Preventing Overwintering Diseases in Raised Beds

Spores do overwinter in soil even after plant removal. Late-season fix: spray copper/sulfur fungicide, cover bed with 3-mil black plastic for winter solarization. Sun + heat + fungicide kills spores.

Spring: amend with compost, aged manure, shredded leaves. Rotate crops 3-year cycle. Mulch at planting. Healthy soil biology suppresses pathogens naturally.
