Rhynchostylis retusa problems — and how to fix them
Rhynchostylis retusa (Rhynchostylis retusa) 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 aerial roots
Humidity too low for bare-root culture. Raise humidity well above 60% and water more often so roots stay plump between dryings.
No flower spikes
Insufficient light is the usual cause. Move to a much brighter, filtered position to encourage the long pendulous foxtail sprays.
Root and crown rot
Water lodged in the crown or dense medium holding moisture. Water early, keep airflow strong, and grow bare-root rather than in soggy potting mix.
Bud or flower drop
Sudden swings in temperature or humidity during bloom. Keep conditions warm and stable while the long spikes develop and open.
