Roezl's Dragon Orchid problems — and how to fix them
Roezl's Dragon Orchid (Dracula roezlii) 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.
Heat stress and bud blast
Temperatures consistently above 25°C cause rapid leaf drop, root collapse, and flower bud abortion. A cool basement, air-conditioned greenhouse, or terrarium with a chiller is essential in warm climates. Night temperatures must drop to 12–15°C.
Crown and root rot
High humidity in stagnant air breeds Botrytis and Fusarium. Run a small fan continuously and ensure water does not pool in the crown. Treat early fungal spotting immediately with a copper-based fungicide.
Failed flowering due to dry air
Humidity below 60% prevents buds from developing fully; they shrivel and drop. Monitor humidity closely and increase misting frequency before spikes emerge, typically autumn through spring.
