Water in spring and autumn, preferably before sunset at night. Summer can choose to water in the morning or evening, try not to water in the high temperature afternoon.
At ordinary times, you can water the Rohdea japonica properly. You need to water it slowly every time. Wait until the water seeps into the soil, and then pour until there is water flowing out from the bottom of the basin, so as to ensure that the water is fully poured. If the air is dry indoors, spray the Rohdea japonica branches and leaves with water close to the room temperature.
Evergreen is most afraid of waterlogging by standing water, usually enough water can be poured, too much water easy to cause rotten roots. In winter, it is generally required to move into the room for maintenance. If it is cultivated outdoors in South China, water should be poured before it enters winter, which is beneficial for the root system to absorb nutrition, store water, and it is more conducive to its safe winter. If not watered in winter, it will easily lead to yellow scorch of the leaf tip and even wither of the whole plant. Pay attention not to get wet during flowering, and put it in a dry and ventilated place.
Generally, water once every 3-4 days. In the early and late summer, water around the flowerpot and on the ground. It's better to spray wash or scrub the leaves with warm water every week to keep the color of stems and leaves fresh green and green all the year round.
