What are the common diseases or pests that affect azaleas?

Azaleas can be affected by several common diseases and pests, which can impact their health and overall appearance. One prevalent disease is phytophthora root rot, which thrives in overly wet soil and can lead to wilting, yellowing leaves, and stunted growth. To prevent this, it is essential to ensure proper drainage and avoid overwatering. Another common issue is powdery mildew, a fungal disease that manifests as white, powdery spots on the leaves. Adequate air circulation and proper spacing between plants can help reduce the likelihood of this disease. In addition to diseases, azaleas are susceptible to various pests. Aphids are tiny insects that can cluster on young leaves and stems, causing curling and discoloration. Regularly inspecting plants and using insecticidal soap or neem oil can effectively manage these pests. Another significant pest is the lace bug, which feeds on the undersides of leaves, causing a speckled appearance. Monitoring for these pests and treating infestations promptly can minimize damage. Spider mites may also pose a threat to azaleas. These minute pests can cause stippling and yellowing of leaves. Maintaining humidity levels and ensuring healthy plant conditions can help deter their presence.
