Planting Persimmon Seeds: Cold Stratification and Seedling Care

Stratification Is Essential

Persimmon seeds require an extended cold period to break dormancy. After cleaning, store seeds in the refrigerator (not freezer) for at least 90 days in a sealed plastic bag with moist potting soil.

Sowing and Germination

In March, plant seeds ½ inch deep in individual pots of moist potting mix. Keep warm. Germination is often sporadic; if no sprouts appear after several months, return pots to the fridge for another 90 days. Some deciduous tree seeds need multiple warm/cold cycles.

Light and Hardening Off

Once seedlings emerge, provide strong light—40-watt shop lights are ideal; windowsills often produce leggy plants. After the last frost, move pots outdoors to a sheltered spot for 10 days to acclimate before planting in their permanent location.
