Harvest Tips
Harvest fruit when fully colored (bright pink) and slightly soft to pressure, approximately 3-4 weeks after flowering. Cut with a sharp knife, leaving 1-2 inches of stem. Fruits do not ripen significantly after harvest. Peak season is typically summer to early fall. A mature plant can produce 20-40 fruits per year.
Fun Facts
- 🌱 Dragon fruit flowers bloom at night and last only until dawn, making them a spectacular but fleeting display often featuring in tropical gardens.
- 🌱 The plant is an epiphytic cactus, meaning it naturally grows on trees in tropical rainforests rather than in desert soil, which is why it requires more moisture than typical cacti.
- 🌱 Dragon fruit is native to Central America but is now more widely cultivated and known from Southeast Asia, particularly Vietnam, which produces and exports significant quantities globally.
