Kumkat Harvest Season
When harvesting the kumquat tree, the exact time will vary depending on the variety. Some varieties ripen from November to January, some from mid-December to April. Six varieties are grown around the world, but only three, Nagami, Meiwa, and Fukushu, are grown here.
Kumquats are very cold hardy down to -12°C (10°F), but even so, you should bring them indoors or otherwise protect them if the temperature drops. Cold damage to the tree can result in fruit injury or fruit deficiency, eliminating the need to harvest a kumquat tree.
