1. Soil: when breeding, the soil should have good air permeability and drainage, and contain humus, which can be mixed with coarse sand and garden soil mixed with appropriate amount of rotten leaf soil, so that it is not easy to accumulate water and the nutrients are sufficient, which is more conducive to growth.
2. Temperature: the cold resistance of Huanglan is not high, and it should be maintained in a warm place. The temperature in winter should also be above 5 degrees, otherwise it will be easily frostbitten and affect the recovery in the next year. However, in summer, when the temperature is high, we should also pay attention to more ventilation and watering.
3. Fertilization: fertilization should be applied frequently in the growth period, once every two weeks. In addition, fertilizer should be diluted with water first to avoid high concentration of burning plants.
4. Light; it likes light but can't stand strong light, so it should be shaded in summer to avoid strong light burning plants. However, other seasons can accept the full day's light, and it will be better if the light is sufficient.
The yellow orchid mainly propagates by sowing. It is usually planted in spring. It can germinate about one month after planting, and can be transplanted after the seedlings are stable. In addition, the method of grafting can also reproduce, but it is not as good as the growth of seeded seedlings. When grafting, use Huangshan yellow orchid or Tianmu yellow orchid as rootstock.
