Stratifying Plum Seeds for Germination

Store-bought plum seeds are hybrid—seedlings variable, 5–7 years to fruit. But stratification works the same.

Methods

Outdoor: Plant 1 inch deep in pot; leave outside winter, water regularly.
Fridge: Wrap in damp towel, bag, refrigerate 60–90 days. Then pot in warmth (70°F).

Process = vernalization/stratification. Transplant after second true leaves.
