Troubleshooting
Giant Dragon Orchid problems — and how to fix them
Giant Dragon Orchid (Dracula gigas) 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 collapse
Sustained temperatures above 24–25°C cause rapid wilting, leaf yellowing, and root death. In warm climates, grow in an air-conditioned space or a dedicated cool chamber. A chilled water tray under the basket can help reduce root-zone temperature on warm days.
Pendant spike blocked by pot
Growing Dracula in a solid-sided pot prevents the downward-emerging inflorescences from exiting the root zone, causing buds to abort underground. Always use open-sided slatted baskets or hanging baskets with gaps in the base.
Botrytis on flowers and buds
Cool, still, humid air promotes grey mould on delicate blooms. Increase air circulation with a fan directed past (not at) the plant, and avoid misting open flowers directly. Remove spent blooms promptly to reduce spore load.
