Hardy kiwi

hardy-kiwi

Hardy kiwi (Actinidia arguta and A. kolomikta) is a vigorous, long-lived climbing vine producing grape-sized, smooth-skinned kiwifruit that can be eaten whole. A. kolomikta is the hardiest (suitable to colder zones and ripens earlier), while A. arguta is slightly less hardy but often more vigorous and productive. Plants need strong support (pergola, arbor, or T‑bar trellis) and careful training. Spring shoots and flower buds can be damaged by late frost; choose a site with good air drainage and shelter from cold winds. Cats may be attracted to young vines (similar to catnip effect) and can damage stems—use guards if needed.

Growing conditions

Light: Full sun to light shade; best fruiting in a warm, sheltered, sunny site.
Soil type: Deep, well-drained, humus-rich loam; evenly moist but not waterlogged. Mulch to keep roots cool.
Water requirement: Moderate and regular; keep evenly moist during establishment and fruit swell. Avoid waterlogging.
Nutrient requirement: Moderate; balanced organic feeding in spring, light top-up in early summer. Avoid heavy nitrogen late in season.
