Mini Kiwi Varieties

Popular Female Varieties

Issai - A self-fertile variety that doesn't require a pollinator. Produces medium-sized fruits with excellent sweet flavor. Ideal for smaller gardens.

Ken's Red - A unique variety with red flesh and skin. Very sweet flavor with higher sugar content. Requires a male pollinator.

Geneva - One of the most productive varieties with large fruits. Excellent flavor and good storage qualities.

Weiki - A German variety with very large fruits (up to 15g). Excellent taste and high yields. Ripens in September.

Male Pollinators

For pollination of female varieties, you need a male plant. One male can pollinate up to 8 female plants. The most commonly used pollinator is the variety Male or Adam.

Growing Mini Kiwi

Location and Soil

Mini kiwi prefers:

Sunny to partially shaded location - at least 6 hours of sunlight daily
Protection from strong winds - especially during flowering
Fertile, well-drained soil - pH 5.5-7.0
Sufficient moisture - but not waterlogged
Humus-rich soil - add compost or well-rotted manure

Planting

Best planting time is spring (March-April) or autumn (September-October). Space plants 2-3 meters apart. Dig a planting hole twice the size of the root ball and enrich the soil with compost.

Important: Plant at least one male plant for every 3-8 female plants for successful pollination.

Support System

Mini kiwi is a vigorous climber that needs strong support:

Pergola or arbor - ideal for creating shaded seating areas
Wire trellis - tension wires stretched between posts
Wall with supports - for vertical growing on buildings
Fence - can be used as a living screen

The support must be sturdy as mature plants can be very heavy.

Mini Kiwi Care

Watering

Mini kiwi has high water requirements, especially during fruit development. Water regularly, particularly during dry periods. The soil should be consistently moist but not waterlogged. Mulching around plants helps retain moisture.

Fertilizing

In spring (March-April), apply compost or well-rotted manure. During the growing season, you can supplement with organic fertilizers:

Compost - 2-3 cm layer around plants
Organic fertilizer - according to package instructions
Wood ash - source of potassium for better fruiting

Avoid excessive nitrogen fertilization, which promotes vegetative growth at the expense of fruiting.

Pruning

Pruning is essential for abundant harvests and plant health:

Winter pruning (January-February):

Remove old, damaged, and crossing branches
Shorten lateral shoots to 3-4 buds
Maintain the main framework branches

Summer pruning (July-August):

Shorten green shoots beyond fruits to 5-6 leaves
Remove excessive vegetative growth
Improve light and air circulation in the canopy

Harvesting and Storage

When to Harvest

Mini kiwi fruits ripen from late August to October, depending on the variety. Fruits are ready to harvest when they:

Are slightly soft to touch
Have full color (green, red, or purple depending on variety)
Have sweet flavor - taste one fruit for ripeness
Detach easily from the stem with gentle pulling

Tip: Fruits don't all ripen at once - harvest gradually over several weeks.

Storage

Fresh mini kiwi fruits can be stored:

At room temperature - 3-5 days
In the refrigerator - 2-3 weeks
Frozen - up to 12 months (whole or sliced)

Kiwi That Can Be Grown in Our Climate

Kiwi, also known as hardy kiwi (actinidia arguta), has its roots in China. Although this climbing fruit vine commonly grows in southern regions, there is one type of kiwi that we can grow even in our conditions. This is a special variety of mini kiwi. This variety easily survives our frosts and what's more, it produces a large quantity of small kiwi fruits every year. Kiwi is typically a dioecious plant. However, this mini kiwi variety is available as self-pollinating. Therefore, no male plant is needed alongside the female plant.

Fruit Full of Vitamins

Kiwi is very rich in Vitamin C. With just one fruit, you'll ensure your daily intake of this important vitamin, which is especially needed during flu and cold season. The potassium content also positively affects blood pressure. In addition, kiwi is rich in fiber and other beneficial substances.

About Growing

Growing mini kiwi in our climate is surprisingly simple. Mini kiwi is hardy up to an altitude of around 650 m above sea level and tolerates temperature drops down to -27°C! An important characteristic of mini kiwi is that it's very resistant to pests. Mini kiwi essentially has no natural enemies here. Mini kiwi is not affected by pests, mildew, or fungi in our conditions.

Mini kiwi is not suitable for growing as a houseplant. As already mentioned, mini kiwi is a climbing vine. Given the plant's frost resistance, it would be a shame not to plant the kiwi outdoors. The plant thrives on walls, balconies, or pergolas.

Pre-growing Kiwi Seedlings

Seeds cannot be sown directly in the bed or location where you'll want the mini kiwi in the future. Pre-growing young seedlings is an important phase. You can read more about growing mini kiwi from seeds in the Growing Guides section.

Young seedlings can be transplanted outdoors into open soil practically year-round. The most important prerequisite for this step is the largest possible root system. If you pre-grow two-year-old seedlings, that's certainly ideal.

What to Follow When Planting Kiwi?

Mini kiwi loves sun and shows it very clearly. To ensure a good fruit harvest, it's necessary to plant the plant in the most illuminated location possible. If the plant is planted on the leeward side, it's good to preventively protect the plant in winter with conifer branches, leaves, or non-woven fabric.

Young mini kiwi plants can be planted practically anytime. It depends primarily on the quality of the plant's root system. It's good to dig fertilizer under the young seedling for better growth. Mini kiwi grows very quickly and at its pace needs sufficient nutrients. Mini kiwi can be grown in regular garden substrate.

Good Mini Kiwi Harvest

Mini kiwi is a climbing plant that doesn't like to branch naturally. It creates long branches up to 5 m in length. Therefore, it's advisable to pinch the plant to achieve the highest possible yield. It's best to shorten branches from a length of 15 cm onwards. When branching, you should avoid creating a tangle of branches. Keep in mind the simple rule that each branch should have space around it for future flowers and fruits. The entire plant should be evenly distributed on the support structure to catch as much light as possible and not shade itself.

Harvesting Sweet Fruits

Mini kiwi harvest comes in autumn. Similar to grapevines, mini kiwi isn't bothered by light frosts before harvest. On the contrary, short frosts can even improve the flavour of the fruits. Therefore, it's recommended to wait until the plant experiences a few frosts. And this is precisely the best time to harvest these small fruits, which are approximately 2.5 cm in size.

Besides size, mini kiwi also differs from regular varieties in taste. These small fruits are sweeter and even contain more Vitamin C. And it's in autumn that you can ensure your own supply of this and many other vitamins. In addition to these advantages, the mini kiwi variety has another great benefit. The fruits don't form a tough skin, so mini kiwi doesn't need to be peeled.
