Entire-Lipped Catasetum problems — and how to fix them
Entire-Lipped Catasetum (Catasetum integerrimum) 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.
Premature leaf drop or rot in dormancy
Continuing to water after leaves naturally yellow and fall triggers root rot. Once pseudobulbs are fully formed and leaves start to yellow, cease routine watering immediately and keep the medium almost completely dry.
Failure to bloom
Catasetum integerrimum requires a pronounced cool, dry winter rest — 6–8 weeks with temperatures around 15–18°C at night and minimal water. Skipping this rest period reliably prevents flowering the following season.
Mealybugs and scale insects
The soft new pseudobulbs attract mealybugs, especially where air circulation is poor. Inspect regularly; treat early infestations with isopropyl alcohol on a swab or a diluted horticultural oil spray.
