Growing Hardy Kiwi: A Guide for Cool Climates
Introduction
Do you love the sweet and tangy flavor of kiwi fruit, but think you can’t grow them in your chilly climate? Think again! Newer varieties of hardy kiwi have made it possible to enjoy these delicious and nutritious fruits even in cooler regions.
What is Hardy Kiwi?
Hardy kiwi, also known as Actinidia arguta, is a type of kiwi that is native to Asia. Unlike the fuzzy brown kiwi you find in grocery stores, hardy kiwi are smaller, about the size of a large grape, and often have a rosy hue. They have tender, edible skin and are packed with Vitamin C and other nutrients.
Growing Hardy Kiwi
Growing hardy kiwi is not as difficult as you might think. Here are some tips to help you get started:
- Choose the right variety: There are several varieties of hardy kiwi available, so it’s important to choose one that is well-suited to your climate. Some popular varieties for cool climates include ‘Issai’, ‘Geneva’, and ‘Anna’.
- Plant in well-drained soil: Hardy kiwi prefer loamy soil that drains well. Avoid planting in areas that are prone to waterlogging.
- Provide support: Hardy kiwi vines are vigorous growers and can reach heights of over 20 feet. They need strong trellising to support their growth, both vertically and horizontally.
- Plant both male and female plants: Hardy kiwi are dioecious, meaning there are separate male and female plants. You will need to plant at least one male plant for every six female plants in order to get fruit.
- Be patient: Hardy kiwi plants can take several years to mature and bear fruit. Don’t be discouraged if you don’t see fruit right away.
Pruning Kiwi Plants
Pruning is essential for keeping your hardy kiwi plants healthy and productive.
- Dormant season pruning: Prune your hardy kiwi plants in late winter or early spring, before new growth begins. This will help to remove any dead or diseased wood and encourage the plant to grow in the desired direction.
- Summer pruning: Hardy kiwi vines also need frequent pruning throughout the summer. Cut back the terminal growth to four to six leaves beyond the last flower. Also, remove any shoots that may appear on the older wood and trunk, as well as any entangled shoots.
Caring for Hardy Kiwi Plants
Once your hardy kiwi plants are established, they are relatively easy to care for.
- Fertilize: Fertilize your hardy kiwi plants in the spring following the first planting. Use a balanced fertilizer, such as 10-10-10, and apply it at a rate of two ounces per plant. You can increase the amount of fertilizer by two ounces each year, but do not exceed eight ounces per plant.
- Water: Water your hardy kiwi plants regularly, especially during hot and dry weather. Avoid overwatering, as kiwi plants do not like wet feet.
- Mulch: Mulch around your hardy kiwi plants to help retain moisture, suppress weeds, and regulate soil temperature.
- Protect from pests and diseases: Hardy kiwi plants can be susceptible to certain pests and diseases, such as spider mites, leafrollers, thrips, and Japanese beetles. Be sure to inspect your plants regularly and treat any problems promptly.
Harvesting Kiwi
Hardy kiwi fruit is typically ready to harvest in late summer or early fall. The fruit should be firm to the touch and have a slight give when pressed. To harvest, simply cut the fruit from the vine with a sharp knife.
Conclusion
Growing hardy kiwi in cool climates is a rewarding experience. With a little patience and care, you can enjoy the delicious and nutritious fruits of these amazing plants for years to come.
