1. Substrate: the selection of substrate is very important. The mixture of peat soil, sawdust and grain stone can be used for cultivation to ensure good ventilation and drainage effect. It can not make the bulb difficult to breathe, and the growth is hindered, so it is difficult to achieve vigorous effect..
2. Light: the demand for light is different in different seasons, so it should be given daily, but it should not be exposed to the hot sun, otherwise the plant is prone to sunburn. Because of the different intensity of sunshine in different seasons, so in spring, summer and autumn in the semi - overcast environment, winter is to give enough sunshine, full contact to promote growth.
3. Water: ensure the application of water. In the hot summer and autumn, water should be applied every day until the bottom of the flowerpot flows out. In the season with less water demand, it should be applied once every 3-5 days, as long as the normal water supply can be ensured
4. Temperature: suitable for growing in high temperature and humidity environment, and the temperature in winter shall not be lower than 15 ℃. Spray water to the surrounding area regularly to keep the humidity around 80%.
Under the condition that the surrounding temperature is suitable and sufficient nutrition is applied before flowering, it can be opened for about one month. The maintenance method is unreasonable and the opening time may be shortened.
