Additional Tips for Growing Disease-Resistant Perennials

To maximize the health and longevity of your perennials, ensure proper planting practices. Use well-draining soil, avoid overwatering, and provide adequate spacing for air circulation. Regularly remove dead or diseased foliage to prevent the spread of infections.
