Orchids are epiphytes—in nature, they cling to trees with their roots exposed to air. That's why they need a loose, airy growing medium instead of regular potting soil. Sphagnum moss is a favorite choice.
When to Repot
- Every one to two years
- After blooming has finished
- When the moss breaks down and stays soggy
- When roots are crowded or growing out of the pot
What You'll Need
- Sphagnum moss (soaked in water for 15–30 minutes)
- A pot with good drainage, often clear plastic so you can see roots
- Clean, sterilized scissors
Step by Step
- Gently remove the orchid from its pot and loosen the old medium.
- Trim any mushy, brown or hollow roots. Healthy roots are firm and green or silvery.
- Squeeze excess water out of the soaked moss.
- Wrap moss loosely around the roots and place the plant in its new pot.
- Don't pack the moss too tightly—roots need air.
Aftercare
Wait about a week before watering again, keeping the plant in bright, indirect light. Sphagnum holds moisture well, so water less often than you would with bark—only when the top feels dry.
