Troubleshooting
Vanda Orchid problems — and how to fix them
Vanda Orchid (Vanda spp.) 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 overwatering or poor airflow
Roots that stay wet without drying turn mushy, brown or black. Cut away all diseased roots, treat with a copper-based fungicide, and improve air circulation and drying between waterings.
Refuses to bloom
Almost always too little light. Increase to bright direct sun, ensure a slight night temperature drop, and feed regularly during growth. Leaves should be medium green, not dark.
Shrivelled roots and crispy, limp leaves
Sign of dehydration or under-watering, common with bare-root plants in low humidity. Water more often and raise humidity with misting, a tray or a humidifier.
Root disturbance causes decline
Vandas resent having their roots damaged or disturbed; repotting or rough handling can make a mature plant stop flowering and sulk for a season or more. Move them as little as possible.
Bud or leaf drop
Sudden temperature swings, drafts or sharp humidity changes can trigger bud drop and drooping leaves. Keep conditions stable and avoid cold drafts.
