Hairy-Cupped Coelogyne problems — and how to fix them
Hairy-Cupped Coelogyne (Coelogyne tomentosa) 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.
Pseudobulb rot at the base
Caused by water pooling at the base of pseudobulbs in poorly draining media or containers without holes. Use baskets or deep pots with large drainage gaps, and ensure water flows freely through the medium every time you water.
Short or sparse racemes
Inadequate light or insufficient maturation of pseudobulbs reduces raceme length and flower count. Ensure pseudobulbs are fully developed before the winter rest, and provide brighter light in the pre-flowering period.
Scale insects on pseudobulbs
The yellowish, wrinkled surface of older pseudobulbs makes scale easy to miss. Check regularly and treat with horticultural oil. Consistent inspection during repotting prevents large infestations from establishing.
