The kumquat is an excellent variety of the Jin Tan species in the genus Fortunella, subfamily Aurantioideae, family Rutaceae. It originated in China and is now widely distributed in the Qinling Mountains and the area south of the Yangtze River. Its peel is tender and crisp, and it is sweet and juicy when eaten, making it a fine delicacy. Many households also grow kumquats as potted plants. So how should a kumquat tree be cared for?

I. How to Care for a Kumquat Tree

1. Kumquats prefer relatively fertile, loose soil, ideally acidic sandy soil. If growing kumquats in pots, acidic humus soil will do.

2. When fertilizing, try not to use nitrate nitrogen fertilizer, use less potassium chloride and switch to potassium sulfate, and attach importance to the use of organic fertilizer. At the same time, master the principles of shallow application for shallow roots, deep application for deep roots, shallow application in spring and summer, deep application in autumn and winter, and deep application of phosphorus and potassium fertilizers. Fertilization should be carried out during the budding stage, fruiting stage, harvesting stage and overwintering stage. Fertilizers are mainly phosphorus, nitrogen and potassium fertilizers.

3. For orchard planting, the best time to plant kumquats is in March each year. The climate warms up during this period, which is very beneficial to the survival of kumquats. After the kumquat seedlings emerge, check promptly for dead or weak seedlings and replant them in time.

4. Kumquats like a humid environment but are averse to waterlogging. During the growth and development period, cultivated kumquats only need to keep the potting soil moderately moist. Do not water too much and cause waterlogging, which can easily lead to root rot.

5. The main pests and diseases of kumquats include canker disease, anthracnose, citrus swallowtail butterfly and several others. When abnormal symptoms appear on kumquats, promptly determine the cause so as to prescribe the right remedy.

II. The Main Value of Kumquats

In addition, they also contain a variety of trace elements beneficial to the human body. In traditional Chinese medicine, it is said to be able to regulate qi and relieve depression, resolve phlegm and quench thirst, and aid digestion and sober one up.

Kumquats have a very long cultivation history in China. Han Yanzhi of the Song Dynasty recorded in the “Jupu” (Treatise on Oranges): “Kumquats come from Jiangxi, and northerners do not know them. They first appeared in the capital Bian during the Jingyou era, and because Empress Wencheng was fond of them, their price became high and they were valued.” Today the main production area is the Yangshuo region, with a relatively large output, but the capacity for deep processing of kumquats is insufficient, so they can only be sold as fresh fruit.

The above is some relevant knowledge about kumquats. When caring for kumquats at home, be sure to be a little more careful and patient. If you can eat kumquats you have grown yourself, it is indeed a kind of happiness.
