Japanese Persimmon Seed Germination

Japanese persimmon (Diospyros kaki Linn) originated in the mountains of Asia. It grows wild at 8000 feet in China and above 3500 feet in Indonesia. Despite its high-altitude beginnings, the tree has adapted well to sea-level culture. Japanese persimmon seeds arrived in the United States from Japan in 1856. Trees planted in southern California, southeastern Virginia, northern Florida, Arizona, Texas, and other warm states have performed best. Japanese persimmons started from seeds are often used as rootstock.

Instructions

    • 1

      Loosen the ground to a depth of 6 inches with a pickax and shovel. Remove rocks, weeds and grass from the site.

    • 2

      Spread a 2-inch layer of manure or other organic soil amendment over the seedbed. Incorporate the matter 6 inches deep with a shovel. Rake the area to make a smooth bed.

    • 3

      Dig a furrow with a hoe or by dragging the tip of your shovel's handle. Make the trench twice as deep as the Japanese persimmon seeds are wide. Separate multiple rows by 3 feet.

    • 4

      Sow the persimmon seeds 1 foot apart. Fill the furrows with topsoil.

    • 5

      Lay a soaker hose by the seeds, and irrigate the soil to a depth of 3 to 4 inches. Keep the seedbed moist to promote germination. Let the seedlings develop an entire growing season before using them as rootstock.
