What makes Weiki (mannelijk) special?

Flavour and kitchen

This male selection does not bear fruit itself.

Choose this plant to pollinate a suitable female selection.

Growing and harvesting this variety

Vigorous climber on sturdy support; sunny, sheltered and well drained.

No harvest of its own; check flowering overlap with the female cultivar.

  1. Choose a suitable fruiting/pollinator pair.
  2. Install sturdy support.
  3. Train young branches outwards.
  4. Prune to keep the plant accessible.

  1. Check the partition's stability.
  2. Plant somewhere warm and sheltered.
  3. Train trunk and side branches along wires.
  4. Follow flowering and eating ripeness.

What do you want from your garden?

Small, smooth kiwis can be eaten straight away like grapes. Red Ken's Red adds extra colour.

Flavour and use

Kiwi-like sweetness and acidity; eat the smooth skin too.

Choose a suitable spot

Vigorous climber on sturdy support; sunny, sheltered and well drained.

From flower to fruit

Issai is self-fertile. Ken's Red is female; use a suitable male Weiki. Weiki is also sold as a female plant: check the sex.

How to give the plant a place

Hardy kiwi on a pergola: Choose a compatible fruiting plant/pollinator pair. Install sturdy support. Train young branches outwards. Prune to keep the plant accessible.

Issai along a garden boundary: Check the boundary’s strength. Plant somewhere warm and sheltered. Train trunk and side branches along wires. Follow flowering and eating ripeness.

Care throughout the season

Train and prune; young growth remains vulnerable to late frost.

Recognise the right time to pick

Pick when truly ready to eat; do not adopt a colour rule from fuzzy kiwi.

Follow your own harvest

Record the pollinating male Weiki separately without claiming a fruit harvest.

Turn your space into a garden for experimenting

Design a sturdy climbing structure first. Kiwi and hardy kiwi produce vigorous growth; a thin cane is not a permanent framework. Train a trunk upwards and spread the selected framework branches along the support. Tie with loose, soft loops and check for constriction. Also leave a route clear for picking fruit and pruning the plant.

Pollination starts with the label. Record whether your plant is male, female or self-fertile and check that flowering periods match. A male plant is a useful pollinator but does not produce fruit itself. Where a name is used for both male and female selections, the sex must remain explicit. The same name on two pots alone does not prove the combination is suitable.

Distinguish kiwi from kiwi berry when tasting. Kiwi berries have small fruits with smooth, edible skin; an ordinary kiwi is picked and eaten differently. Give the plant time to build a framework and record actual flowering and ripening. The app can link the species to your garden, but a fixed number of days from planting does not reliably predict the first harvest from these perennial climbers.

Which flavour would you like to discover?

Issai: Self-fertile; small smooth fruit.

Ken's Red: Female; reddish fruit.

Weiki (mannelijk): Pollinator; no fruit of its own.

When and how should you prune?

Period for assessing pruning: Jan · Jul · Aug. This is a seasonal window for a temperate garden in the northern hemisphere; check actual dormancy, growth and weather conditions.

During winter dormancy, assess the framework and productive replacement wood. Train and restrict vigorous new growth in summer; retain enough wood for future flowers and fruit. Do not blindly prune away all young vines.

A young plant needs shaping; an established one needs maintenance and gradual renewal. First consider which branches you want to keep. Use clean, sharp tools and avoid unnecessary large wounds. A pruning check does not mean cutting every time.

My vegetable garden shows a suitable check for confirmed pruning periods. A variety-specific period takes precedence over the general species period. Planned and finished crops receive no pruning task; no European calendar is applied without a confirmed location.
