What soil is best for orchids? A detailed guide to soil mixing methods

I. Soil requirements

Different orchid varieties prefer different potting soils. But overall, they all like soil that is rich in nutrients and sufficiently breathable and well-draining. This is because such soil can provide enough nutrients to help them grow, and it does not easily become waterlogged, which reduces the chance of root rot.

II. Mixing methods

1. You can use a potting soil made by mixing three parts leaf mold, one part mountain soil and one part red soil. This soil has a very high nutrient content and is very beneficial to its growth.

2. You can also use a potting soil made by mixing three parts garden soil, five parts leaf mold or peat soil, plus one part orchid stone. The advantage of this soil is that it is very breathable and well-draining, which is very beneficial to the root growth of the plant.

3. You can also use a potting soil made by mixing two parts coarse river sand and three parts leaf mold. Note that the river sand must be the coarser kind, as this can increase the breathability of the potting soil.

4. If you are caring for an epiphytic orchid, you can use materials such as decayed tree bark, brick granules, tree fern roots and expanded clay pellets, mixed together to make its growing medium.
