The most suitable temperature for cultivating lily of the valley is about 20 ℃. In summer, we should do cooling work for it. We should sprinkle water around the plant, or spray some mist like water, which can play a good cooling effect. In winter, we will move it to a warm indoor breeding.
It doesn't have very high requirements for fertilizer. It can be applied once half a year during normal maintenance period, which is enough to maintain its growth. Note that the use of fertilizer concentration must be low, the application of thick fertilizer is very easy to burn seedlings, plant growth will be very harmful.
During its growing period, water it once or twice a day, but don't keep its basin soil wet. In summer, we need to pour more water properly. Because of the high temperature in summer, the water evaporates very fast. In winter, we need to reduce the amount of water, less or no water is OK
Lily of the valley has no high requirement for light. It's best to keep it in a half shade place and let the plant receive a proper amount of astigmatism. Be careful not to be exposed to too much sun
