Kiwi Trees, Plants and Vines: What You Need to Know to Grow

Kiwi trees, also known as kiwi plants and vines can be fruitful addition to any garden or orchard. Originally from China, these climbing vine trees have gained popularity worldwide for their delicious and nutritious fruit. Kiwi plants are known for their vigorous vine growth, attractive leaves, and ability to produce an abundance of flavorful fruits. In this overview, we will share everything you need to know about growing kiwi trees, from the different types available to the care and maintenance they require.

Types of Kiwi Trees - Fuzzy Kiwi vs Hardy Kiwi

There are two types of kiwi: fuzzy kiwi trees (Actinidia deliciosa) and hardy kiwi plants (Actinidia arguta). Fuzzy kiwi is the most common variety found in supermarkets, with its brown, fuzzy skin and brilliant green flesh. Hardy kiwi on the other hand, also known as kiwiberry, is smaller and has smooth, edible skin. While both types produce delicious fruits, fuzzy kiwi trees are generally larger and require more space to grow, making them better suited for larger gardens or orchards. Hardy kiwi plants, on the other hand, are more compact and can be grown in smaller spaces, such as backyard gardens.

Male Kiwi vs Female Kiwi

Unlike many other fruit trees, kiwi trees are dioecious, which means they have separate male and female plants. The female kiwi trees produce the delicious fruits we all enjoy, while the male kiwi trees are responsible for pollination. It is crucial to have at least one male kiwi tree for every 8-10 female kiwi trees to ensure proper pollination and fruit set if you are growing kiwi in an orchard. Male kiwi trees do not produce fruit themselves, but they play a vital role in the reproductive process. It is important to select the appropriate male cultivars that bloom at the same time as the female cultivars to ensure successful pollination and fruit production. So, remember, if you are growing kiwi in your garden or backyard, you need to plant two plants; one male and one female to grow any fruit.

Growing Kiwi Trees - Climate, Soil, and Sunlight Requirements

Kiwi trees thrive in temperate climates, with cool winters and warm summers. They are hardy in USDA zones 7-9 and require a chilling period during winter to break their dormancy. When selecting a site for your kiwi trees, choose an area that receives full sun to ensure optimal growth and fruit production. Kiwi trees prefer well-draining soil with a pH level between 5.5 and 7.5 as is the case with most gardening soil. Before planting, it is advisable to amend the soil with organic compost to improve drainage and fertility. Additionally, ensure that the site is protected from strong winds, as kiwi vines are prone to damage from excessive wind blow.

Planting and Caring for Kiwi Plants and Trees - Irrigation, Fertilization, and Pruning

Proper planting and care are essential for the success of your kiwi trees. When planting, dig a hole that is wide and deep enough to accommodate the root system of the tree. Place the kiwi plant or tree in the hole, ensuring that the bud union is at or slightly above ground level. Backfill the hole with soil, gently firming it around the roots. After planting, water the tree thoroughly and provide a layer of mulch around the base to conserve moisture and suppress weeds. Kiwi trees require regular irrigation, especially during the hot summer months, to ensure proper growth and fruit development. Fertilize the trees annually in early spring with a balanced fertilizer to provide essential nutrients.

Pruning is an integral part of kiwi tree care. It helps maintain the desired shape, control growth, and improve air circulation, which reduces the risk of disease. Prune your kiwi trees during winter when the plants are dormant, removing any dead, damaged, or crossing branches. Aim to create an open framework that allows sunlight to reach the inner parts of the vine. Additionally, prune back lateral branches to encourage the development of fruiting spurs. Regular pruning will help keep your kiwi trees healthy and productive.

Trellising Techniques for Kiwi Plants and Trees - Supporting the Climbing Vine

Kiwi trees are vigorous climbers that require support to grow properly and produce an abundant harvest. Trellising is an essential technique for managing kiwi vines and ensuring they have a sturdy structure to climb on. When choosing a trellis system for your kiwi trees, consider their size, growth habit, and the available space. A popular trellising method for kiwi trees is the pergola system, where the vines are trained along overhead wires supported by posts. Another option is the T-bar trellis system, which consists of horizontal wires attached to a central vertical post and yest another option is to support the vines using a Tomato Volcano.

Timing and Techniques for Harvesting Kiwi Fruits - When and How to Pick Them

Knowing when and how to harvest kiwi fruits is essential to enjoy them at their peak flavor and quality. Kiwi fruits are ready to be harvested when they reach their full size and firmness, but before they become overly soft. The exact timing may vary depending on the cultivar and growing conditions, but generally, kiwi fruits are harvested in late autumn or early winter. To harvest the fruits, gently twist them off the vine, leaving a short stem attached. Avoid pulling or tugging on the fruits, as this may damage the vines. Once harvested, kiwi fruits can be stored in a cool, dark place for several weeks or refrigerated to extend shelf life.

Key Takeaways for Successfully Growing Kiwi Trees

Growing kiwi trees can be a rewarding experience, providing you with an abundant supply of delicious and nutritious fruits. Remember to choose the right type of kiwi tree for your space and needs, with fuzzy kiwi being ideal for larger gardens and hardy kiwi for smaller spaces. Ensure you have both male and female kiwi trees for proper pollination and fruit set. Provide your kiwi trees with the right growing conditions, including a suitable climate, well-draining soil, and full sun exposure. Take care of your kiwi trees by providing regular irrigation, fertilization, and pruning. Finally, enjoy the fruits of your labor by harvesting the kiwi fruits at the right time in late fall or early winter.
