Q.how to germinate persimmon seeds
As you know, it is hard to germinate the persimmon seed. How best to do this?
Harvest a fresh Persimmon and remove the seeds from the fruit in late summer or early fall.
Add the seeds to a container of dampened peat moss and miss the seeds into the peat.
Put this seed and peat mixture into a sealed baggy and remove all the air.
Store the bag in the refrigerator for 60 to 90 days.
Remove the seeds and place one seed in small starter pots with potting mix, about 1" deep.
Keep the soil moist in a warm, sunny location.
Cover the pots with plastic and remove when the seeds have germinated.
Germination can take up to 14 days.
Germination rates may be only 50%.
Continue to water the seedlings when the soil has dried slightly and give them full sun.
