Freezing Seeds Doesn't Improve Germination

Stratification vs. Freezing

Freezing seeds for a week provides no benefit. Some species require stratification—moist storage at 40°F for 8 weeks—but a home freezer is too cold and dry.

What Actually Helps Hard-Coated Seeds

Soak seeds in lukewarm water for 24 hours before planting. This works well for okra, beets, sweet peas, and other hard-coated varieties.
