botrytis on Begonia Rex Escargot
Quick answer
If your Begonia Rex Escargot has botrytis, the most likely cause is: Begonia rex (the parent species of the 'Escargot' cultivar) develops fluffy grey mould on the leaves and stems when botrytis fungal disease is encouraged by excessive watering and humidity around the soft, moisture-loving rhizomatous foliage that the cultivar inherits from Begonia rex in the tropical rain forests of Assam.
Start here:
- 1. Spray the plant with benomyl to suppress the botrytis fungal infection on the leaves and stems of the Begonia rex 'Escargot' foliage.
- 2. Allow the compost to dry out and then resume watering as in ideal conditions, keeping the surface of the compost dry between waterings and never leaving the pot standing in water.
