Are coneflower immune to pests and diseases?
Coneflower is not very prone to pests and diseases and therefore, they are a safe bet in the garden. Nevertheless, they are sometimes susceptible to aphids, Japanese beetles or powdery mildew when it is humid. The fungal issues are minimized through proper spacing and good air circulation. Water should never be sprayed on as it causes leaf diseases. In case of the emergence of pests, it is frequently good to resort to the use of natural products such as insecticidal soap or neem oil. Healthy soil and exposure to sunlight ensure that plants are healthy and are well positioned to counter possible challenges.
