Heart-leaf Pleurothallis problems — and how to fix them
Heart-leaf Pleurothallis (Pleurothallis cardiothallis) 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.
Dehydration and shrivelling
The cordate leaves shrivel quickly when roots dry out even briefly. Mounted plants are especially vulnerable in low-humidity rooms — move to a terrarium or mist twice daily.
Fungal spotting
Black or brown leaf spots develop when high humidity combines with stagnant air. Always pair high humidity with gentle air circulation from a small fan.
Crown rot
Water pooling in the leaf axils or at the ramicaul base encourages Botrytis and Erwinia. Water early in the day and ensure good drainage at the base of mounts.
