Actinidia chinensis | Golden Kiwi Fruit

For optimal germination rates, initiate seed propagation indoors under controlled conditions—unless the species exhibits a high sensitivity to root disturbance. This approach allows precise regulation of temperature, humidity, and light, improving germination consistency and seedling viability. Do not skip any recommended seed treatments, as they are essential for uniform and successful germination.

Seed Treatment (Stratification)

  1. Cold Stratification Required

    • Soak seeds in lukewarm water for 24 hours to soften the seed coat.

    • Mix seeds with moist sand or a damp paper towel and place them in a sealed plastic bag.

    • Refrigerate at 35–40°F (2–5°C) for 12 weeks to break dormancy.

    • Check weekly: If seedlings sprout in the fridge, remove them gently and plant immediately.

    • Check periodically to ensure seeds do not dry out or mold.

Planting Instructions

  1. Sowing Indoors (Recommended)

    • Use a well-draining seed-starting mix with added perlite or sand.

    • Lightly press seeds into the soil and cover with a very fine layer of soil or vermiculite (seeds need light to germinate).

    • Use grow lights to maintain 12–16 hours of light per day.

    • Mist soil gently to keep it moist but not soggy.

    • Use a heat mat to maintain steady temperatures of 70–75°F (21–24°C).

    • Germination takes 2-3 Months (AFTER stratification), but some seeds may take longer.

      Humidity: Use a humidity dome or clear cover to maintain consistent moisture during germination. Open the dome BRIEFLY once per day to allow fresh air in and reduce mold risk. Remove the dome entirely once seedlings emerge.

  2. Transplanting Seedlings

    • Once seedlings have 2–3 true leaves, transplant them into larger pots.

    • Keep in a warm, bright location with indirect sunlight.

    • Harden off before planting outdoors by gradually exposing them to outdoor conditions.

  3. Outdoor Planting

    • Choose a sunny, well-draining location with slightly acidic soil (pH 5.5–7.0).

    • Space plants 10–15 feet apart, as kiwis are vigorous climbers.

    • Provide a sturdy trellis or support for vines to grow on.

Care After Germination

  • Keep soil moist but not waterlogged.

  • Fertilize seedlings with a balanced fertilizer every 4–6 weeks.

  • Protect young plants from frost, as they are sensitive to cold.
