How to grow kiwi berry
Overview
Kiwi berry is a vigorous, deciduous climbing vine grown for its smooth-skinned, sweet, bite-sized fruit. It requires both male and female plants for pollination and needs a strong support structure like a trellis or pergola to thrive.
Varieties
- Issai — A self-fertile variety, but still benefits from a pollinator for heavier crops.
- Ken's Red — Red-skinned fruit with excellent flavour, popular in home gardens.
- Meader — A productive female variety, good for cooler climates.
Soil Preparation
Kiwi berry prefers deep, well-drained loam with a pH of 5.5-6.5. Enrich with compost and aged manure before planting. Ensure excellent drainage to prevent root rot; raised beds are ideal in heavy clay.
Growing Guide
Plant in full sun in well-drained, fertile soil with a pH of 5.5-6.5. Space vines 2-3m apart on a sturdy trellis or wire support. Set one male for every 6-8 female plants. Water deeply during dry spells, especially in the first two years. Mulch heavily to keep roots cool and moist.
Care
Feed with a balanced organic fertiliser in early spring and again after fruit set. Prune in winter to remove old or tangled wood, training new growth to supports. Thin fruit clusters to improve size and quality.
Companion Planting
Grow kiwi berry alongside other climbing plants like passionfruit or grapes on the same trellis. Avoid planting near shallow-rooted vegetables that compete for water. Good companions include strawberries, blueberries, and rhubarb under the vine.
Common Pests & Risks
Scale mites and thrips can cause leaf damage; control with horticultural oil in winter. Root rot (Phytophthora) occurs in poorly drained soil; avoid by planting in raised beds. Leafrollers may attack young shoots; use netting or organic sprays.
Harvesting
Harvest kiwi berries when they are fully coloured and slightly soft to the touch, usually from late summer to autumn. They ripen over several weeks; pick individually as they soften. Fruit stores for 2-3 weeks in the fridge.
In the Kitchen
Eat fresh, skin and all, or use in salads, smoothies, and desserts. Kiwi berries are sweeter than kiwifruit and need no peeling. Store in a cool place for up to 3 weeks.
Troubleshooting
Yellow leaves: often due to iron deficiency in alkaline soil; apply chelated iron. Brown leaf edges: caused by wind or salt burn; shelter vines and avoid salty water. Poor fruit set: lack of a male pollinator nearby; plant a male vine within 10m. Fruit drop: inconsistent watering during dry spells; maintain even moisture. Leaf curl: thrips or aphids; spray with neem oil in spring.
