Troubleshooting
Three-Coloured Vanda problems — and how to fix them
Three-Coloured Vanda (Vanda tricolor) is generally forgiving once you match its basics, but a few issues come up again and again. Here is what each one looks like, why it happens, and the fix.
Refusal to bloom
Light is the usual limiter. Without bright light and some direct sun the plant grows leaves but skips flower spikes; move it brighter and harden it gradually.
Limp, hollow-looking roots
Dehydration or persistent low humidity. Increase watering frequency and humidity so the velamen rehydrates and plumps between soakings.
Crown or basal rot
Water trapped in the crown or roots left wet leads to soft black tissue. Water early in the day, keep air moving, and never let the medium stay soggy.
Leaf-tip dieback and salt crust
Fertiliser salt accumulation on roots and leaf tips. Flush regularly with plain water and dilute feed more.
