Why Persimmon Seeds Need Cold Stratification to Germinate

Dormancy Requirement

Persimmon seeds require an extended cold period (90+ days at 40°F/4°C or below) to break dormancy. Without it, seeds won't swell or sprout.

Outdoor: Plant in pots, leave outside all winter, keep watered.
Refrigerator: Seal potted seeds in a plastic bag; refrigerate 90 days. Then warm to 70°F. If no germination, repeat cold cycle.

Many deciduous tree seeds need multiple warm/cold cycles. Don't give up too soon.
