Orchid Crown Rot & Repotting Media Options (Singapore)

orchid

Yellow leaf area + water droplets = water in crown → fungal infection. Remove affected tissue, seal cuts with powdered fungicide. Dry leaves fast after watering (fan helps).

Follow-Up: Repotting Media Constraints

Don't use sphagnum moss — keeps mix too wet (symptoms match).
Crumbling/black roots = rot from mix issues.
Plastic pots with many holes = good.
Hard to find peat/perlite/fir bark? Try coconut fiber, osmunda, tree fern fiber.
Google "Singapore Orchid Growers" for local suppliers/advice.
