The best time to water the plum is in the morning or in the evening. Avoid the hot noon. If it is in the flowering period, watering it in the morning is the best way to make the soil fully absorb water and keep the flowers bright.
It needs to be watered frequently for maintenance, and the soil should not be dried. It can also be watered in the air properly to provide a humid environment for its growth.
Generally, keep the soil slightly wet. It needs enough water in the growing period, so it needs a lot of water. But the amount of water should not be too much, so as to avoid ponding and root rot. In spring and summer, due to the hot temperature, the amount of water can be increased appropriately. The lower temperature in autumn and winter can reduce the amount of water.
In spring and autumn, the temperature is suitable. Generally, water once every 3-5 days to ensure that the soil is not dry. In summer, the temperature is high and the water evaporation is large. It is better to water 1-2 times a day. Also spray water on the blades as a measure of water replenishment. In winter, the temperature is low, and its demand for water is not high. It can be watered in a small amount or even not.
