Gardeners who are fortunate to live in warm regions have the proper climate for growing persimmon trees. Persimmon trees grow into attractive ornamental trees that first produce flowers and then small fruits ranging in color from yellow to red. If you harvest persimmon seeds, harvest them in the autumn and give them a lengthy stratification (chilling) period before they will sprout and grow into new persimmon trees.
Harvest the seeds from the persimmon fruits in the late summer or early autumn. Place the seeds into the colander and rinse them well in cool water. Allow the seeds to drain well in the sink.
Place a double layer of paper towels onto the baking sheet. Spread the washed persimmon seeds onto the paper towels, making sure the seeds do not touch each other. Place the baking sheet in a warm and dry location for three days.
Fill the planting container with potting soil. Plant one persimmon seed in each planting container and cover the seed with ½-inch potting soil. Water the soil generously.
Place the container in the plastic bag and seal the bag. Place the container in the refrigerator and leave it there to stratify for three months. Once or twice per week, remove the container from the plastic bag and water the soil lightly.
Remove the container from the refrigerator after three months elapses. Place the container in a sunny windowsill if the outdoor temperatures are cold. If the outdoor temperatures are warm, place the container outside.
Keep the soil moist. The persimmon seed should germinate once you expose the seed to warmth after the stratification period. If the seed does not germinate, repeat Steps 4 and 5.
