Kuwa can be found all over the mountains of Japan where it is made into tea. The berries are not insipid or watery making the fruit perfect for fresh eating or jam. This species is self-fertile. Prefers a well-drained soil and can grow in part shade. The seed is easy to germinate. Just sprinkle it on the surface of the soil or lightly cover and keep moist. Germination will occur in two weeks. There is no dormancy required. This plant is hardy in zone 5 and one of the easiest mulberries to grow from seed and get to fruit in 3-6 years from seed -trees will be 3-5 ft. when they start to fruit. The flavor is truly lucious and worth eating fresh as they ripen in mid July here in southwestern Michigan.
Plant: 1/8 inch deep or less by sprinkling the seeds on the surface of the soil. Watch out for slugs. They seem to love the newly sprouted seedlings. No dormancy for this species and you can just plant after danger of frost if you are planting outside. For inside pot grown plants, use the same method but careful about over watering as the seedlings damp off easily in high organic soils. For storage of the seeds, just refrigerate or store dry. Do not freeze the seed. To unify the sprouting, you can add a moisture rententive peat to the seeds and store in a zip lock bag for 30 days in the refrigerator. This will cause the seeds to sprout more uniformly.
