Brassia Rex 'Christine' Rot Spot: Surgical Removal and Prevention

Question:

Rot spot on one bulb—fix and prevent recurrence?

Answer:

Cut out rotted bulb portion until clean tissue visible. Seal wound with powdered sulfur to prevent reinfection. Rot causes: minor tissue injury → fungus/bacteria; old mix retaining too much moisture. If not repotted in past year with standard orchid mix, repot at new growth emergence.

Note: Correct name = Brassia Rex 'Christine' (Rex = hybrid, Christine = clone).
