Troubleshooting
White Laelia problems — and how to fix them
White Laelia (Laelia albida) 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.
No flowers produced
Failure to bloom is almost always due to insufficient light, skipped summer dry rest, or lack of cool autumn nights. Ensure temperatures drop below 13°C at night in September–October and that watering was reduced through summer.
Shrivelled pseudobulbs
Mild seasonal shrivelling during the summer rest is normal and expected. Persistent or extreme shrivelling indicates root loss. Check roots; if damaged, repot into fresh coarse bark and resume careful watering.
Fungal spotting on leaves
High humidity without air circulation encourages Cercospora or Botrytis leaf spots. Increase airflow, avoid wetting foliage late in the day, and treat with a copper-based fungicide if lesions spread.
