Expert tips
The key tip
Actinidia arguta needs a very sturdy framework (steel or solid wood): its vigor is formidable. Pinch at 50-60 cm height for rapid branching.
The common mistake
Letting it grow without targeted pruning creates a tangle that can weaken the small fruits before ripeness.
The pro's trick
Harvest the fruits while still firm in September-October and let them ripen in a crate.
Care
Exposure
Plant your hardy kiwi in partial shade or full sun, with at least a few hours of direct sunlight daily to encourage fruiting. Avoid exposure to strong winds that can damage the stems. A protected location, even if partially shaded, works well.
Watering
Keep the soil moist during growth and fruiting, from May to September. Water regularly during dry periods, without creating waterlogging. Reduce watering in winter. Hardy kiwi appreciates moderate and consistent moisture.
Soil and planting
Prepare rich, well-draining soil that is slightly acidic to neutral. Enrich with compost or potting soil at planting time. Install a sturdy support (trellis, pergola) as the plant becomes very large and heavy when mature.
Pruning and training
Train the main stems along your support as they grow. In winter or late autumn, prune to shape the structure, aerate it, and remove dead wood. Also cut back overly long shoots after harvest to maintain balance.
Fertilizing
Apply compost or balanced fertilizer in spring at the start of growth. A second application can be made in early summer. Avoid excess nitrogen, which would encourage foliage at the expense of fruit.
Pests and diseases
Hardy kiwi is generally robust. Watch for powdery mildew in humid conditions: ensure good air circulation around the plant. Slugs and snails may damage young leaves. Good drainage prevents root rot in winter.
Did you know?
Hardy kiwi is the wild ancestor of cultivated kiwi (Actinidia deliciosa) and produces much smaller, smooth fruits without fuzz. Known in Northeast Asia for centuries, it was long overlooked in the West, yet it rivals its larger cousins in flavor, with the added advantage of being eaten whole, skin included.
Where to buy it
Best planted in autumn so the roots settle in before summer, or in early spring once the frost has passed. Pick a plant with healthy foliage and roots that are not exposed. Best time: March, October, November.
