Common Diseases
Powdery Mildew: Powdery mildew is a fungal infection that appears as white or gray spots on the plant's leaves. It can be caused by poor air circulation, high humidity, or overcrowding. To control powdery mildew, remove the affected leaves and improve the plant's growing conditions. You can also use fungicidal sprays to prevent further infection.
Botrytis Blight: Botrytis blight is a fungal disease that causes brown spots and wilting on the plant's leaves and stem. It is often caused by overwatering or poor drainage. To control botrytis blight, you can remove the affected parts of the plant or apply fungicidal sprays.
