Brassia 'Rex' problems — and how to fix them
Brassia 'Rex' (Brassia Rex) 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.
Few or no flowers
Most often too little light. Brassia Rex is shy to bloom in dim conditions; brighten its position and ensure mature pseudobulbs are well grown before expecting spikes.
Root rot from a tired mix
Old, broken-down bark stays wet and suffocates roots. Repot into fresh coarse medium every 2 years and water only on a dry-down cycle.
Pleated new growth
Concertina-folded leaves indicate water or humidity shortfall during growth. Keep watering and humidity consistent as new leaves expand.
Scale and mealybugs
Hide among bulbs and leaf bases as brown bumps or cottony masses. Wipe off and treat with horticultural oil or insecticidal soap, repeating to catch crawlers.
