Planting & Care

Start Serrano pepper seeds indoors 6-8 weeks before the last frost date. Sow seeds 1/4 inch deep in seed-starting mix and keep the soil warm (75-85°F) and consistently moist. Germination typically occurs in 7-14 days. Once seedlings have two sets of true leaves, transplant them into larger pots or harden them off for the garden after the danger of frost has passed.

Provide full sun and well-drained soil. Water regularly, allowing the top inch of soil to dry out between waterings. Mulch to retain moisture and suppress weeds. Fertilize lightly when plants begin to flower. Harvest peppers when they reach desired size and color; regular harvesting encourages more fruit production.
