Actinidia arguta 'Hardy Male'Deciduous flowering vine used to pollinate all kiwi vines, both the hardy types and the fuzzy types (Act. deliciosa). We recommend 1 male for every 8 female vines. Plant on fence, trellis, arbor, etc. to provide structure. Hardy kiwi is a very vigorous vine that needs lots of room to roam. Plant in full sun, give good drainage and average water. Fertilize with all purpose the first few years, after that there won't be a need. USDA zones 4-10 in cold hardiness.
