🌱 Common Causes
Brown spots on your Crape Myrtle 'Catawba' can stem from several issues. Understanding these causes is crucial for effective treatment.
Fungal Diseases
Fungal infections are a primary culprit behind leaf spots. Common fungi include Cercospora and Alternaria, which thrive in humid conditions and can quickly spread if not addressed.
Environmental Stress
Environmental factors play a significant role in leaf health. Drought, excessive moisture, and temperature fluctuations can stress your plant, leading to brown spots as it struggles to adapt.
Nutrient Deficiencies
