Overview
Pollination is primarily carried out by insects, especially bees.
Notes
Most hardy kiwi varieties are dioecious, meaning there are separate male and female plants. For fruit production, at least one male plant is required for every 5-8 female plants. There are also some self-fertile varieties (e.g., 'Issai'), but they often benefit from an additional male plant.
Pruning & care

Pruning type

Pruning timing
Structure building, fruiting wood renewal, thinning The main pruning is done in late winter when the plant is dormant and before sap rise begins. This minimizes 'bleeding' from cuts.
Growth regulation, fruit exposure to light, promotion of fruit quality In early summer, long, vegetative shoots are shortened to direct energy into the fruits and improve ventilation. Shoots that are not bearing fruit can be cut back more severely.

Preserve

Tools and hygiene
Always use sharp and clean pruning tools to ensure smooth cuts and minimize disease transmission. Disinfect tools regularly, especially after cutting diseased plant parts.

Use & storage
hardy kiwi Use & storage
Fruits ripen from September to October, depending on variety and location.
Storage
Cool and humid
Storage life
Ripe: short (days to 1-2 weeks); Unripe: medium (weeks)
Flavor
Sweet-tart, aromatic, reminiscent of a mix of kiwi, gooseberry, and fig.
Harvest
Fruits ripen from September to October, depending on variety and location.
Culinary uses
Processing
After harvest
Hardy kiwis can either be harvested ripe from the vine or picked unripe and ripened at room temperature. Unripe fruits ripen faster when stored with apples or bananas (ethylene production).

FAQ
Do I need to plant male and female hardy kiwis?
Yes, most hardy kiwi varieties are dioecious, meaning there are separate male and female plants. For fruit production, you need at least one male plant for every 5-8 female plants. However, there are also self-fertile varieties like 'Issai', which still benefit from an additional male plant for higher yields.
When is the best time to prune hardy kiwis?
The main pruning (winter pruning) is done in late winter (January/February), before sap rise begins. Summer pruning for shoot regulation and better fruit exposure is recommended in early summer (June/July) after fruit set.
Why isn't my hardy kiwi bearing fruit?
Common reasons include the absence of a male pollinator plant (for dioecious varieties), insufficient insect pollination, late frost damage to flowers, or incorrect pruning that removed fruiting wood. Very young plants often only bear fruit after 2-3 years.
Can hardy kiwis be grown in containers?
Yes, hardy kiwis can be grown in containers, but they require very large pots (at least 50-90 liters volume) and extremely sturdy support. Regular watering, fertilization, and consistent pruning are essential.
