Troubleshooting
Olive Porroglossum problems — and how to fix them
Olive Porroglossum (Porroglossum olivaceum) 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.
Bud blast
Flower buds abort before opening when humidity drops below about 70%, when temperatures spike above 22°C, or during sudden environmental changes. Maintain stable cool, humid conditions and avoid moving the plant once buds appear.
Root rot from poor drainage
Despite needing constant moisture, the roots rot rapidly if water sits around them rather than draining through freely. Use a very open medium, ventilated pots, or mounted culture, and water early in the day.
Botrytis (grey mould)
High humidity combined with poor airflow creates ideal conditions for Botrytis cinerea, which causes fluffy grey patches on leaves and flowers. Counter it with small circulation fans running continuously and removing any dead or damaged tissue promptly.
