Harvest Tips
Harvest Meiwa kumquats from fall through winter when fruits are fully golden-orange and slightly soft to pressure. Gently twist and pull fruits from the branch, or use clean shears. Fruits can be picked slightly early and ripened at room temperature, though tree-ripened fruits have superior flavor and sweetness. Harvest regularly to encourage continued production. Fruits keep 2-3 weeks at room temperature or up to a month refrigerated.
Fun Facts
- 🌱 Meiwa kumquats were first cultivated in Japan and China centuries ago; the name 'Meiwa' means 'bright harmony' in Japanese, reflecting the fruit's combination of sweetness and tartness.
- 🌱 Unlike most kumquats where the skin is bitter or sour, Meiwa's skin is sweeter than the flesh—you eat it whole, skin included, like a grape or berry.
- 🌱 A single Meiwa kumquat tree can produce hundreds of fruits per season, and they hang on the tree well, often remaining ornamental through winter holidays.
