Capped Catasetum problems — and how to fix them
Capped Catasetum (Catasetum pileatum) 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.
Water-filled new growth funnels causing rot
Water collecting in the funnel of newly emerging growth can trigger bacterial or fungal rot at the crown. Water at the base and allow foliage to dry quickly; apply diluted fungicide preventatively during the early growth phase.
Root acidification from old medium
Decomposing bark acidifies with time and damages roots. Repot annually without fail, replacing the medium completely. Never leave plants in the same substrate for more than a year.
Accordion-pleated foliage
Uneven watering during pseudobulb development leads to wrinkled, accordion-folded leaves. Water abundantly and consistently during the active growth phase to allow uniform expansion.

Most capped catasetum issues are care-mismatch, not bad luck. Dial in the basics:
