Troubleshooting
Disa uniflora problems — and how to fix them
Disa uniflora (Disa uniflora) 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.
Salt/mineral burn
Tap water or fertiliser salts blacken root tips and leaf margins. Use only rainwater, distilled or RO water and flush the medium frequently.
Heat stress
Roots above ~21°C trigger collapse and rot. Keep roots cool with cool water, shade and airflow through summer.
Crown and root rot
Warm, stagnant, waterlogged conditions cause Pythium and fusarium rots. Provide constant air movement and fresh, acidic, low-nutrient media.
Drying out
Even a brief dry-out can kill plants; the medium must stay permanently moist, ideally with the pot standing in shallow pure water.
