Troubleshooting
Blue Vanda problems — and how to fix them
Blue Vanda (Vanda coerulea) 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.
Shrivelled, wrinkled roots
Usually underwatering or chronic low humidity. Increase soak frequency and ambient humidity; healthy velamen should plump and silver between waterings.
No flowers
Almost always insufficient light. Vandas need very bright light with some direct sun; a too-dark spot produces lush leaves but no spikes.
Black, mushy roots or crown
Rot from medium staying wet or water sitting in the crown. Grow bare-root or in open baskets, water in the morning, and keep air moving.
Leaf drop from the base
Some lower-leaf loss is natural with age, but rapid yellowing and drop signals cold, wet roots or overwatering.
