What Kind of Trellis Should Be Used for Kiwi?

Pergolas

• Pergolas consist of an overhead framework supported by a post on each corner. The framework supports the kiwi vines above, allowing the fruit to dangle below for easy harvesting. Pergolas are as decorative as they are utilitarian. Erect a pergola trellis above an existing or new outdoor seating area. The pergola frame and kiwi vines above provide shade to the area above. Pergolas work best for kiwis planted as decorative, edible landscaping. It's also a suitable support in small gardens where locations must provide for two purposes, such as growing kiwis over a walkway.

Wire Trellis

• A wire trellis requires minimal labor and cost to erect. These trellises consists of two posts placed 3 to 6 feet apart. Wires stretch between the two posts, typically with one wore placed near the top of the posts and a second placed near the center. The top wire sets 6 feet from the ground. As the kiwi vine grows, it's lateral shoots are draped and tied to the wire closes to the the shoots origination point. Wire trellises support the vines spread out, making it simple to inspect the entire vine for harvesting, pruning and general maintenance.

T-bar Support

• A T-bar trellis has two posts set 6 feet or more apart. These end posts have a cross beam on top, giving the posts their T-shape. Four wires stretch between the two posts, evenly spaced along the crossbars. To train kiwis to this system, individual stakes are installed for each plant between the two T-bars. Once the vines reach the top of the stakes, the kiwi vines are stretches along the wires and tied in place. You harvest the kiwis from overhead. A T-bar trellis provides a permanent, sturdy framework for your kiwi planting.

Trellising Tips

• Kiwis climb on their own, but the heavy vines require some additional support to prevent them from pulling away from the trellis. Tie the vines loosely to stakes, posts and wires using cloth plant ties or strips cut from old pantyhose. Avoid tying too tightly, as tight ties can damage the vines as they grow. Prune each vine so it only has two leaders, or main stems. Too many leaders results in an overgrown, poorly producing kiwi plant. Cut out the excess leaders when the vine is dormant in winter. Keep the leaders straight up the poles or up to the wire. Stretch out lateral vines so they are at a right angle to the leader vines, pruning away any that aren't positioned right for training the wires or trellis support.
