How do you prevent disease in chrysanthemums?

Our Advice:

Chrysanthemums can be susceptible to diseases such as powdery mildew, grey mold, and bacterial leaf spot. To prevent disease, start by choosing disease-resistant cultivars and planting them in well-draining soil in a sunny location with good air circulation. Avoid overwatering or watering the foliage, which can promote disease. Remove any diseased leaves or flowers immediately and dispose of them in the bin, not the compost pile. It's also a good idea to sterilize pruning tools and pots before and after use to prevent the spread of disease.
