Troubleshooting
Showy Coelogyne problems — and how to fix them
Showy Coelogyne (Coelogyne speciosa) 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.
Yellowing pseudobulbs
Premature yellowing indicates overwatering or root rot in a poorly draining mix. Remove the plant from its pot, trim dead roots, allow to dry briefly, and repot in fresh bark with improved drainage. Scale back watering frequency.
Failure to reflower
Flowering is stimulated by a mild temperature drop (2–4°C below daytime) at night and a slight reduction in watering in late winter. Plants kept too warm and wet year-round produce only vegetative growth.
Mealybug infestation
White cottony masses appear at the base of pseudobulbs and in leaf sheaths. Remove with a cotton swab dipped in alcohol and treat with horticultural oil or insecticidal soap. Inspect new plants carefully before introduction.
