Peppers thrive on warmth and patience. For consistent results, sow seeds 8–10 weeks before your last frost date.
Keep trays on a heat mat and maintain 80–85°F soil temperature. Lightly cover seeds and mist daily to prevent dryness.
Once seedlings appear, provide strong light and avoid overwatering.
