Troubleshooting
Cryptanthus zonatus problems — and how to fix them
Cryptanthus zonatus (Cryptanthus zonatus) 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.
Crown and root rot
Caused by a soggy mix or by pooling water in the centre of the rosette. Water the soil only, use a gritty fast-draining mix, and never let it sit wet.
Browning, crispy leaf tips
Low humidity or salt and fluoride build-up from tap water. Raise humidity and switch to rain or filtered water.
Faded, washed-out banding
Too little light or over-feeding. Move to brighter indirect light and cut fertiliser back to quarter strength to restore the silver-on-bronze contrast.
Parent dies after flowering
Normal — like all bromeliads the mother rosette flowers once then slowly declines. Let the pups mature on the parent before separating them.
