Phalaenopsis Root Rot Recovery: Repotting and Feeding Strategy

Cycle of Root Death and Regrowth

After cutting the spike post-bloom, your Phalaenopsis lost roots repeatedly while leaves stayed healthy. New leaf growth now signals a recovery window—if you fix the root environment.

Essential Repotting

1. Fresh orchid bark mix (not moss, not soil).
2. Remove all old medium; wash roots.
3. Trim every mushy root.
4. Repot in appropriate-sized plastic pot.
5. Weak weekly feed: ¼ tsp balanced fertilizer per gallon.

Aerial Roots: Leave Them

They're normal. Low humidity may stall their tips, but they're not the priority. Focus on pot roots.

Humidity Tray Helps

If aerial roots desiccate, a humidity tray (pebbles + water, pot above water line) benefits the whole plant.

Key Principle

"Weekly, weakly" feeding + annual repotting + dry-between-waterings = sustainable root health.
