📖 About This Plant

Pepper (Jalapeño) is the world's most recognizable hot pepper, a Mexican staple with a medium heat level (2,500–8,000 Scoville heat units) that delivers satisfying kick without overwhelming the palate. Named after the city of Xalapa in Veracruz, Mexico, the jalapeño's dark-green fruits average 2–4 inches in length and have a distinctive thick, crisp wall that makes them ideal for stuffing, roasting, pickling, and fresh slicing. As the fruits mature, they slowly turn red and develop an earthier, somewhat sweeter flavor — red jalapeños are excellent for making chipotles when smoked and dried. A single well-tended plant in a warm climate can produce 25–35 fruits over a season, making jalapeños one of the highest-value hot peppers for the home garden.

🌱 Care Tips

Start jalapeño seeds indoors 8–10 weeks before your last frost date — peppers are slow germinators and need warmth (70–85°F) to sprout reliably; a heat mat under the seed tray dramatically improves germination speed and percentage. Transplant outdoors only after nighttime temperatures are consistently above 55°F, as cold soil stunts pepper growth and can cause them to drop flowers before setting fruit. Space plants 14–18 inches apart in full sun with fertile, well-drained soil enriched with compost. Water deeply once or twice per week rather than lightly every day; deeper watering encourages deeper rooting and stronger plants. Apply a low-nitrogen, high-potassium fertilizer once flowers appear — too much nitrogen produces lush foliage but few fruits. Jalapeños respond well to calcium supplementation (crushed eggshells or gypsum worked into the soil) to prevent blossom end rot. Harvest fruits while still dark green for classic jalapeño flavor, or leave to ripen red for sweeter, earthier heat. Corking — white stretch marks on the skin — is normal and actually indicates mature, flavorful fruits.
