Troubleshooting
Tessellated Vanda problems — and how to fix them
Tessellated Vanda (Vanda tessellata) 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.
Sparse or absent flowers
Insufficient light is the prime cause. This species needs strong, partly direct sun; increase light and it flowers far more freely.
Wrinkled, dehydrated roots
Underwatering or low humidity. Water more often and raise humidity so the velamen rehydrates and the roots stay plump and green at the tips.
Soft black root or crown rot
From wet, airless conditions. Keep roots open to the air, water in the morning, and run a fan; remove and treat any rotted tissue promptly.
Sunscald patches
Even this sun-tolerant species can scorch if moved abruptly into full midday sun. Acclimatise gradually to harder light to avoid bleached, sunken spots.
Prevent tessellated vanda problems before they start
Most tessellated vanda issues are care-mismatch, not bad luck. Dial in the basics:
