Dogwood Seed Germination: Scarification vs. Cold Stratification

Breaking Dogwood Seed Dormancy Without Animal Digestion

While dogwood seeds naturally germinate after passing through bird digestive tracts (which scarifies the hard seed coat), artificial methods work reliably.

Cold Stratification Method (Recommended)

1. Place seeds in damp paper towel inside sealed bag
2. Refrigerate for 3 months
3. Plant 1 inch deep in pots
4. Provide 75°F and 40-watt shop lights
5. Germination in 2-3 weeks

Outdoor Alternative

Sow seeds in pots outdoors in fall. Keep watered through winter. Natural freeze-thaw cycles provide stratification. Seedlings emerge in spring after last frost—already hardened off.

Scarification Option

Mechanically nick seed coat with a knife or file to mimic digestive wear. Then stratify as above. This can speed germination but isn't necessary if cold stratification is done properly.
