Seedling
3-4 weeksSmall plants with 2-4 true leaves, tender and delicate
Keep soil warm (75-85°F), maintain high humidity, provide bright indirect light. Water gently to avoid damping off. Start seeds indoors 6-8 weeks before last frost.
Vegetative
4-6 weeksPlant grows 12-18 inches tall with bushy foliage and developing branch structure
Transplant outdoors after last frost. Pinch growing tips if desired to encourage bushier growth. Maintain consistent moisture and warmth (65-80°F). Begin light feeding with balanced fertilizer every 2-3 weeks.
Flowering
3-4 weeksSmall white flowers appear at leaf axils, with many blooms along the plant's upright stems
Ensure adequate sun and warmth for good pollination. Maintain steady watering; fluctuations cause flower drop. Switch to higher-potassium fertilizer (like 5-10-10) to support fruiting. Pollinate by hand if indoors.
Fruiting & Ripening
4-8 weeksPods develop upright on stems, initially green, gradually turning to deep red. Plant becomes laden with peppers, creating ornamental effect.
Continue consistent watering and feeding. Support heavy branches with stakes if needed. Reduce nitrogen to avoid excessive foliage at expense of peppers. Allow peppers to fully ripen for best flavor and color.
Harvest & Drying
Ongoing through fall or until frostFully red peppers ready for harvest or can be left on plant to dry naturally. Plant remains productive in warm climates.
Harvest peppers by cutting stems; can be used fresh or dried. For drying, leave on plant in warm, dry weather or hang bunches indoors. Seeds can be collected for next season.
