Cryptanthus acaulis problems — and how to fix them
Cryptanthus acaulis (Cryptanthus acaulis) 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 rot from a wet mix
The commonest killer. Use a gritty, fast-draining medium, water the soil sparingly, and never let the pot sit in standing water.
Brown leaf tips
Low humidity or mineral and fluoride build-up from tap water. Raise humidity and water with rain or filtered water.
Loose, stretched rosette
Too little light makes the flat star open up and lose its tight form. Move to brighter indirect light.
Decline after blooming
Each rosette flowers only once and then fades. This is natural; allow the offsets to develop and they will replace the parent.
