Yes, hardy kiwi seeds generally benefit from cold stratification before planting because they can have natural dormancy. A period of moist chilling can help improve germination. Follow the seed supplier's recommended preparation method and keep the growing medium moist during germination.
Issai kiwi plants grown from seeds can take several years to reach flowering and fruiting maturity. Seed-grown plants may also differ from the named Issai cultivar in fruit characteristics, growth habit, and pollination requirements. Plants grown from established named cultivars generally provide more predictable results than seedlings.
The named Issai hardy kiwi cultivar is commonly described as self-fertile, meaning it can produce fruit without a separate male pollinator. However, plants grown from Issai seeds may not retain the same characteristics as the parent cultivar. Confirm the plant's identity before relying on self-fertility.
