Cryptanthus fosterianus problems — and how to fix them
Cryptanthus fosterianus (Cryptanthus fosterianus) 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.
Root and crown rot
From a saturated mix or standing water in the rosette. Use a gritty, fast-draining medium and water the soil only, letting it dry slightly between waterings.
Scorched, bleached leaves
Direct midday sun on the broad leaves burns and fades the banding. Move to bright but filtered light.
Brown leaf tips
Low humidity or salt and fluoride from tap water. Raise humidity and water with rain or filtered water.
Mother declines after flowering
Normal — the rosette flowers once then fades while offsets develop. Leave pups on the parent until they are well grown.
