Overview of Kiwi
Scientific Name: Actinidia deliciosa
Common Name: Kiwi, Chinese gooseberry
Origin: Kiwi is native to China but is also widely cultivated in New Zealand and other temperate regions around the world.
Benefits of Growing Kiwi in Your Garden
Kiwi is packed with vitamin C, vitamin K, vitamin E, and dietary fiber, making it a nutritious addition to your diet. Growing your own kiwi ensures access to fresh, pesticide-free fruit, and kiwi vines can provide lush greenery and attractive foliage in your garden.
Varieties of Kiwi
There are two main types of kiwi cultivated for fruit production:
Fuzzy Kiwi (Actinidic delicious): The most common type, known for its fuzzy brown skin and vibrant green flesh. Popular varieties include ‘Hayward’ and ‘Blake.’
Hardy Kiwi (Actinidia arguta): Smaller and smoother-skinned than fuzzy kiwi, with edible skin and a sweeter flavor. Varieties include ‘Arctic,’ ‘Issai,’ and ‘Ken’s Red.’
Climate and Soil Requirements
Kiwi vines thrive in temperate climates with cool winters and warm summers. They require full sun exposure and well-draining, fertile soil rich in organic matter. Kiwis prefer slightly acidic soil with a pH between 5.5 and 7.0. They are sensitive to waterlogged conditions and benefit from good air circulation.
Planting Kiwi
Planting kiwi requires careful consideration of site selection and soil preparation:
Choose a Location: Select a sunny, sheltered spot in your garden with support for the vigorous growth of kiwi vines. Kiwis can be grown against trellises, arbors, or pergolas, or they can be trained along wires.
Prepare the Soil: Kiwis prefer fertile, well-draining soil enriched with compost or aged manure. Before planting, amend the soil to improve fertility and drainage.
Planting Time: The best time to plant kiwi vines is in late winter to early spring, while the vines are dormant. This allows them to establish roots before the growing season begins.
Planting Method: Dig a hole large enough to accommodate the root ball of the kiwi vine. Place the vine in the hole, spreading out the roots carefully. Position the vine at the same depth it was growing in the nursery. Backfill the hole with soil, gently firming it around the roots. Water thoroughly after planting to settle the soil.
Care and Maintenance
Proper care and maintenance are crucial for healthy kiwi vines and a successful harvest:
Watering
Kiwi vines need regular watering, especially during dry periods and in the first few years after planting. Provide deep, thorough watering once a week, ensuring the soil around the roots remains consistently moist but not waterlogged. Mulching around the base of the vine helps retain moisture and suppress weeds.
Fertilization
Kiwi vines are heavy feeders and benefit from annual fertilization to support growth and fruit production. Apply a balanced fertilizer, such as 10-10-10, in early spring before new growth begins. Side-dress with compost or aged manure in mid-summer to provide additional nutrients.
Pruning
Pruning is essential for managing the vigorous growth of kiwi vines and promoting fruit production:
Young Vines: Prune young kiwi vines to establish a strong framework of main branches. Select 4-6 main canes and prune back lateral shoots to encourage growth along the main framework.
Mature Vines: Prune mature kiwi vines annually in late winter to early spring. Remove dead, damaged, or diseased wood. Thin out crowded areas and prune back excessive growth to maintain air circulation and light penetration.
Trellising and Support
Kiwi vines require support for their vigorous growth habit and heavy fruit load. Train vines along trellises, wires, or pergolas to support their weight and improve fruit quality. Prune vines to maintain a manageable size and shape within the trellis system.
Pest and Disease Management
Kiwi vines are susceptible to pests and diseases that can affect fruit production:
Pests
Scale Insects: These pests can infest kiwi vines, causing damage to leaves and fruit. Control with insecticidal soap or horticultural oil.
Spider Mites: These tiny pests can cause stippling and webbing on leaves. Spray vines with water to dislodge mites or use insecticidal soap.
Diseases
Powdery Mildew: This fungal disease appears as white powdery spots on leaves and shoots. Improve air circulation and apply fungicides preventatively.
Anthracnose: This fungal disease causes dark lesions on fruit and leaves. Remove and destroy infected plant material promptly.
Harvesting and Storage
Kiwi fruit is typically ready to harvest in late summer to early fall, depending on the variety and local climate. Here’s how to determine when kiwis are ready to pick:
Size and Color: Mature kiwi fruit is plump and reaches its full size. Fuzzy kiwis turn from green to brown, while hardy kiwis may change color slightly.
Firmness: Test ripeness by gently pressing on the fruit. Ripe kiwis yield slightly to pressure and feel firm but not hard.
Flavor: Taste a kiwi to ensure it is sweet and flavorful, as kiwis do not ripen further once picked.
Harvest kiwi fruit by cutting the stem with pruning shears. Handle kiwis carefully to avoid bruising, as they are delicate fruits. Kiwis can be stored in the refrigerator for up to several weeks or frozen for longer-term storage.
Recipes and Uses for Homegrown Kiwis
Homegrown kiwis are delicious fresh and can be used in a variety of culinary creations. Here are a few popular recipes:
Kiwi Smoothie: A refreshing drink made with kiwi, yogurt, and honey, blended until smooth.
Kiwi Salsa: A tangy salsa with diced kiwi, tomatoes, onions, cilantro, and lime juice, perfect for serving with grilled fish or tacos.
Kiwi Sorbet: A dairy-free frozen dessert made with pureed kiwi, sugar, and lemon juice, served chilled.
Kiwi Jam: A sweet spread made from kiwi, sugar, and pectin, ideal for spreading on toast or biscuits.
