Watering should be done before 10 a.m. or after 4 p.m. in growing season. In winter, it is better to water at noon when the temperature is a little higher.
When watering, the difference between water temperature and soil temperature shall not exceed 5 ℃. It can spray water to the leaves early and late, and also spray a small amount of water to the basin soil. In addition, kumquat likes acid environment. It can spray 0.2% - 0.3% urea and 0.2% potassium dihydrogen phosphate mixture to the leaves, or add 0.2% ferrous sulfate to improve the pH. In rainy season, the water in the basin shall be dumped in time. If you put it outdoors in summer, you'd better use bricks to pad up the flowerpot to facilitate drainage.
The watering of Kumquat trees should be more and less after autumn. Water less in winter, but as soon as the pot is dry, it needs to be watered immediately. From the flowering stage to the fruiting stage, special attention should be paid to watering. Do not allow the basin soil to be too dry or too much water to avoid falling flowers and fruits. Therefore, the basin soil should be kept dry and slightly wet.
In spring and autumn, water should be poured once a day, and water should be sprayed on the leaves once a day to increase the air humidity. According to the water content of basin soil in early spring and late autumn, water once every 2-5 days. In summer, water 2-3 times a day and spray water on the ground. But avoid spraying water at flowering stage to prevent rotten flowers and affect the results. If the soil is dry, it can be watered again on the same day. In winter, water should be reduced appropriately, about once in 7 days.
