🌾 Sow directly in the garden — Carolina Reaper is not usually started indoors.
Do not transplant seedlings outdoors until all risk of frost has passed and soil temperatures are warm enough for this sensitive warm-season crop.
Soil, care & harvest
Prepare well-draining soil with a pH between 6.0 and 7.0. As a warm-season crop, start seeds indoors only after all danger of frost has passed or when night temperatures are consistently above 50°F. Plant seeds about 1/4 inch deep in seed trays. Germination typically takes 14 to 30 days under warm conditions.
Space plants 24 to 36 inches apart to ensure adequate air circulation and growth. Provide full sun exposure for at least six hours daily. Water consistently, aiming for one to two inches per week without waterlogging the roots. Apply organic mulch around the base to retain moisture and suppress weeds while feeding regularly with a balanced fertilizer.
Monitor for aphids, spider mites, whiteflies, and pepper weevil by inspecting leaves frequently; use insecticidal soap or neem oil if infestations occur. Prevent bacterial leaf spot, pepper mosaic virus, and phytophthora blight through crop rotation and clean tools. Harvest fruits 90 to 120 days after planting when they turn deep red and feel firm.
