Starting your chili peppers from seeds during late winter to early spring ensures a bountiful harvest of spicy pods all summer long. But first, you need to decide which varieties to grow from the many options available.
If you crave intense heat, look for peppers with high Scoville Heat Units (SHU), which measure capsaicin levels—the compound responsible for the heat. For those who prefer a milder experience, there are sweet varieties for salsas, larger peppers ideal for stuffing, or options that add a gentle warmth to your meals without overwhelming heat. All of these varieties thrive in sunny locations.
Once you've made your selections, remember that these plants prefer warm climates, as indicated by their USDA hardiness rating of 11-12. The ideal temperature for seed germination is 82˚F. You can expect to see growth in about seven to 21 days. When seedlings reach about an inch tall, transfer them to individual pots filled with compost.
Young chili plants flourish in greenhouses, sunrooms, or bright windows where temperatures consistently remain above 70˚F. Some varieties can also be placed outside in sunny spots during the warmer months.
