Cryptanthus 'Black Mystic' problems — and how to fix them
Cryptanthus 'Black Mystic' (Cryptanthus 'Black Mystic') 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.
Colour fading to green-bronze
The most frequent complaint. Too little light strips the blackish-purple pigment; move to bright indirect light to restore the dark tone and silver bands.
Crown or root rot
From a wet mix or water sitting in the rosette. Use a fast-draining medium, water the soil only, and avoid waterlogging.
Brown, crispy leaf tips
Low humidity or salt and fluoride from tap water. Raise humidity and switch to rain or filtered water.
Mother rosette declines after flowering
Normal bromeliad behaviour — each rosette blooms once then fades while offsets take over. Let pups mature on the parent first.
