• Fast-growing climbing vine
• Fragrant white flowers
• Edible berries rich in vitamin C
• Ornamental foliage with pink, white, and green variegation (especially on male plants)

How to Grow Kiwi Fruit (Actinidia kolomikta)

Climate and Location

Actinidia kolomikta thrives in cool to cold climates, making it ideal for regions where traditional kiwi vines fail.

Best conditions:

• USDA zones: 3–8
• Full sun to partial shade
• Sheltered from strong winds
• South or east-facing location preferred

Soil Requirements

Healthy soil is essential for strong vines and abundant fruit.

Ideal soil conditions:

• Well-draining loam
• Slightly acidic pH (5.5–6.5)
• Rich in organic matter
• Moist but never waterlogged

Adding compost or aged manure before planting significantly improves results.

Planting Kiwi Vines

• Plant in early spring after frost risk passes
• Space plants 8–12 feet apart
• Install trellises, pergolas, or fences at planting time
• Water deeply after planting

⚠️ Kiwi vines are climbers—strong structural support is non-negotiable.

Male and Female Plants

Actinidia kolomikta is dioecious, meaning male and female flowers grow on separate plants.

• 1 male plant can pollinate up to 6–8 female plants
• Only female plants produce fruit
• Male plants are often more colorful

Propagation Methods for Actinidia kolomikta

Propagation by Cuttings (Most Reliable)

1. Take softwood cuttings in late spring
2. Cut 4–6 inch sections below a leaf node
3. Remove lower leaves
4. Dip in rooting hormone
5. Plant in moist, sterile growing medium
6. Keep warm and humid until roots form

Rooting usually occurs within 4–6 weeks.

Propagation by Seeds

• Clean seeds from ripe fruit
• Cold stratify for 6–8 weeks
• Sow in early spring
• Germination can take several weeks

⚠️ Seed-grown plants may not match the parent plant and take longer to fruit.

Layering

Low-growing vines can be bent to the ground, buried partially, and rooted while still attached to the parent plant.
