Troubleshooting
Autumn Laelia problems — and how to fix them
Autumn Laelia (Laelia autumnalis) 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.
Buds blasting before opening
Sudden changes in temperature, draughts, or low humidity during bud development cause bud blast. Once spikes emerge, maintain stable conditions, avoid moving the plant, and keep humidity above 55% until flowers are fully open.
Lack of dry rest causes bloom failure
Consistent year-round watering prevents pseudobulb maturation and spike initiation. Withhold water significantly from July through September every year without exception, regardless of how the plant looks.
Mealybugs
White cottony masses in pseudobulb crevices and at the base of leaves signal mealybugs. Remove manually with isopropyl alcohol and follow up with repeated neem oil treatments. Isolate affected plants to prevent spread.
