What soil is best for Phalaenopsis orchids? How to choose a growing medium

I saw a flower enthusiast asking what soil to use for Phalaenopsis orchids, so it is worth explaining this to the flower enthusiasts at Yuhuagu. Phalaenopsis is an epiphytic orchid, and its thick white aerial roots are exposed around the leaves. Besides absorbing nutrients from the air, they also carry out growth and photosynthesis.

If flower enthusiasts have read the previous paragraph carefully, then we should already know 2 key points: one is that Phalaenopsis is an epiphytic orchid, and the other is that its root system absorbs nutrients from the air and can also carry out photosynthesis.

So that means Phalaenopsis is not like plants in the traditional sense, where the roots obtain nutrients and water from the soil. On the contrary, Phalaenopsis also needs its roots exposed so that it can obtain nutrients and carry out photosynthesis, so flower enthusiasts should not bury all of the Phalaenopsis roots in soil.

So flower enthusiasts ask, what should be used to grow Phalaenopsis? You can use sphagnum moss, or fix the Phalaenopsis onto rotten wood.

Writing ten thousand words is not as good as one picture. Let us look at a picture of a flower enthusiast fixing a Phalaenopsis onto rotten wood.

From the picture above, we can see that without soil, Phalaenopsis can still grow and bloom normally. So if flower enthusiasts need to use a pot to grow Phalaenopsis, then we need to leave some of the roots exposed outside, and use sphagnum moss in the pot to hold it in place.
