How to Repot Phalaenopsis from Moss to Bark Mix

Transitioning from Moss to Bark

Repotting orchids from water-retentive sphagnum moss to a bark-based mix improves drainage and root health. The key is thorough root cleaning to prevent rot.

Step-by-Step Process

1. Soak new bark mix for several hours—dry fir bark repels water initially.
2. Unpot the plant and rinse all moss from roots under lukewarm water.
3. Inspect roots: keep only firm, healthy ones; remove mushy or stringy roots.
4. Place in a plastic pot with excellent drainage.
5. Add pre-soaked bark mix, tapping the pot to settle it around roots.
6. Allow to drain thoroughly before returning to growing area.

Why This Matters

Moss compacts over time, suffocating roots. Bark mixes maintain aeration longer. Soaking the bark beforehand prevents it from pulling moisture from the roots. This transition reduces rot risk and promotes vigorous growth.
