What Is Kiwifruit (Actinidia deliciosa)?

Plant Description

Kiwifruit, botanically classified as Actinidia deliciosa, belongs to the Actinidiaceae family. It is an attractive, deciduous vine that can reach heights of up to 30 feet (9 meters) or more. The plant features large, heart-shaped leaves with a fuzzy texture on the upper surface and a lighter, silver-green hue on the underside. Kiwifruit vines are dioecious, meaning individual plants are either male or female. Only the female plants bear fruit, while the male plants produce flowers essential for pollination. However, some newer varieties of kiwifruit are self-fertile, eliminating the need for separate male and female plants.

Fruit Characteristics

The edible fruit of the kiwifruit plant is a berry with a unique appearance. It has a rough, russet-brown skin, which is typically covered with short, stiff hairs. The flesh of the fruit is a vibrant, translucent green, speckled with tiny, black, edible seeds. The flavor of the fruit is often described as a harmonious blend of sweet, tangy, and slightly acidic notes. When ripe, the flesh becomes soft, and the taste becomes sweeter, making it a delightful addition to various culinary creations.



Kiwifruit has a versatile range of uses, from culinary applications to medicinal and cosmetic purposes. Below are some of the common uses of kiwifruit:

  • Culinary: Kiwifruit is an excellent addition to fruit salads, smoothies, and desserts. It can also be used in jams, jellies, and baked goods such as cakes and tarts.
  • Medicinal: Due to its high vitamin C content and other beneficial compounds, kiwifruit is often consumed for its immune-boosting and antioxidant properties. It is also known to aid in digestion and promote heart health.
  • Cosmetic: The vitamin C and E content in kiwifruit makes it a popular ingredient in skincare products. It is used in face masks, creams, and serums for its rejuvenating and protective effects on the skin.

Growing Conditions


Proper irrigation is crucial for the successful cultivation of kiwifruit. While kiwifruit plants require consistent moisture, they are susceptible to root rot if the soil is waterlogged. To prevent waterlogging, well-draining soil and irrigation systems should be employed. Young kiwifruit plants require more frequent watering, which can be gradually reduced as the plants mature.


Kiwifruit plants thrive in full sun to partial shade. Adequate sunlight is essential for promoting vigorous growth and fruit development. However, in regions with scorching summers, providing some protection from intense midday sun can prevent sunburn on the fruit and foliage.


Fertilization is an important aspect of kiwifruit cultivation. Prior to planting, a soil test should be conducted to determine the nutritional needs of the soil. Based on the results, a balanced fertilizer with a higher ratio of nitrogen can be applied to promote vegetative growth. Additionally, the use of organic amendments such as compost can improve the overall soil health and fertility.


Kiwifruit plants prefer well-draining, slightly acidic soil with a pH level ranging from 5.5 to 6.5. Soil that is rich in organic matter provides essential nutrients and encourages beneficial microbial activity. Heavy clay soil should be amended with organic matter to improve drainage, while sandy soil benefits from the addition of compost to enhance its water retention capacity.


Proper pruning is essential for maintaining the health and productivity of kiwifruit plants. Pruning helps in managing the size of the vine, promoting air circulation, and facilitating the penetration of sunlight into the canopy. The following are key considerations for pruning kiwifruit:

  • Training: Young kiwifruit plants should be trained onto a sturdy trellis to support their vigorous growth habit and facilitate easy access for maintenance activities.
  • Annual Pruning: Pruning is typically carried out during the dormant season to remove dead or diseased wood, shape the plant, and encourage the growth of fruiting wood.
  • Fruit Thinning: Thinning the fruit clusters promotes larger, healthier fruits and prevents overcrowding, which can lead to disease and uneven ripening.


Kiwifruit can be propagated through several methods, each offering distinct advantages and challenges. The following are common propagation techniques used for kiwifruit:

  • Seeds: While growing kiwifruit from seeds is possible, it may not produce fruit true to the parent plant and may take several years to bear fruit. However, this method is often used for breeding new cultivars.
  • Cuttings: Propagating kiwifruit from hardwood or softwood cuttings allows growers to maintain the desirable traits of a specific variety. Cuttings should be taken from healthy, disease-free plants during the appropriate season.
  • Grafting: Grafting is widely used to propagate kiwifruit, especially for commercial production. It allows for the precise replication of desired traits and ensures earlier fruiting compared to seed-grown plants.

Container Cultivation

If space is limited or if you simply prefer growing plants in containers, it is possible to cultivate kiwifruit in pots. However, it is essential to select a large container, such as a half whisky barrel, to accommodate the vigorous growth of the plant. Additionally, regular pruning and training are necessary to manage the size and shape of the vine. When grown in containers, kiwifruit plants may require more frequent watering and fertilization compared to those grown in the ground.


Kiwifruit, with its unique appearance, delightful flavor, and abundance of health benefits, has gained significant popularity worldwide. It is a staple in fruit salads and smoothies and is widely enjoyed as a standalone snack. Furthermore, the global demand for kiwifruit continues to rise due to increasing consumer awareness of its nutritional value and health benefits.

Common Diseases

Disease Diagnosis

Kiwifruit plants are susceptible to various diseases, including:

  • Crown Gall: Caused by the bacterium Agrobacterium tumefaciens, crown gall results in the formation of tumors or galls on the roots and lower stems of kiwifruit plants. Infected plants may exhibit stunted growth, wilting, and reduced vigor.
  • Bacterial Canker: This disease is characterized by the presence of small, sunken lesions on the trunk and can lead to dieback of the affected branches. It is caused by the bacterium Pseudomonas syringae.
  • Root Rot: Phytophthora spp. and Armillaria mellea are common pathogens responsible for root rot in kiwifruit plants. Symptoms include yellowing, wilting, and eventual collapse of the plant.

Proper disease diagnosis is essential for effective disease management. Laboratory analysis or consultation with a plant pathologist may be required to accurately identify the causal agent of the disease.

Common Pests


Aphids are small, soft-bodied insects that feed on the sap of kiwifruit plants, often clustering on the undersides of leaves and tender shoots. They can cause stunted growth, distortion of new growth, and the development of sticky honeydew that promotes the growth of sooty mold.

Spider Mites

Spider mites are common pests of kiwifruit plants, especially in hot, dry conditions. They cause stippling and discoloration of the leaves, leading to reduced photosynthetic activity. Severe infestations can cause leaf drop and a decline in overall plant health.


Thrips are tiny, slender insects that feed on the leaves and flowers of kiwifruit plants. They cause silvering or bronzing of the foliage and can transmit certain plant viruses. Infested flowers may fail to develop properly, leading to reduced fruit set.

Botanist’s Tips

1. Soil Preparation: Prior to planting kiwifruit, ensure that the soil is well-draining and has a slightly acidic pH. Conduct a soil test to determine its nutrient levels and make any necessary amendments.

2. Trellising: Construct a sturdy trellis to support the vigorous growth of kiwifruit vines. Proper trellising facilitates maintenance activities such as pruning, harvesting, and pest management.

3. Pollination: For kiwifruit varieties that require cross-pollination, ensure that male and female plants are planted in proximity to facilitate efficient pollination and fruit set.

Fun Facts

  • Kiwifruit is known for providing more vitamin C than an equivalent amount of oranges. This high vitamin C content contributes to the fruit’s immune-boosting properties.
  • New Zealand and Italy are among the leading producers of kiwifruit globally, with Hayward (or green-fleshed) kiwifruit being the most commonly cultivated variety.
  • The furry brown exterior of kiwifruit is not actually edible, but the skin is rich in fiber and can be consumed after thorough washing or removed if preferred.
