1. What are the requirements for soil for growing orchids?

1. Good air permeability: Orchids have fleshy roots and are suitable for growing in soil with good air permeability. If the soil permeability is very poor and air cannot circulate, the roots of the orchid will not be able to grow normally. Therefore, you need to use soil with good air permeability to grow orchids.

2. Good drainage: The roots of orchids are afraid of waterlogging. If they are kept in waterlogged soil for a long time, their roots will rot and will not be able to absorb water and nutrients, causing the plants to grow poorly. Therefore, you need to use soil with good drainage and not prone to waterlogging to grow orchids.

3. Adequate fertility: The growth of orchids requires nutrient support, so it is advisable to use soil with sufficient fertility when maintaining it. This will allow it to absorb more nutrients and grow better. If it is grown in poor soil for a long time, it will have yellow leaves due to insufficient nutrient supply.

4. Weakly acidic: Most varieties of orchids prefer acidic soil, and it is advisable to use soil with a pH between 5.5-6.5 when caring for them. However, this does not apply to all orchids. Before raising it, you should first make sure that the variety you want to raise likes slightly acidic soil, and then use slightly acidic soil to grow it.

Orchids can also be grown in soil. However, don't just use soil to plant orchids. You should mix the soil with other soils such as leaf mold, pine needle soil, river sand, etc. and use it as the growing medium for orchids. This can increase the air permeability and nutrient content of the soil, making it more suitable for orchid growth.
