5) Add more air to the roots

Orchids like to have roots “in the air”.

You can:

• remove any plastic sheaths from the vase

• choose a transparent vase with holes

• cut off rotten or black roots before repotting

 Healthy roots are green or silvery.

 6) Add ambient humidity

Don't spray the leaves directly: you risk fungus.
Better yet:

• Place the plant on a tray with expanded clay and water (without the pot touching the water)
