Summary

Southern blight is a hot-weather fungal disease that attacks many ornamentals and some woody plants, often causing sudden wilting and death near the soil line. Explains how the fungus survives in soil and plant debris and how it can spread on water, tools, shoes, and containers. Describes what to look for during summer, including white fungal growth and small seed-like structures on stems and debris. Includes management steps such as sanitation, removing infected plants and nearby soil, improving airflow, adjusting soil conditions, and using fungicides when appropriate.
