Office Phalaenopsis Declining: Root Rot from Aquarium Humidity and Overpotting

Diagnosis: Root Rot Likely

Buds blasted, yellow leaves with black spots/rims, mix staying moist 2 months = classic root rot. Aquarium humidity + grow light heat + large pot = anaerobic conditions.

Rescue

1. Buy orchid bark mix.
2. Unpot, wash roots, remove all mushy roots.
3. Assess: firm roots = hope.
4. Repot in small plastic pot (snug fit) with damp bark.
5. East window (morning sun) ideal.
6. Water weekly (bark drains well).
7. 65–80°F.
8. New growth in 4–8 weeks.

Leaf Loss

Yellowing leaves will drop—cut if unsightly. Focus on root recovery.
