Preventing Tomato Blight with Crop Rotation and Solarization

Breaking the Blight Cycle in Upstate New York Gardens

Tomato blight persists in soil for up to 3 years. Black plastic "burning" in cool climates is ineffective.

Proven Strategies

Rotation: Move tomatoes to a new area for 3 years.
Containers: Grow in pots for 1-2 years to starve soil-borne pathogens.
Leaf Protection: Keep foliage dry—use greenhouses, cold frames, or drip irrigation.
Solarization: Cover infected beds with clear plastic for 3 months in hottest summer period.

Soil Building

After solarization, amend with compost, peat moss, and aged manure to restore beneficial biology.
