Identifying White Spots on Leafy Greens

White spots on backyard greens could signal several issues. Powdery mildew appears as dusty white patches, common in humid conditions. Spider mites leave tiny stippling and fine webbing—check leaf undersides with a magnifier. Viral infections cause mottling and distortion; they’re incurable.

Inspect closely: if spots wipe off, it’s likely mildew. Improve air circulation, water at soil level (not foliage), and apply copper-based fungicide or neem oil. If mites are present, spray insecticidal soap weekly. For viruses, remove and destroy plants. Always rotate crops and choose resistant varieties next season.
