Organic Control of Nematodes and Mold in Garden Soil

Nematodes and fungal molds persist in soil. Best organic approach: fallow rotation and solarization.

One-Year Fallow

1. Till soil; plant nothing for 12 months.
2. Solarize with clear plastic 4–6 weeks in hot sun.
3. Apply beneficial nematodes (Steinernema) if available.

If Must Replant Sooner

• Till and treat with copper fungicide 3x at 2-week intervals.
• Plant resistant varieties (marked VFN).
• Add compost to boost beneficial microbes.

Prevention: rotate crops, avoid overhead watering, compost well.
