9. Botrytis Blight (Gray Mold)
Ever seen a gray fuzz invading your plant’s flowers? That’s Botrytis blight, also known as gray mold.
This disease thrives in cool, damp conditions, attacking flowers, leaves, and stems. Proper spacing and airflow can deter its spread.
I’ve heard that removing affected parts immediately and using fungicides can be crucial. It’s like playing detective, tracking down the mold before it takes over. Your garden’s beauty deserves this level of care.
