Watering is very important in the growth period of orchids. Once water shortage or water supply is not appropriate, it will lead to poor growth, root rot and black spots on leaves. The best time to water is in the morning or in the evening. Pay special attention not to water at noon. When watering, do not directly water at the head. You can choose to use clean, pollution-free, acid water to water flowers. Watering should also pay attention to the method, generally choose spray method, which can increase the humidity in the air, also can wash the leaves by the way. The temperature of water also needs to be noted. In winter, it is not allowed to use too cold water. It should be placed indoors for a while. Water temperature in 15 ℃ is most suitable for watering, of course, summer can not use too high temperature water
Ordinary farmyard manure can be used as fertilizer, but it should be piled up for more than a year before fertilization. When fertilizing, pay attention to fertilizing along the edge of the basin. Do not let the fertilizer touch the root or the leaves. When applying fertilizer, you can also choose to spray fertilizer on the leaf surface, which can reduce the damage of fertilizer to the root of orchid and make orchid absorb nutrition better. When orchids begin to grow and develop, they need less fertilizer. They need to apply thin liquid fertilizer once every ten to fifteen days. At this time, fertilization should be based on natural organic matter, which can make its growth more robust.
The place where orchids are planted can choose to be in the place where there is sunshine but the sun is blocked, and the air should be clean and relatively high humidity should be maintained. The temperature should also be noted that when the temperature is lower than zero in winter, it should be moved 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, it is necessary to promote the maturity of the plant through heating. Never keep heating 24 hours a day. The heating temperature should not be too high, not more than 25 ℃.
