Soil, care & harvest

Prepare loose, fertile soil with a pH between 6.0 and 7.0 before starting seeds indoors six weeks before your last expected frost. Sow seeds one-quarter inch deep in seed trays, as they take fourteen to twenty-eight days to germinate. Keep the medium consistently moist during this period until strong seedlings emerge.

Space plants twenty-four to thirty inches apart to ensure good air circulation. Provide full sun exposure and water consistently, aiming for one to two inches per week, especially while fruiting. Apply a light layer of mulch around the base to retain moisture and feed the soil occasionally with balanced fertilizer.

Watch for aphids, spider mites, whiteflies, and pepper weevils; use insecticidal soap or neem oil if infestations occur. Prevent bacterial spot, anthracnose, and powdery mildew by ensuring good airflow and avoiding overhead watering. Harvest the fruit ninety to one hundred days after transplanting when they turn a vibrant yellow.
