Sunflower Seed Harvest: Paper Bag Method and Refrigerator Stratification

When and How to Collect

Wait until heads face down and backs turn brown. Seeds inside should be plump, not white.

1. Cut heads; store in paper bag in cool, dry place (basement).
2. After 2 months: shake bag—seeds dislodge easily.
3. Store seeds in Tupperware in refrigerator back (simulates winter dormancy).
4. Sow next spring after last frost.

Why This Works

• Paper bag allows slow drying without mold.
• Refrigerator cold period breaks dormancy for uniform spring germination.
• Protects seeds from birds/rodents during storage.

Simple, reliable method for homegrown sunflower seeds.
