Fruiting

Harvest Tips
Harvest fruits when fully colored (deep orange) and slightly soft to touch, typically 4-6 months after flowering. Fruits can remain on tree for extended periods. Pick fruits individually by gently twisting, or cut with pruning shears. Cumquats are best eaten fresh immediately after harvest and store 2-3 weeks at room temperature or several months refrigerated.
Fun Facts
- 🌱 The name 'cumquat' derives from the Cantonese 'kam kwat' meaning 'golden fruit,' and is native to Southeast Asia, particularly China.
- 🌱 Unlike most citrus fruits, cumquats are eaten with the peel on, and the skin is sweeter than the juice inside, creating a unique flavor experience.
- 🌱 Dwarf cumquat trees can flower and fruit multiple times per year in warm climates, providing nearly year-round harvests in zones 10-11.
