1, the basin soil should not be too short of water. Kumquat is a southern tree species and likes warm and humid environment. In the process of its growth and development, it is necessary to ensure sufficient water, but not to make plants too short of water. Especially in the winter fruit-bearing period, the pot soil is too dry for a long time, which is easy to cause the fruit to fall due to lack of water. Plant flowers at ordinary times, and reduce watering in winter to prevent frostbite at the roots. For controlling watering in winter, we should also master it reasonably according to the actual situation. If the indoor temperature is relatively high, the plants will not sleep in a warm environment, and the water will evaporate quickly. At this time, it is necessary to replenish water in time, and do not let the basin soil be too dry, so as not to cause the plants to lack water and cause the phenomenon of falling leaves and fruits.

2, watering too much is easy to rot the roots. It is said that too little water in the basin soil will do some harm to plants. Similarly, too much watering will make the pot soil too wet, which is also not conducive to the overwintering of plants. In winter, the temperature itself is relatively low, so it is easy to freeze the root system when watering too much, and then the root system will be suffocated by hypoxia after accumulating water in the basin. Because the root system also needs to breathe, it can't breathe normally, and its ability to absorb nutrients gradually weakens. In severe cases, it will cause root rot, and finally lead to the yellowing of plant leaves until the leaves fall and the fruit falls.
