Seedling
2-3 weeksTiny seedlings with 2-4 true leaves emerge 1-2 weeks after planting; delicate with thin stems
Keep soil moist, provide bright indirect light, maintain warmth (70-75°F), thin to strongest seedlings if densely planted
Vegetative Growth
6-8 weeksPlant develops robust woody stems, increasingly large leaves, and bushy branching structure; reaches 1-2 feet tall
Water regularly, feed monthly with balanced fertilizer, pinch growing tips to encourage branching, provide support or stakes if needed
Flowering
4-6 weeks, repeating cyclesSmall yellow flowers with purple-streaked petals and yellow centers appear along branches; self-fertile with minimal pollinator needs
Maintain consistent watering, reduce nitrogen fertilizer to promote flowering over leaf growth, encourage pollinating insects, do not over-prune
Fruiting
6-8 weeks per fruiting cycleFlowers develop into green berries enclosed in distinctive papery lantern-like husks; berries gradually yellow and sweeten
Support branches with fruit weight, maintain even watering to prevent cracking, protect from excessive rain, apply balanced fertilizer every 3-4 weeks
Harvest & Maturity
Ongoing (3-4 months or longer)Golden-yellow fruits fully mature within husks; plant continues producing new flowers and fruit in warm climates
Harvest ripe fruits regularly, deadhead spent flower clusters to encourage continued production, prune lightly to maintain shape and productivity

Harvest Tips
Pick fruits when fully yellow and slightly soft; they will continue to ripen slightly after harvesting. Fruits develop best flavor when allowed to fully mature on the plant. Harvest regularly to encourage continued production. The papery husk naturally dries and protects the fruit; store husked fruits in the refrigerator for up to 2 weeks. In Hawaii, peak harvest is typically late summer through fall.
