If you want to water the emerald tree, you should first put down the color of the pot soil. If there is a slight whiteness, you should water it in time. Or through the weight of the flower pot to determine whether it needs watering, if it's obviously lighter, also need to make up water as soon as possible.
It should be watered once as much as possible, slowly from the edge of the flowerpot, to avoid the situation that the surface soil is wet and the deep soil is dry. High temperature and dry weather, need to increase the frequency of watering, every morning and evening also need appropriate water spray. When the temperature is low, the water should be watered less, and there should be no water accumulation, and the water temperature should be close to the room temperature, if too cold water is used, the root system of the plant will be frostbitten.
The temperature in spring and autumn will not be too high or too low, and the time of watering should not be too concerned, but attention should be paid to watering in summer and winter. The temperature in summer is very high. Water in the morning and evening, not in the middle of the day when the sun is strong. Winter climate is more severe, should choose at noon, otherwise it will plant frostbite.
