Managing Aerial Roots on Phalaenopsis Orchids

Understanding Aerial Roots

Roots growing above the potting mix develop a protective covering (velamen) to prevent drying. This is normal—they're not dead.

Proper Repotting Technique

1. Soak fresh orchid mix (fir bark-based) for 1–2 hours.
2. Unpot plant, rinse roots thoroughly.
3. Remove only mushy roots—keep all firm roots.
4. Repot into plastic pot with ample drainage.
5. Incorporate aerial roots into the mix if possible (may require removing a lower leaf).

Key Principle

Healthy roots are firm and turn green when wet. The velamen stores water and nutrients. Never cut healthy root tips—growth occurs there. Proper repotting gives roots the aeration and moisture balance they need.
