1、 Watering

Watering is very important. During the growth period of orchids, once there is a lack of water or the water supply is inappropriate, it will lead to poor growth, rotten roots and black spots on the leaves. The best time to water is in the morning or evening. Pay special attention not to water at noon. When watering, you can't directly water at the head. The water for watering flowers can choose to use clean, pollution-free and acidic water. Attention should also be paid to the method of watering. Generally, spraying method is selected, which can increase the humidity in the air and wash the leaves by the way. Attention should also be paid to the temperature of water. In winter, it should not be poured with too cold water. It should be placed indoors for a while. The water temperature of 15 ℃ is the most suitable for watering flowers. Of course, you can't water flowers with water with too high temperature in summer

2、 Fertilization

Ordinary farm manure can be used as fertilizer, but it should be stacked and rotten for more than a year before fertilization. When applying fertilizer, pay attention to applying fertilizer along the edge of the basin. Don't let the fertilizer touch the roots or the leaves. When applying fertilizer, you can also choose to spray fertilizer on the leaf surface, which can also reduce the damage of fertilizer to the root of orchid and make orchid better absorb nutrition. When orchids begin to grow and develop, there is not much fertilizer needed. Apply thin liquid fertilizer once every ten to fifteen days. At this time, fertilization should be based on natural organic matter, which can make it grow more robust

3、 Environment

The place where orchids are planted can be in the place where there is sunshine but can block the hot sun, and the air should be clean and keep relatively high air humidity. Pay attention to the temperature. When the temperature is below zero in winter, move into a warm room in time to avoid frostbite. Keep the temperature at 15 ℃ in winter and 5 ℃ at night. In late autumn and early winter, we should promote the maturity of plants by heating. We must not keep heating 24 hours a day, and the heating temperature should not be too high, not more than 25 ℃
