Phalaenopsis Blooming But Leaves Dying: Root Rot in Degraded Mix

Spectacular bloom + yellowing lower leaves = classic sign of collapsed potting mix suffocating roots. The plant sacrifices old leaves to feed flowers.

Holding Pattern (During Bloom)

• Cut water drastically—let mix nearly dry. Better dry than wet.
• Do NOT repot now—disturbs roots, drops flowers.
• East window, morning sun, 60–85°F.

Post-Bloom Repot (Urgent)

1. Soak fresh orchid mix (bark/perlite/charcoal).
2. Unpot, rinse roots, remove ALL mushy/stringy roots.
3. Pot in holey plastic pot, tap mix in, drain well.
4. Wait 1 week, then water weekly.

Water Clarification

Filtered water is fine unless it strips minerals (avoid pure/distilled/RO). Orchids need calcium/magnesium. "Protek" supplement helps if water is too pure.
