Cultivation methods and precautions of fan-veined Cypripedium

1. Watering

Watering is very important during the growth period of orchids. Once there is a lack of water or inappropriate water supply, it will lead to poor growth, root rot, black spots on the leaves and other symptoms. The best time to water is in the morning or evening. Pay special attention not to water at noon, and do not water directly on the head. When watering flowers, you can choose clean, unpolluted, slightly acidic water. You should also pay attention to the method of watering. Generally, spraying is chosen, which can increase the humidity in the air and also wash the leaves at the same time. The temperature of the water also needs to be paid attention to. Do not use too cold water in winter. It should be placed indoors for a while. The water temperature of 15℃ is most suitable for watering flowers. Of course, you can't use water with too high temperature to water flowers in summer.

2. Fertilization

Ordinary farm manure can be used as fertilizer, but it should be piled up and decomposed for more than a year before it can be used. When applying fertilizer, be sure to apply it along the edge of the pot, and do not let the fertilizer touch the roots or leaves. When fertilizing, you can also choose to spray fertilizer on the leaves. This can reduce the damage of fertilizer to the roots of orchids and allow orchids to better absorb nutrients. When the orchid begins to grow and develop, it will not need much fertilizer, so apply thin liquid fertilizer about once every ten to fifteen days. At this time, the fertilizer should be mainly natural organic matter, which can make it grow stronger.

3. Environment

The place for planting orchids can be chosen in a place that has sunlight but is shielded from the scorching sun. The air should be clean and the air humidity should be relatively high. Also pay attention to the temperature. When the temperature drops below zero in winter, move it into a warm room in time to avoid frostbite. The temperature should be kept at 15℃ in winter and 5℃ at night. In late autumn and early winter, heating should be used to promote the maturity of the plants. Do not heat continuously for 24 hours a day, and the heating temperature should not be too high, not exceeding 25℃.
