Kiwi fruit, once considered an exotic rarity, is now a common sight in grocery stores and often added to smoothies for its vibrant flavor and high vitamin C content. But have you ever wondered about the origins of this small, fuzzy fruit or how to grow it yourself? Here’s a detailed guide to growing kiwi fruit, whether you’re in a warm climate or a more temperate zone.
A Brief History of Kiwi Fruit
Kiwi fruit, originally known as the Chinese gooseberry, gained its “kiwi” name from New Zealanders, who dominated its cultivation in the 20th century. The fruit became synonymous with New Zealand and later spread worldwide. Once rare and expensive, kiwi fruit is now affordable and available year-round, thanks to increased production and global distribution.
Growing Kiwi Fruit at Home
Kiwi fruit vines thrive in warm, sunny climates. Originating from East Asia, these plants require consistent warmth to produce fruit. In temperate climates, you can still grow kiwi by planting them against a south-facing wall, where they can grow up to 10 meters (30 feet) tall. A warm wall offers protection against early spring frosts, ensuring that tender shoots aren’t damaged.
While kiwi vines can tolerate some shade, they won’t bear fruit unless given plenty of sunlight. The vines themselves are quite ornamental, with heart-shaped leaves, red stems, and fragrant flowers. To support their vigorous growth, sturdy supports are essential. Install horizontal wires along a wall or fence, spaced about 45 cm (18 inches) apart. A pergola or trellis can also work, as long as it’s strong enough to handle the weight of the vines.
Pollination and Varieties
Kiwi vines are dioecious, meaning male and female flowers grow on separate plants. To produce fruit, you’ll need one male plant for every six females. ‘Hayward’ is a popular female variety, while ‘Tomuri’ is a good male counterpart. However, if space is limited, consider planting self-fertile varieties like ‘Jenny’, which only require one plant to produce fruit. While one plant can be sufficient, pollination is generally better with two or more.
Kiwi vines prefer nutrient-rich, well-draining soil. If you’re planting near a wall, position the vines about a foot away from the base to avoid a rain shadow. Space the plants about 3 meters (10 feet) apart to allow for proper growth and pollination.
Pruning Kiwi Fruit Vines
Kiwi vines are fast-growing and need regular pruning to stay productive and manageable. You can choose to train them into a formal espalier shape or, more simply, prune the oldest stems each winter after the fruiting season. Kiwi vines produce fruit on side shoots of at least one-year-old canes, so ensure there’s a mix of old and new growth. Canes older than four years can be cut back to encourage fresh growth.
Pruning also helps with airflow and light penetration, which are vital for healthy vines. Don’t stress about identifying the exact age of each cane; just remove the thickest, oldest ones to make room for younger, more productive stems.
Harvesting Kiwi Fruit
Kiwi fruit typically ripen by mid-autumn, just before the first frost. They should be picked when they feel slightly soft and the skin is brown and fuzzy. If frost is imminent but the fruit isn’t quite ripe, harvest them early and allow them to ripen indoors in a cool, dry place. Once harvested, kiwi can last up to six weeks, so you can enjoy them for quite some time.
Care and Maintenance
Even though kiwi vines are hardy, they still need care. Apply a thick layer of mulch, such as well-rotted compost, in early spring to nourish the roots. Regular watering throughout the growing season is essential, especially during dry spells. This will help ensure a bountiful harvest of sweet, tangy kiwi fruit.
Conclusion
Growing kiwi fruit can be a rewarding experience, offering not only delicious fruit but also a beautiful and vigorous vine for your garden. With the right care, pruning, and patience, you can enjoy homegrown kiwi fruit year after year.
