Queen of Orchids problems — and how to fix them
Queen of Orchids (Cattleya dowiana) 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.
Bud blast
Flower buds yellow and drop before opening due to sudden temperature drops, cold draughts, ethylene from ripening fruit, or low humidity. Keep away from fruit bowls and heating vents; avoid moving the plant once buds are visible.
Sheath rot from trapped moisture
Water or condensation inside the papery sheath causes bacterial rot that destroys the developing inflorescence. Slit the sheath carefully with a sterile blade after it appears, allowing air circulation inside.
Pseudobulb shrivelling
Wrinkled or shrunken pseudobulbs indicate underwatering or root loss. Check for rotten roots and repot if necessary. During active growth, ensure thorough watering. Some minor shrivelling during the dry rest is normal and resolves when watering resumes.
