How to Grow Actinidia Arguta from seed

Hardy kiwi seeds need a period of cold to break dormancy.

1. Mix the dried seeds with a small amount of moist vermiculite, sphagnum moss, or a damp paper towel.

2. Place the mixture into a sealed plastic bag.

3. Store in the fridge (not freezer) for 8–12 weeks at around 4 °C.

4. Check periodically to ensure the medium stays slightly moist and not mouldy.

Sowing the Seeds

After cold stratification:

1. Prepare seed trays or small containers with a fine seed-raising mix.

2. Sprinkle seeds on the surface and lightly press them in; do not cover deeply (they need light to germinate).

3. Mist gently with water.

4. Cover with a clear plastic lid or cling film to retain humidity.

5. Place in a warm, bright location (around 20–25 °C) but out of direct sun.

Germination and Care

• Germination usually occurs within 2–6 weeks, but it can take longer.

• Once seedlings appear, remove the cover to prevent damping off.

• Keep soil moist but not soggy.

• Thin out weaker seedlings once they’re big enough to handle.

---

Transplanting

When seedlings develop a few sets of true leaves:

1. Transplant them into small individual pots.

2. Keep them in a sheltered spot (like a greenhouse or indoors) until they’re strong enough to go outside.

Planting Outdoors

After a year or so of growth:

• Choose a sunny site with well-drained soil.

• Provide a sturdy trellis or structure—they're vigorous climbers.

• Ensure plants have space to grow and are protected from strong wind.

---

Notes

• Seed-grown plants take 4–7 years to fruit.

• Actinidia arguta is dioecious—you’ll need at least one male plant for pollination.

• Only female plants produce fruit, so you might need to grow several to ensure good results.

Hardy kiwi

Botanical name   Actinidia arguta

Details   A vigorous, deciduous vine native to East Asia, particularly in regions of Japan, Korea, and China.

Unlike the more common kiwi fruit (Actinidia deliciosa), the hardy kiwi produces smaller, smooth-skinned berries that are green to reddish-brown and can be eaten whole without peeling.

The fruit is sweet and rich in vitamin C, making it a nutritious snack.

The plant is cold-hardy and can tolerate temperatures as low as -25°C, making it suitable for cultivation in temperate climates.
