Hi- your Isaia is a female Actinidia arguta. It is somewhat self-fruitful but will produce more fruit if you plant a male Actinidia arguta. You would need to know exactly what species of hardy kiwi you bought and whether or not it is male. There are many online sources of male Actinidia arguta. Plant it within 30 ft. of your Isaia for best cross-pollination by insects.
