Seedling
3-4 weeksSmall seedlings with 2-4 true leaves emerge; plants are tender and delicate
Start seeds indoors 6-8 weeks before last frost. Keep soil warm (70-80°F) and moist. Provide bright light and gentle air circulation. Harden off before transplanting outdoors.
Vegetative Growth
4-6 weeksPlant develops multiple stems and compound leaves; reaches 12-24 inches tall
Transplant outdoors after all frost danger passes. Provide consistent moisture and feed with balanced fertilizer every 2-3 weeks. Support with stakes if needed. Prune to encourage bushiness.
Flowering
4-8 weeks, recurringSmall white or pale yellow flowers appear in clusters; flowers are delicate and self-fertile
Maintain consistent watering and moderate nitrogen. Avoid excessive shade which reduces flowering. Light misting can improve pollination in dry conditions. Flowers appear continuously in warm weather.
Fruiting
3-4 weeks per fruit setSmall round fruits develop inside paper-like husks, gradually turning yellow or orange as they mature
Continue regular watering and feeding with phosphorus-rich fertilizer to support fruit development. Fruits are protected by husks which split when ripe. Maintain warm temperatures above 60°F.
Harvest
Continuous through growing seasonFully mature fruits fall from plant or separate easily when gently pulled; husks are papery and tan
Harvest fruits when fully yellow/orange and husks are dry. In cooler climates, harvest before first frost or bring entire plant indoors to continue ripening. Fruits store several weeks in cool conditions.

Harvest Tips
Pick fruits when the papery husk splits and fruit inside is fully yellow or orange. Fruits can be harvested when they fall naturally or gently pulled from the plant. In cool climates, harvest before the first frost or pull entire plant and hang to allow fruits to ripen indoors. Fruits are mature when the husk is dry and tan-colored. Store harvested fruits in a cool, dry place for several weeks.
Fun Facts

- 🌱 The name 'xanthocarpa' comes from Greek words meaning 'yellow fruit,' referring to the distinctive golden-yellow color of ripe berries.
