Botrytis Blight
Botrytis blight is a fungal disease that causes brown spots on leaves and stems of the plant. Infected areas will eventually turn gray and become covered with a grayish mold. To manage botrytis blight, remove all affected plant parts and dispose of them properly. Reduce humidity and improve air circulation around the plant to prevent further spread.
Crown Rot
Crown rot is caused by a soil-borne fungus that affects the crown and roots of the plant, causing them to turn brown and eventually rot. To manage this disease, avoid overwatering and make sure that the soil around the plant is well-draining. Remove all infected plant parts and disinfect pruning tools to prevent further spread of the fungus.
Downy Mildew
Downy mildew is a fungal disease that causes yellow, brown, or purple discoloration on the upper surface of the leaves, and a white or gray powdery growth on the undersides. To manage downy mildew, remove all infected plant parts, and dispose of them properly. Reduce humidity and improve air circulation around the plant to prevent further spread.
