Botrytis Disease - Houseplants Disease and Control
Some links in this post may be affiliate links
Botrytis disease also called Black Mold is characterized by grey, fluffy mould which can cover all parts of the houseplant; leaves, stems, buds and flowers if the growing conditions are cool, humid and still (no air circulation). Begonia, Cyclamen, Gloxina and Saintpaulia are highly susceptible to this disease though it can affect all soft-leaved houseplants.
- Cut and destroy all affected parts of the plant, remove and replace mouldy soil with fresh soil, spray the plant with a systemic fungicide, reduce watering and misting and improve ventilation.
