A delight for home gardeners, kiwi vines are cold hardy, produce sweet and tangy fruits, and are sure to get attention when growing in the garden. Kiwi vines grow similar to grape vines—and can reach a height of 8' in the first year. When grown on a trellis, they make an excellent privacy screen. When buying kiwi vines for sale online, make sure they will grow in your hardiness zone or grow zone. Hardy kiwis grow best and produce the most fruit when grown in full sun to partial shade. At least one male kiwi plant is needed for every five female kiwis for proper pollination.
