Male Hardy Kiwi

Male hardy kiwi vines produce only male flowers, but those flowers have pollen suitable for cross pollinating female hardy kiwi flowers, such as those of the female cultivar 'Prolific.'  Even for varieties that are partially self-fertile, such as 'Issai,' cross pollination can significantly increase fruit set and ultimate yields. 

A ratio of one male vine for every four to eight female vines will work well for cross pollination. Male vines should be planted within 10-30 feet of female vines, though up to 50 feet can work. Hardy kiwi flowers are primarily pollinated by insects.

Male vines are vigorous but don't have to be allowed to mature to full size. Even a small flowering male vine will significantly increase cross pollination of female flowers nearby.

Male hardy kiwis are only appropriate for cross pollinating other hardy kiwi varieties (Actinidia arguta). Male hardy kiwi vines will not cross pollinate fuzzy kiwis or silver vines.

Male hardy kiwi vines grow similarly to grape vines, but are more vigorous. Provide a support structure like a fence, arbour or trellis.
