Wallis's Dragon Orchid problems — and how to fix them
Wallis's Dragon Orchid (Dracula wallisii) 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.
Failure to bloom without cool nights
Dracula wallisii requires consistent night temperatures below 13°C to initiate and sustain flowering. Without this, plants remain vegetative. A cool basement, cellar, or temperature-controlled greenhouse is necessary.
Sphagnum moss compaction and root rot
Long-fiber sphagnum breaks down over 1–2 years, compacting and holding too much moisture. Repot annually into fresh sphagnum to maintain aeration and prevent anaerobic root conditions.
Scale insects
Small brown scale insects can colonize pseudobulbs and leaf bases. Inspect regularly and treat early with rubbing alcohol on a cotton swab or with a horticultural oil spray.
