How to Grow Hardy Kiwi
The short answer
Hardy kiwi (Actinidia arguta) is a vigorous woody vine bearing smooth, grape-sized, fully edible fruit sweeter than fuzzy kiwi. It grows in USDA zones 4 to 9 (zone 3 in protected sites or with cold-hardy selections) in full sun to partial shade on well-drained, fertile soil.
You generally need both a male and a female vine to set fruit (self-fertile 'Issai' is an exception). The vine is heavy and fast — it can grow 30 feet in a single year and a fruiting mature vine can weigh over 200 pounds — so build a heavy-duty trellis or pergola before planting. Most cultivars bear their first fruit in 3 to 5 years; 'Issai' can fruit in 1 to 2.
Conditions and pollination
- USDA zones 4 to 9 (zone 3 with protection or hardy selections).
- Full sun to partial shade; well-drained, fertile soil.
- Plant both a male and a female vine for fruit; 'Issai' is self-fertile.
Support and pruning
Build a strong trellis or pergola before planting — a mature fruiting vine can weigh over 200 pounds and will pull down a flimsy structure. In winter, prune each stem back to about 8 to 10 buds, and prune again in summer to control over-long branches.
✔ Expect 3 to 5 years to first fruit on most cultivars; the vine's fast growth in year one is normal.
