistent watering or low calcium; mulch well and water evenly to prevent it.

Jalapenos can be harvested green (60–70 days after transplanting) for a fresher, slightly grassy bite, or left to fully ripen red (85–90 days) for sweeter, hotter peppers. Snip peppers with pruners rather than pulling to avoid damaging the plant; regular harvesting encourages more fruit production. Store fresh peppers in a paper bag in the crisper drawer for up to 2 weeks, or slice and freeze them for longer storage.
