Dark Catasetum problems — and how to fix them
Dark Catasetum (Catasetum tenebrosum) 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 waterlogged medium
The medium must never become soggy — excellent drainage is critical. Use bark or sphagnum-perlite mixes, ensure the substrate dries appropriately between waterings, and apply preventative fungicide when repotting.
Water collecting in new growth
Water pooling in the funnel of emerging leaf growth can cause bacterial rot. Direct water to the base of the plant and ensure air movement dries foliage quickly. Apply dilute fungicide preventatively in warm, humid conditions.
Spider mites during active growth
Spider mites attack the leaves during the growing season, especially in drier conditions. Maintain adequate humidity, ensure strong air movement, and treat at first signs of fine webbing with insecticidal soap or neem oil.
