Phalaenopsis Losing Bottom Leaf: Root Rot in Old Media

Yellowing Basal Leaf Signals Potting Mix Breakdown

A phalaenopsis with 3 leaves losing the lowest one (yellow from edge inward, translucent) in a kitchen with "bright but no direct light" likely has decomposed potting mix. Surface feels dry but root zone stays soggy.

Rescue Repotting

  1. Buy fresh orchid bark mix.
  2. Unpot, wash roots, trim all mushy/brown roots.
  3. Pot in clean plastic container with damp bark.
  4. Base of leaves at mix surface.
  5. Water thoroughly, wait 1 week before next watering.

Light Upgrade Needed

"Bright kitchen" ≠ enough light. Move to east window for morning sun. Higher light = larger new leaves, better blooming. New leaves should equal or exceed old leaf size.
