Several diseases tend to appear in May, especially in warm and moist conditions. Some of the most common include:

  • Powdery Mildew: White, powdery spots on leaves and stems.

  • Leaf Spot Diseases: Circular spots with distinct borders on various plant leaves.

Signs to Look For

Early detection is key to managing plant diseases. Look for the following signs:
