What To Know
- This guide will walk you through the process of how to grow kiwi fruit in a greenhouse, ensuring you have the knowledge and skills to nurture your vines to a bountiful harvest.
- This is the classic kiwi fruit we’re all familiar with, featuring a brown, fuzzy skin and a tangy, slightly acidic flavor.

Growing kiwi fruit, with its vibrant green flesh and sweet-tart flavor, is a rewarding experience. But achieving success with this vine requires a specific set of conditions that can be challenging to meet outdoors. That’s where the greenhouse comes in. A greenhouse provides the controlled environment necessary to cultivate these delicious fruits, even in climates where they wouldn’t naturally thrive. This guide will walk you through the process of how to grow kiwi fruit in a greenhouse, ensuring you have the knowledge and skills to nurture your vines to a bountiful harvest.
Understanding Kiwi Fruit Varieties
Before embarking on your kiwi fruit journey, it’s essential to select the right variety. There are two main types of kiwi fruit:
- Hardy Kiwi (Actinidia arguta): This variety is more cold-tolerant and produces smaller, fuzzless fruits with a slightly sweeter flavor. They are also known as “arctic kiwi” or “baby kiwi.”
- Fuzzy Kiwi (Actinidia deliciosa): This is the classic kiwi fruit we’re all familiar with, featuring a brown, fuzzy skin and a tangy, slightly acidic flavor. They require warmer temperatures and are less cold-hardy.
The choice of variety will depend on your climate and personal preference. Hardy kiwis are a good option for cooler regions, while fuzzy kiwis thrive in warmer climates.
Planning Your Greenhouse Setup
Creating the ideal environment for your kiwi vines requires careful planning. Here are some key factors to consider:
Sunlight: Kiwi vines need at least six hours of direct sunlight daily. Ensure your greenhouse is positioned to receive ample sunlight, especially during the growing season.
Temperature: Kiwi vines prefer temperatures between 60°F and 80°F (15°C to 27°C). The greenhouse should be able to maintain these temperatures, particularly during the winter months in colder climates.
Humidity: Kiwi vines thrive in humid environments. Consider using a humidifier or misting system to maintain adequate humidity levels.
Air Circulation: Proper air circulation is crucial to prevent fungal diseases and ensure even growth. Install fans or vents to ensure good airflow within the greenhouse.
Soil: Kiwi vines prefer well-drained, fertile soil with a pH of 6.0 to 6.5. You can use a potting mix specifically designed for fruits or amend your existing soil with compost and other organic matter.
Planting and Training Your Kiwi Vines
Once your greenhouse is set up, it’s time to plant your kiwi vines.
Planting:
- Plant your kiwi vines in the spring after the last frost.
- Dig a hole twice the width and depth of the root ball.
- Amend the soil with compost or fertilizer.
- Carefully place the vine in the hole, ensuring the root ball is level with the ground.
- Backfill the hole and water thoroughly.
Training:
- Kiwi vines are vigorous growers and require support.
- You can use a trellis system, which creates vertical rows for the vines to climb.
- Install the trellis before planting, allowing space for the vines to grow.
- As the vines grow, train them along the trellis using twine or clips.
- Prune the vines regularly to maintain their shape and encourage fruit production.
Fertilizing and Watering
Regular fertilizing and watering are crucial for healthy kiwi vines.
Fertilizing:
- Apply a balanced fertilizer, such as 10-10-10, to the soil around the base of the vine in early spring.
- Repeat fertilization every 4-6 weeks during the growing season.
- Avoid over-fertilizing, which can lead to excessive foliage growth and reduced fruit production.
Watering:
- Keep the soil consistently moist but not waterlogged.
- Water deeply and infrequently, allowing the soil to dry slightly between waterings.
- During hot, dry periods, you may need to water more frequently.
Pollination and Fruit Production
Kiwi vines are dioecious, meaning they have separate male and female plants. For fruit production, you’ll need at least one male vine for every 8-10 female vines.
Pollination:
- If you have both male and female vines, pollination will occur naturally.
- Bees and other pollinators are essential for successful pollination.
- You can also hand-pollinate by collecting pollen from the male flowers and applying it to the female flowers.
Fruit Production:
- Kiwi fruit typically matures in late summer or early fall.
- The fruit will ripen on the vine and can be harvested when it turns a deep brown color.
- Store harvested kiwi fruit in a cool, dry place for up to two weeks.
Protecting Your Vines from Pests and Diseases
Kiwi vines are susceptible to various pests and diseases. Here are some common problems to watch for:
Pests:
- Aphids: These small insects can suck sap from the leaves and weaken the vine.
- Scale insects: These armored insects can cause damage to the leaves and stems.
- Mites: These tiny creatures can cause webbing and damage to the leaves.
Diseases:
- Powdery mildew: This fungal disease causes a white, powdery coating on the leaves.
- Botrytis blight: This fungal disease can cause brown spots on the leaves and fruit.
- Root rot: This fungal disease can damage the roots and cause wilting.
Prevention:
- Maintain good hygiene in the greenhouse by removing any infected leaves or fruit.
- Provide adequate air circulation to prevent fungal diseases.
- Monitor your vines regularly for signs of pests and diseases.
- Use appropriate pesticides or fungicides as needed.
The Final Chapter: Harvesting the Rewards
The moment you’ve been waiting for has arrived: harvest time!
- Kiwi fruit is typically ripe when the skin turns a deep brown color and feels slightly soft to the touch.
- Gently twist the fruit from the vine to harvest.
- Store the harvested fruit in a cool, dry place for up to two weeks.
What You Need to Know
Q: How long does it take for a kiwi vine to produce fruit?
A: It typically takes 3-5 years for a kiwi vine to start producing fruit.
Q: Can I grow kiwi fruit in a small greenhouse?
A: Yes, you can grow kiwi fruit in a small greenhouse, but you may need to choose a smaller variety like the hardy kiwi.
Q: How do I know if my kiwi vine is male or female?
A: The easiest way to tell is by looking at the flowers. Male flowers have a large number of stamens (the pollen-producing parts) and no pistil (the female reproductive part). Female flowers have a prominent pistil and fewer stamens.
Q: What are the benefits of growing kiwi fruit in a greenhouse?
A: Growing kiwi fruit in a greenhouse provides a controlled environment that protects the vines from harsh weather conditions, pests, and diseases. It also allows you to extend the growing season and produce fruit in areas where they wouldn’t naturally thrive.
Q: What are some tips for successful kiwi fruit cultivation in a greenhouse?
A: Choose the right variety for your climate, provide adequate sunlight and temperature, maintain good humidity and air circulation, fertilize and water regularly, and protect the vines from pests and diseases. With proper care and attention, you can enjoy a bountiful harvest of delicious kiwi fruit.
