Common Garden Diseases: Identification and Organic Management

Even well-tended gardens face diseases. Recognizing and managing them organically protects your harvest.

Major Diseases

Mosaic Virus

Highly contagious, incurable. Symptoms: stunted growth, curling leaves. Prevention: buy resistant varieties, use homemade insect sprays to deter virus-carrying insects. Destroy infected plants immediately.

Wilts

Identified by wilting lower leaves with yellow blotches. Cucumber beetles transmit it. Plant resistant varieties; monitor for beetles and other vectors.

Powdery Mildew

White/gray powdery coating on leaves, stems, flowers. Prevention: prune for air circulation, remove fallen leaves, maintain organic mulch. Treatment: baking soda spray (mixed with water) cures and prevents spread.

Clubroot

Fungus affecting cabbage, cauliflower, broccoli. Symptoms: swollen roots, wilting in sun. Prevention: resistant seeds, annual crop rotation.

Nutrient Management

After controlling pests, weeds, water, and diseases, ensure adequate nutrition via rich soil and compost. Heavy feeders like corn need compost every few weeks. Supplement with aged manure from nurseries or farms if compost underperforms.

Vigilance and organic practices keep gardens productive despite disease pressure.
