Troubleshooting
Lamellate Vanda problems — and how to fix them
Lamellate Vanda (Vanda lamellata) 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.
Root rot from poor drainage
If roots are confined in a pot with moisture-retentive medium, they rot rapidly. Transition to a basket culture with coarse bark or bare-root hanging to maximise aeration. Remove rotted roots with sterile scissors and dust cuts with cinnamon before rehanging.
Mealybugs
White, cottony mealybug clusters appear at leaf axils and along roots. Remove manually with a cotton swab dipped in isopropyl alcohol, then treat the whole plant with neem oil or insecticidal soap solution. Repeat weekly for 4–6 weeks to break the life cycle.
Insufficient flowering
Inadequate light is the most common reason Vanda lamellata fails to bloom. Provide the brightest possible filtered light and allow a modest temperature drop of 5–8°C between day and night in autumn to trigger flower spike development.
