Pollination Information for Issai Hardy Kiwi (Actinidia arguta 'Issai')

The Issai Hardy Kiwi is a self-fertile variety of Actinidia arguta, meaning it can produce fruit without requiring a separate male pollinator plant. However, having a male pollinator nearby can improve the quality and quantity of fruit produced.

Pollination Requirements:

• Self-fertile: Issai Hardy Kiwi is capable of self-pollination and setting fruit without a separate male plant.
• Enhanced Pollination: While self-fertile, having a male pollinator plant nearby can enhance pollination and increase fruit production.
• Male Pollinator: It is recommended to plant a male pollinator, such as Actinidia arguta 'Ken's Red' or Actinidia arguta 'Michigan State', near the Issai Hardy Kiwi for optimal fruiting.
• Pollination Method: Issai Hardy Kiwi is primarily pollinated by bees, but other pollinators like butterflies and hummingbirds may also contribute to the process.

Pollination Tips:

• Planting Distance: When planting a male pollinator, make sure it is within 50 feet of the Issai Hardy Kiwi to ensure effective pollination.
• Blooming Period: Issai Hardy Kiwi flowers in late spring to early summer. Ensure that the male pollinator blooms around the same time to maximize pollination success.
• Attracting Pollinators: To attract more pollinators, consider planting flowers or flowering herbs nearby. Providing a water source like a shallow birdbath can also help attract pollinators to the area.
• Protecting Pollinators: Avoid using pesticides and insecticides during the blooming period to protect pollinators and promote successful pollination.

Following these pollination tips will help ensure quality fruit production from your Issai Hardy Kiwi plant. Enjoy the delicious and nutritious rewards of your own homegrown kiwis!
