A new orchid has been brought to your home, and after a short enthusiasm, your plant withers and you think you can just throw it away.

What can you do to save it?

This is the right place to get advice on how to restore its beauty by making orchid potting mix yourself. Here you will find out when to repot your plant, what materials to use and how to combine them.

Orchid Potting Mix

Orchids that grow in the soil are terrestrial. However, most other orchids do not need soil, because they are epiphytes that grow in the air and take their nutrients from there.

That is why it is very important to provide your plant with the right potting media, which will enable good airflow and thus mimic the natural environment.

The best time to repot your orchid is when you notice that the roots have grown too much, the potting media breaks down (decompose) and does not look healthy, the plant becomes overlarge for the pot, and the roots rot.

The easiest way is to buy the potting mix in a special shop (like this one on Amazon) and that’s the end of the story. However, if you want to embark on an adventure and try to make it yourself, you will discover how much fun and inspiring it is at the same time.

A quality orchid potting mix should retain moisture, drain water quickly, create conditions for good airflow and also break down slowly.
