Planting & Care

Start serrano seeds indoors 6–8 weeks before the last expected frost date. Sow seeds ¼ inch deep in a sterile seed-starting mix and keep the medium consistently moist at around 75–85°F (24–29°C) for best germination. Once seedlings have two sets of true leaves, transplant them into larger pots or harden them off gradually before moving outdoors after the danger of frost has passed.

Choose a sunny location with well-drained soil. Water regularly to keep the soil evenly moist, but avoid overhead watering to reduce disease risk. Mulch around plants to conserve moisture and suppress weeds. Fertilize lightly every few weeks with a balanced fertilizer. Harvest peppers when they reach full size and desired color—green for a tangy heat or red for a sweeter, more intense flavor.
