Growing directions
Hardy kiwi vines are dioecious — plant one male vine for every 6–8 female vines or choose a self-fertile cultivar such as 'Issai'. The vines can take 4–7 years to bear fruit but become very productive once established, requiring a pergola or heavy-gauge trellis rated to hold at least 200 lbs. Prune to a permanent framework of main arms and renewal spurs each late winter, cutting lateral shoots back to 2–4 buds. Harvest when smooth, grape-sized fruits yield slightly to pressure and taste sweet.
