White Mold on Phalaenopsis Mix: Salt or Fungus? Repot to Be Safe

Surface Mold vs. Salt

Scrape surface: shallow = fertilizer salt; deep = mold. Either way → repot.

Repotting Steps

1. Medium bark, same-size pot (or clean old).
2. Remove plant, clean roots, cut mushy ones.
3. 1 in bark in pot, lower roots, fill around, base of bottom leaf at rim.
4. Tap/press to settle.
5. Water thoroughly, then warm shade 2–3 weeks (mist daily, no water).

Why Repot

Fresh bark restores aeration. Annual repotting prevents this.
