Growing a hardy Kiwi trellis is a great idea to diversify and beautify your garden. Besides, healthy Kiwi vines give you tasty and good-quality fruits.
Aside from knowing how to grow Kiwi with the support of a trellis, you also need to learn about the proper methods to care for your Kiwi plants to help them thrive best.
Keep reading this article to understand how to plant these fruits and get other useful information.
What Is Hardy Kiwi?
The hardy Kiwi is the cousin of the fluffy brown fruit (Actinidia deliciosa). It may be known by various names, such as grape Kiwi, Arctic, Siberian, gooseberry, dessert, northern, or berry Kiwi.
You can see Kiwi berry trellis with delicious fruits or Kiwi berry products at most grocery stores. They are rich in vitamins C, B, antioxidants, and dietary fiber with great taste and sweetness.
How To Grow Hardy Kiwi Trellis?
The first step is to choose the right site with favorable conditions. Next, you must prepare the good hardy Kiwi and trellis for Kiwi to build a vine with a firm support structure.
Then, plant hardy Kiwi with proper fertilizing, irrigation, pruning, and training.
Select the Right Location for Planting
First, seek and choose the right location, allowing space to build a support Kiwi trellis or a plant near a fence or deck for their fruits to grow on vines.
Implementing this step in the first year of growing hardy Kiwi is important.
Also, consider choosing a well-drained and sunny site for planting. Hardy Kiwis need a lot of water to grow in their season, but they are unable to survive in soil with constant moisture.
Prepare The Hardy Kiwi
After selecting the proper location for planting, continue preparing the good-quality hardy Kiwis. Check the roots and remove overgrown or broken roots if you want to grow a bare-root plant.
When planting container plants, loosen their root system by taking the pot out.
Place the hardy Kiwi plant on the ground and use your palm to press hard against the root ball when it’s dense. Also, remove the roots from the root ball, and cut back if you see them too long.
Attach the Vine to the Support Structure
Attach a sturdy Kiwi vine to a fence, deck, or porch using garden twine or plastic wire.
If these supports are unavailable, make a trellis for your Kiwis by building a T-bar system using redwood posts of 4″ x 4″.
Secure these posts to cement holes prepared in the ground, place them in 5-gallon buckets, and use concrete to fill each one.
A four-foot board fixed to the erect post’s top will form a T-bar. Use screws to hold galvanized wire taut between these posts.
Choosing single or multiple wires distanced 12 inches apart is suitable. Besides, cut wires with the right lengths using cutters.
Planting Hardy Kiwi
Growing hardy Kiwi is the next step you must take. Regarding bare-rooted plants, identify a line of soil on the trunk through a color transformation from dark green to black or yellow.
Adjust this point above the soil surface around the holes for planting your plants. For potted plants, don’t leave the soil line in the pot lower than this point around the holes to avoid killing Kiwis.
Yet, ensure the plant’s roots are spread in the holes with the removed soil. Place the soil into the holes and cover around the plant’s roots.
Once completed, smooth out the soil, tamp it down, and give the plants plenty of water. In addition, spread organic fertilizer or compost on the soil to naturally nourish the plants and help them become healthy.
Fertilizing & Irrigation
The hardy Kiwifruits may consume a large nitrogen amount due to their fast growth rate and strong vitality.
After the first year of planting, in early Spring, an annual application of ½ lb of nitrogen can give your Kiwis healthy growth all Summer long. Yet, you should apply an organic nitrogen source.
All Kiwis feature spreading and shallow root systems and require plenty of watering during their season.
Applying mulch of 4 to 6 inches depth surrounding the plant (forming a circle of about 2-3 ft) may help retain moisture and prevent weed growth.
Besides, compost, hay, or straw are suitable for mulching. In warmer climates, a generous watering frequency of once a week is enough to avoid overwatering.
Prepare your plants for Winter weather by watering less in early Autumn.
Pruning & Training
After planting, support the Kiwis by tying them to a stake. Once their roots form and grow, they can produce vigorous shoots next to the plant base.
When these shoots grow approximately two feet long, tie the sturdiest ones to stakes and let them rise to the trellis top.
Tilt the other shoots back at this point so that they don’t conflict with the selected shoot.
Once the main bud touches the trellis or another support’s top, remove the other feeble shoots and leave the selected shoot as the main stem of the Kiwi fruit vine.
Once the main bud grows over the trellis top, prune the top to allow the upper ones to keep growing.
Encourage these buds to thrive along the available wires and structures of the trellis or Kiwi arbor, loosely tying them together.
These new buds will begin to form lateral cordons as the stainable structure for your hardy Kiwi.
How To Care For Hardy Kiwi Properly?
To give your hardy Kiwi proper care, you should consider some crucial factors, such as light, soil, fertilizer, humidity, and temperature.
Regarding light, these plants may tolerate various light conditions, including shade or sun. Yet, plant Kiwis in a location with full sun for them to bloom and bear fruit.
This factor is necessary for all hardy Kiwi varieties, not only the one you selected to grow.
Second, give your hardy Kiwi sufficient water until they take root. You should water them weekly, especially in dry climates.
Besides, choose loamy, fertile, and well-drained soil with a pH between 5 and 6.5 to plant your hardy Kiwi fruit to help them grow best.
In terms of humidity and temperature, hardy Kiwis may thrive in Winter in most places. Yet, you should consider protecting your plants in the early frost period.
Also, give these Kiwis a nitrogen-rich fertilizer to arm them with enough essential nutrients and make the Kiwi vine more vigorous.
How To Propagate Hardy Kiwi?
If you want to propagate Kiwi vine trellis, follow the simple steps below:
- Prepare gloves, pruning shears, four-inch potting soil mixed with vermiculite, and powdered rooting hormone.
- Choose softwood cuttings of 5 to 8 inches in length and ½ inch in diameter in Summer and cut below the node of leaves. Remove these leaves from the cutting bottom, leaving only the top set.
- In the potting medium, make a hole, dip this cutting in the root powder, and insert it 1 inch deep into the hole.
- Water the plant’s pot, drain it thoroughly, and place it in a sunny, warm indoor position. Rooting will often occur within 6-8 weeks. When they are 4 feet tall, let your plants harden before transplanting them outdoors.
When Can You Harvest the Hardy Kiwi’s Fruit?
You may harvest hardy Kiwifruits in early Autumn when they are hard with black seeds inside. Immediately eat these fruits or store them in the fridge for several weeks.
How Fast Can Hardy Kiwi Grow?
They may grow fast in size to reach about 6 – 12 feet per year. The growth of Kiwi vines is rapid, with a size of about 10 to 20 feet each growing season to quickly cover a pergola or arbor.
I’ve provided a complete guide on planting the hardy Kiwi trellis with detailed steps and proper care.
To start growing your Kiwis with the best result, remember to select a suitable site with favorable conditions, such as light, soil, humidity, or weather.
Besides, prepare the healthy Kiwi variety and the sturdy trellis or supports to build a perfect vine when planting Kiwis in your garden.
The right fertilizing, irrigation, and pruning are also necessary to help your Kiwi vine yield flowers and sweet fruits.
