Are Kiwi Plants Trees or Vines?

Kiwi is a unique fruit that has a distinct green flesh and a fuzzy brown exterior. This fruit is native to China but is now widely cultivated in countries like New Zealand, Italy, and Chile, among others. One question that often arises among curious individuals is whether kiwi plants are trees or vines.

The Nature of Kiwi Plants

Kiwi plants (Actinidia deliciosa) are woody perennial plants that belong to the Actinidiaceae family. These plants can grow to a height of 4 to 6 meters and have a lifespan of about 50 years. Kiwi plants have thick stems that can have a diameter of up to 20 cm, and these stems grow to support the leaves and the fruit.

Kiwi plants are not considered trees because of their stem structure. Though they have a woody stem, the stem is not strong enough to support the entire plant. Additionally, kiwi plants do not have a single trunk, which is a defining feature of trees. Instead, kiwi plants have several branches that grow from the ground level, and these branches can grow up to 20 meters in length.

On the other hand, kiwi plants are often considered vines because of their climbing habit. Kiwi plants climb by coiling around any available support, such as trees, trellises, or fences. The vines of kiwi plants have a lifespan of about 7 years, and they produce the fruit from the second year onwards.

Kiwi Plant Cultivation

Kiwi plants are generally propagated by grafting or cuttings. The plants are best grown in well-drained soils with a pH range of 5.5 to 6.5. These plants require ample sunlight and can tolerate temperatures ranging from -25°C to 40°C.

Like most fruit crops, kiwi plants require pruning to improve fruit quality and to facilitate easy harvesting. During pruning, the main stem of the plant is cut back to a height of about 1 meter above the ground, and the side branches are pruned to leave 3 to 4 buds. This helps to promote the growth of new branches and increases the fruiting surface area.

Kiwi Fruit Production and Harvesting

Kiwi plants bear fruit in the late summer or early autumn, depending on the variety and location. The fruit of kiwi plants is oval-shaped and has a green juicy flesh surrounded by a brown fuzzy skin. The fruit is rich in vitamins, minerals, and antioxidants and is commonly consumed raw or used in salads, desserts, smoothies, and other dishes.

Kiwi fruit is generally harvested by hand once it ripens. The fruit is ripe when it becomes soft to the touch and has a sweet aroma. The fruit is then graded according to size and quality and packed for transport to the market.

Conclusion

In conclusion, kiwi plants are not considered trees but rather woody perennial plants that grow into vines. These plants require ample support for their stems and can climb to a height of up to 20 meters. The fruit of kiwi plants is a delicious and nutritious fruit that has become popular worldwide.
