Vanda 'Robert's Delight' problems — and how to fix them
Vanda 'Robert's Delight' (Vanda 'Robert's Delight') 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.
No flowers despite healthy growth
Almost always too little light. Vandas need very high light — move to your sunniest spot or add strong grow lights to trigger blooming.
Shriveled, gray aerial roots
Insufficient water or humidity. Soak roots until they turn green and plump, and raise ambient humidity for these exposed roots.
Yellowing or dropping lower leaves
A few aging leaves are normal; rapid leaf loss signals root rot from staying wet too long or cold, damp conditions. Improve airflow and drying time.
Limp leaves and stalled growth
Often cold stress below about 15°C. Keep it consistently warm; vandas resent chills and sudden temperature drops.
