In order to keep the basin soil moist, it is necessary to spray water on the leaves in time in dry weather to improve the air humidity and promote the healthy growth of plants. The air humidity in growing period should be controlled at about 60% - 80%. At the same time, timely drainage, avoid ponding and rain, otherwise easy to cause rotten roots. In winter, the basin soil is a little dry, you can spray water to the leaves once a week.
