Common Pests & Diseases

• Leaf spot: This fungal disease can cause brown spots on the leaves, leading to defoliation. Remove infected leaves and avoid overhead watering.
• Powdery mildew: This fungal disease can cause a white powdery coating on the leaves, leading to stunted growth. It can be controlled with fungicides or by improving air circulation around the plants.
