Mold on Orchid Moss: Why Repotting Is the Solution

Why Mold Grows on Sphagnum Moss

Blue-gray mold on surface moss indicates excess moisture and poor air flow. Moss retains water and can hide deteriorating potting mix underneath.

Complete Repotting Procedure

1. Buy coarse fir bark orchid mix (½" particles) from Lowe's, Home Depot, or garden centers.
2. Soak mix 1+ hour before use.
3. Unpot plant, rinse roots, remove mushy (dead) roots.
4. Use pot with many drainage holes; size up if roots are healthy.
5. Place roots in pot, add wet mix, tap pot to settle.
6. Repot after each flowering to prevent mold and root rot.
