Soil selection and treatment Orchids have high requirements on soil, and soil with good air permeability and strong drainage should be selected. Orchid soils commonly used in northern areas include carrion soil, coarse sand, perlite, etc. Before planting, the soil needs to be disinfected. Treatment to prevent the occurrence of pests and diseases. Temperature and light The temperature in winter is low in northern regions. Special attention should be paid to temperature and light during orchid breeding. The following are some suggestions: 1. Temperature: The most suitable temperature for orchid growth is 18-28 ° C. In winter, the indoor temperature should be maintained at 10 ° C. Above 10 ° C, if the indoor temperature is too low, you can use heating or air conditioning to adjust.
2. Lighting: Orchids prefer semi-cloudy environments. Direct sunlight should be avoided in summer, and lighting time should be increased in winter.
