Kiwi Fruit

Family: Actinidiaceae

Genus: Actinidia

Species: deliciosa

History

Kiwi fruit originated in China as the Chinese gooseberry but was renamed for marketing purposes in New Zealand. It was introduced to Australia in the 20th century and has since become a favourite for its vitamin C-rich flesh and unique flavour. The name 'kiwi' refers to the small, fuzzy native bird of New Zealand.

Where to Plant

In-Ground Garden Beds

In-Ground Garden Beds
• Traditional garden beds dug directly into the soil
• Suitable for deep-rooted crops and long-term plantings
• Offers natural soil ecology and drainage benefits
• Requires proper soil preparation and weed management

Shady Spots & Herb Gardens

Shady Spots & Herb Gardens
• Areas receiving dappled or indirect sunlight, often near trees or buildings
• Best for shade-tolerant herbs like mint, parsley, or greens like spinach
• Helps prevent sun stress and conserves moisture
• Often used in cooler corners of the garden

Containers & Pots

Containers & Pots
• Portable planting vessels suited for patios, balconies, and small areas
• Provide complete control over soil composition and drainage
• Great for herbs, greens, compact vegetables, or ornamental plants
• Allow plants to be moved to follow sun, shade, or seasonal conditions

Pre-treatment

None Identified

There are no pre treatments required for germination.

Sowing Method

Start in Trays

• Fill seed trays or punnets with quality seed-raising mix
• Sow seeds at the correct depth—refer to seed packet for guidance
• Place trays in a warm, sheltered location with good light
• Mist or bottom-water to avoid disturbing small seeds
• Transplant seedlings once they develop 2–4 true leaves

Direct Sow

• Sow seeds directly into prepared garden soil or outdoor containers
• Best for plants that dislike transplanting, such as root vegetables and beans
• Loosen soil and remove weeds before sowing
• Sow at the recommended depth and spacing, then water gently
• Keep the area moist until germination and thin seedlings if needed

Watering

High

• Requires consistently moist soil, particularly during warm or dry periods
• Best suited to shallow-rooted or leafy plants such as lettuces, leafy greens, and tropical herbs
• May need daily watering in hot, exposed locations or sandy soils
• Avoid letting soil dry out—wilting may occur quickly if moisture is lost
• Use mulch and drip irrigation to maintain even moisture levels

Fertilisation

Frost

Frost Tolerant

These plants can tolerate light to moderate frosts and may survive through cooler seasons.

Maintenance and Harvesting

Kiwi Fruit vines are vigorous growers that need structured pruning to manage their size and fruiting. In winter, prune to a strong central leader and maintain a horizontal cordon system to support fruit-bearing laterals. During the growing season, pinch back excessively long shoots and remove tangling growth to increase sunlight penetration. Kiwi vines are dioecious, so ensure proper male-to-female ratios and prune male plants after flowering. Feed with a potassium-rich fertiliser in spring and maintain deep, consistent watering in dry periods.

Pests and Diseases

Aphids

Aphids are tiny, soft-bodied insects that cluster on new growth and the undersides of leaves. They suck sap from plants, causing leaves to curl, yellow or become distorted. As they feed, they excrete sticky honeydew that encourages sooty mould, and colonies can build quickly in warm weather.

Start with organic controls: blast colonies off with a firm jet of water, encourage beneficial insects like ladybirds and lacewings, and spray neem oil or insecticidal soap to disrupt feeding. Keep plants well watered and avoid excess nitrogen that promotes soft growth. If pressure remains high, selective chemical sprays can be used sparingly, taking care to protect pollinators and beneficials.

Leaf spot

Leaf spot describes several fungal or bacterial diseases that create dark, often round lesions on foliage—sometimes with yellow halos. Severe infections cause premature leaf drop and reduced vigour, especially during warm, wet spells or when leaves stay damp.

Reduce spread by removing infected leaves, watering at the base, and spacing plants for airflow. Mulch to limit soil splash and rotate crops. Organic preventatives include copper and sulfur sprays applied early. If disease escalates, registered fungicides offer a chemical backup.

Crown / root rot (Wet)

Crown and root rots are caused by water‑loving fungi that attack stems at the soil line and roots below. Plants yellow, wilt, and eventually collapse because their roots can no longer supply water and nutrients—most common in heavy, waterlogged soils.

Prevention is key: improve drainage, raise beds, and water deeply but less often. Avoid injuring stems at the soil line and rotate away from affected beds. Solarising soil in summer can knock back pathogens. Chemical drenches have limited benefit in home gardens and are best used preventatively rather than curatively.

Powdery mildew

Powdery mildew appears as a white, talc‑like coating on leaves and stems. It thrives in warm days, cool nights, and still air, and can weaken plants by reducing photosynthesis, leading to yellowing and early leaf drop.

Prune for airflow, avoid overhead watering, and remove badly affected foliage. Organic sprays such as milk solution, potassium bicarbonate, sulfur, or neem help suppress outbreaks. Chemical fungicides are effective when started early, but use sparingly to preserve beneficial organisms.

Downy mildew

Downy mildew causes pale yellow blotches on upper leaf surfaces with grey‑purple fuzz beneath, spreading fast in cool, moist weather. Heavily infected leaves collapse, slowing growth and yield.

Choose sunny, well‑ventilated positions, water early so foliage dries quickly, and remove infected leaves promptly. Organic options include copper and bio‑fungicides (phosphorous acid salts). For severe pressure, rotate chemical fungicide modes to prevent resistance.

Two-spotted spider mites

Two‑spotted spider mites are tiny sap‑suckers that stipple leaves, causing a speckled, yellow look and fine webbing—worst in hot, dry conditions. Unchecked, plants can defoliate.

Increase humidity around plants, hose undersides of leaves, and release or encourage predatory mites. Neem and horticultural oils suppress populations organically. Miticides exist for heavy outbreaks; rotate actives to reduce resistance.

Caterpillars & chewing larvae

Caterpillars and chewing larvae are moth and butterfly young that devour leaves or bore into stems and fruit, reducing growth and spoiling harvests.

Hand‑pick where practical and protect young crops with fine netting. Encourage parasitic wasps and birds. Apply Bacillus thuringiensis (Bt) for an organic, caterpillar‑specific control. Broad‑spectrum insecticides can work but may harm beneficials, so reserve for severe cases.

Thrips

Thrips are slender insects that rasp and suck plant tissues, leaving silvery streaks and distorted growth on leaves and flowers. They can also transmit plant viruses.

Use blue or yellow sticky traps to monitor and reduce numbers, weed around beds, and encourage beneficials like minute pirate bugs. Neem oil and insecticidal soap offer organic suppression. If needed, use registered insecticides and rotate modes of action to avoid resistance.

Slugs & snails

Slugs and snails chew irregular holes in foliage and fruit and can wipe out seedlings overnight, especially in damp, sheltered spots.

Remove hiding places, water in the morning, and use beer traps, boards, or shelters to concentrate and hand‑pick. Copper barriers can deter them. For baits, iron‑based pellets are the safest organic option; use metaldehyde baits cautiously due to risks to pets and wildlife.

Growing Tips

• Kiwi Fruit is prone to requires male/female plants for fruit set (most varieties). Good cultural practices such as timely sowing, consistent care, and soil preparation can help manage this.
• Kiwi Fruit is prone to wind damage to vines without sturdy trellis. Good cultural practices such as timely sowing, consistent care, and soil preparation can help manage this.
• Kiwi Fruit is prone to late spring frost damage to young shoots. Good cultural practices such as timely sowing, consistent care, and soil preparation can help manage this.
