Humid, still conditions are the perfect breeding ground for botrytis, a fungus that affects plant tissue. It is most prevalent in spring and autumn and particularly affects oft and unhealthy growth. Affected areas are covered with grey clusters of spores. Defoliation, and even plant death, can follow. Spores are easily spread through the air and via splashing water so it is easily spread and can become difficult to manage. To reduce the risk of infection allow good air circulation round plants to reduce humidity. Remove any dead or dying plant material and avoid excessive watering. Treatment is with copper-based fungicide.
