Harvesting Hardy Kiwi

Hardy kiwi has moderate water needs. Water regularly during the growing season, particularly from late spring through summer when the vine is flowering and setting fruit. Aim for deep watering once or twice a week in dry weather; the soil should remain consistently moist but never waterlogged. Reduce watering in autumn as growth slows, and water sparingly in winter unless conditions are exceptionally dry. Mulch helps retain moisture and suppress weeds—top up the layer each spring. Feed in March and April with a balanced general-purpose fertiliser (such as blood, fish and bone) or a potassium-rich feed to support flowering and fruiting. Scatter a handful around the base of each plant and water in well. Avoid high-nitrogen feeds after late spring, as these promote soft, leafy growth at the expense of fruit and can reduce winter hardiness. Hardy kiwi is fully hardy in zones 4a–8b and needs no special winter protection in temperate Europe. However, late spring frosts can damage emerging shoots and flowers, so avoid planting in frost pockets if possible. If frost is forecast during flowering, drape fleece over young vines overnight. Pests are generally few. Watch for aphids on soft new growth in spring; a strong jet of water or an insecticidal soap usually suffices. Cats are sometimes attracted to the scent of young plants and may damage stems by rubbing—protect with netting or a wire guard if necessary. Fungal issues are rare if air circulation is good, but remove any mildewed or spotted leaves promptly. Harvest the smooth-skinned fruit in September or October when slightly soft to the touch; they ripen further indoors.
