Troubleshooting
Maikai Orchid problems — and how to fix them
Maikai Orchid (Brassocattleya 'Maikai') 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.
No flowers despite healthy growth
Requires a brief drier and cooler rest (13–15°C nights for 4–6 weeks in autumn) once new pseudobulbs mature and sheaths form. Without this temperature drop, flower buds may fail to develop inside the sheath. Also ensure light levels are high enough — low light is the most common cause of non-flowering in the Cattleya alliance.
Sheath rot (bud blast)
Water trapped inside the flower sheath creates conditions for Botrytis and bacterial rot. Pierce the sheath gently to check for blackened buds within. Avoid misting the plant and ensure good air movement around developing sheaths. Remove affected tissue promptly.
Pseudobulb shrivelling
Indicates either insufficient watering, damaged roots, or low humidity. Check the root system when repotting — grey, dry roots need more consistent moisture; blackened roots signal overwatering. A healthy root system is plump, white-grey when dry and bright green when wet.
