Sudden Whole-Garden Collapse: Soilborne Disease and Solarization Solution

Introduction

Simultaneous death of multiple vegetable types after July 4th indicates soilborne disease.

Soilborne Disease Likely

Single-crop issues suggest pests; multi-crop = soil pathogen.

Need Agricultural Soil Test

Standard nutrient tests don't detect disease. Requires ag lab or top nursery.

Solarization: Fungicide + Black Plastic for 3 Months

Spray fungicide, cover with 3-mil black plastic for 3 months (now until spring, or March–June).

Copper Fungicide Spray for Remaining Plants

May help survivors, but soilborne diseases often irreversible once plants infected.

Conclusion

Solarize soil to eradicate pathogen; it's the only cure for recurring whole-garden collapse.
