If too much water has been given, stop watering, take the plant out, let it air-dry for two or three days, and then move it back into the pot. In addition, during the plum rain season, drainage measures should be done well. Generally, water once a day in summer, as much as possible in the evening, and at other times water according to the dryness and moisture of the potting soil.
