Orchids die easily if they are not properly maintained.

Orchids are dormant or semi-dormant in winter, such as improper maintenance, it is easy to cause physiological diseases, light leaves become withered and yellow, can still germinate in spring, serious ones can lead to death, the reasons are as follows:

1. The basin soil is too dry and wet. Although orchids should greatly reduce water in winter, they should not be irrigated without watering. If the potted soil is too dry and the climate is dry in winter, the false bulbs of orchids are easy to be withered, the plants will grow badly, and the leaves will wither and die if they are heavy. In winter, orchids avoid pot soil too wet, too much water, basin soil ventilation is poor, it is easy to cause rotten roots and death.

2. Water and soil are not suitable. The best water for watering orchids is Rain Water and river water. if well water or fresh tap water is used, the basin soil is often easy to become alkaline, the soil quality becomes worse, the basin soil is hardened, the water seepage is poor, and the ventilation is poor, so that the basin soil is easy to be wet in winter, and the plant is more likely to rot roots. Therefore, the acid loose soil should be chosen in orchid pot soil, and the ph should be between 5 and 6.5.

3. Improper watering method. In other seasons, orchids should be watered in the morning or evening, while in winter, they should be watered in the noon sun for 1-2 hours, and then moved indoors after drying at the base of the leaves. As different varieties of orchids have different demands for water, watering should be treated differently in winter, such as autumn orchids should be watered thoroughly before winter, while spring orchids should be moistened but not permeable; autumn orchids do not need to be watered in heavy snow, while spring orchids are better moistened; from the Winter Solstice to Lesser Snow, autumn orchids and spring orchids can be watered without watering or mastering eight points of dry and two parts wet.

4. Improper use of pots. It is better to use the mud basin in the cultivation of orchids. The ventilation of the mud basin is better than that of the glaze basin, which is very suitable for the growth of orchids and is not easy to cause over-wetting for a long time, resulting in fewer diseases and insect pests. And the use of glaze basin, especially in winter, is often easy to rot because the basin soil is too wet.
