1. Watering time

Spring: the temperature is suitable in spring, generally at 15-25 ℃, so the watering frequency should be increased appropriately, watering once every 5-7 days

Summer: the temperature is high in summer and the water evaporates quickly. It can be watered once every 2-3 days. At the same time, pay attention to spraying water on the leaves in the morning and evening to keep the plants green and avoid exposure at the same time

Autumn: the amount of watering in autumn is similar to that in spring. If the environment is dry, appropriate amount of water can be sprayed. Generally, if it is not dry, it is not poured. If it is poured, it is poured thoroughly

Winter: in winter, the temperature is low, the physiological action speed slows down, and the water evaporation is also slow. There is no need to rush to water. Generally, it can be watered once from half a month to January, or spray water on the leaf surface to keep the basin soil dry

2. Water quality selection

Rain water or river water can be used for irrigation. If tap water is used, fill the container with water in advance and dry it in the sun for 2-3 days. Watering can be carried out after chlorine and other chemicals in the water volatilize
