Grow Actinidia kolomikta 'September Sun' when you want a tough, cold-hardy vine that looks ornamental even before it fruits. This variegated kiwi vine develops eye-catching green leaves splashed with white and pink, then produces small, smooth-skinned edible kiwi berries on female plants when a compatible male plant is nearby. Give it sturdy support from the start (arbor, trellis, fence, or wires), because mature vines can become heavy as they age.
Place your Variegated Kiwi Vine 'September Sun' in full sun to part shade; more sun generally means stronger growth and better fruiting, while a little afternoon shade can help in hot summer areas. Plant in fertile, evenly moist, well-drained soil and water consistently through establishment. A mulch ring helps moderate soil moisture, but keep mulch off the stem to prevent rot.
Plan on regular pruning to keep the vine manageable and productive. Prune during dormancy in winter to early spring, and train new growth along your support so it fills the space evenly. Because this species is dioecious, you will get fruit only when a male pollinator is present; if you are growing it mainly for foliage, you can still enjoy its variegation without fruit.
One practical note: kiwi vines can attract cats, which may chew or damage young plants. Protect new growth until it is established, and check ties and supports each season so the vine stays secure.
