Troubleshooting
Hirtz's Dragon Orchid problems — and how to fix them
Hirtz's Dragon Orchid (Dracula hirtzii) 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 plant collapse
Temperatures above 25°C even briefly cause leaf drop and rapid root system collapse. This species has zero heat tolerance; a dedicated cool-growing space (basement, cool greenhouse with cooling, or air-conditioned room) is a prerequisite.
Pendant spike blocked in standard pots
Inflorescences grow downward and must exit through the sides or bottom of the container. Growing in a standard closed pot results in spikes bending back on themselves and buds aborting. Slatted baskets or net pots are mandatory.
Botrytis fungal spotting
High humidity combined with stagnant air rapidly causes Botrytis grey mould on flowers and leaves. Maintain constant gentle air movement with a small fan and never allow water to sit in the crown or on open flowers.
