Control Measures:

Implementing the following control measures can help prevent and manage botrytis blight in your winter garden:

Sanitation: Start by removing and destroying any infected plant material, including fallen leaves and debris. This reduces the chances of the disease spreading.

Air Circulation: Ensure proper air circulation around your plants by spacing them appropriately. This helps reduce humidity levels and inhibits the growth of the fungus.

Water Management: Avoid overwatering your plants, as excess moisture creates favorable conditions for botrytis blight. Water at the base of the plants to keep the foliage dry.

Pruning: Regularly prune and thin out dense foliage to improve air movement and sunlight penetration. This helps create an unfavorable environment for the fungus to thrive.

Organic Fungicides: Consider using organic fungicides labeled for botrytis blight control. Apply them according to the instructions provided, focusing on the affected areas.

Plant Selection: Choose disease-resistant plant varieties whenever possible. These varieties are less susceptible to botrytis blight and other common winter diseases.
