Light and temperature : Hi-slow, warm environment. In summer, it should be placed under the shade, or placed in a place where there is no direct light. Suitable spring and summer growth temperatures are 21 to 24 ° C during the day and 16 to 18 ° C during the night. In the winter, it is necessary to enter the greenhouse and place it in the sunny place. It is required to have sufficient light, and it is better to maintain the temperature of 10 to 13 °C in winter.
Watering and fertilization: watering should be fully watered from spring to autumn, and water is often sprayed to increase the humidity of the air, keeping the soil warm, but not using alkaline water. In the growing period, 1 to 2 times of topdressing is applied every month, and the effect of topdressing with fermented cake liquid fertilizer, manure liquid and ferrous sulfate is good. It can also be watered with a mixture of urea and superphosphate.昙花喜肥, proper fertilization can make the flower tired. In the winter, you should control the watering, the potting soil should be moderately dry, and the tablets should stop.
The silk flower is open at night, in order to open it during the day, when the flower bud is inflated, put it in the dark room during the day or cover it with black cloth and black plastic film to prevent it from seeing light. It is illuminated by light from 8:00 pm to 6:00 am the next day. After 7 to 8 days of treatment such as “turning around the clockâ€, the flowers can be opened at 8-9 am during the day.
