    About Araucaria columnaris

    Araucaria columnaris, the Cook Pine, is a narrow evergreen conifer from New Caledonia. Short needle-like foliage is held in dense horizontal tiers around a slender, almost telegraph-pole trunk, giving a strict columnar outline. Mature trees lean consistently toward the equator, an odd habit that makes an established row instantly recognisable.

    It reaches 20 to 25 metres tall and only 4 to 6 metres wide, growing 40 to 70 centimetres a year. Full sun, free draining sandy soil and open exposure suit it, and it shrugs off salt spray and strong coastal wind. It is frost sensitive, so it belongs in frost-free coastal, subtropical and tropical districts.

    The vertical form makes it a natural choice for avenue planting, civic and resort landscapes, and feature positions where a strong upright line is wanted. It casts a narrow shadow, so it can be used close to paths and buildings. Allow 3 metres for an avenue and 3 to 4 metres for freestanding specimens.

    Frequently Asked Questions

    About Cook Pine

    What is Araucaria columnaris?

    Araucaria columnaris, the Cook Pine, is an evergreen conifer from New Caledonia in the family Araucariaceae. It has a strongly columnar habit, with short needle-like foliage arranged in dense tiers along horizontal branches. Being a conifer it produces cones rather than flowers, and it holds its foliage all year.

    How big does Cook Pine grow?

    It reaches 20 to 25 metres tall with a spread of only 4 to 6 metres, so it takes up very little ground area for its height. That narrow footprint is the reason it is used in tight avenues and courtyards. Give it room above rather than beside, and keep it clear of overhead services.

    How fast does Cook Pine grow?

    It grows around 40 to 70 centimetres a year in warm coastal conditions, which is fast for a conifer. Growth slows in cold or dry inland positions. Advanced stock in larger containers already carries the tiered branching that gives the tree its character, so the effect is immediate rather than something to wait for.

    Is Cook Pine suitable for coastal positions?

    It is one of the better conifers for exposed coastal sites. It tolerates salt spray, sandy soil and constant onshore wind, and holds its symmetrical form where broadleaf trees become wind-shorn. It is widely planted along foreshores and around resorts in northern Australia for exactly that reason.

    Is Cook Pine frost tolerant?

    No. It is frost sensitive and best kept to frost-free positions. Young trees can be killed outright by a hard frost, and even established trees show foliage burn after cold nights. In marginal districts, plant it in a sheltered courtyard with warmth radiating from nearby walls, or choose a hardier conifer instead.

    Does Cook Pine have invasive roots?

    Its roots are not aggressive in the way that figs or willows are, but a tree of this height develops a substantial anchoring system. Allow at least 3 to 4 metres between the trunk and any slab, wall or pipe run. On sandy coastal soils the surface roots spread wider in search of moisture.

    How do I care for Cook Pine?

    Water regularly for the first two years while the root system establishes, then it needs very little. Do not prune the leader, since the tree will not replace it and the shape is lost permanently. Remove only dead lower branches. A light application of complete fertiliser in spring is enough on poor sandy soils.

    Planting Information

    How To Plant Your Araucaria columnaris

    Site: Choose a well-drained position in full sun to part shade with room for the canopy to develop.

    Soil preparation: Enrich the planting area with quality compost and aged manure for a strong establishment phase.

    Hole: Dig twice as wide as the root ball and the same depth.

    Planting: Position level with the surrounding soil, backfill gently, firm in, then water deeply to settle the roots.

    Recommended Planting Spacing For Your Araucaria columnaris

    Hedging and screening: 1 to 1.5 metres apart for a dense informal screen, or 80 centimetres apart for a tighter formal hedge.

    Feature tree: 3 to 4 metres apart to allow the full canopy and form to develop.

    Avenue planting: 3 metres apart for a uniform soft-textured avenue.

    Araucaria columnaris is expected to grow 40cm to 70cm per year.

    • Medium Growth Rate

    Long Term Care For Your Araucaria columnaris

    Watering: Water deeply twice weekly through the first 12 months. Once established, this is drought tolerant and only needs a deep soak during extended dry periods.

    Mulching: Apply a 5 to 7 centimetre layer of organic mulch over the root zone, keeping it 5 centimetres clear of the trunk.

    Pruning: Tip prune in late winter and again in summer to build dense growth. For a formal hedge, light shaping two to three times a year keeps lines crisp.

    Fertilising: Apply a slow-release general-purpose fertiliser in early spring and again in autumn for steady growth and consistent foliage colour.

    Pest and disease: Hardy against most pests and diseases. Occasional inspection in warm humid conditions is all that's needed.

    Planting Your Araucaria columnaris in Different Soil

    Araucaria columnaris performs best in free-draining loam or sandy loam with a neutral to slightly alkaline pH. Adaptable to a wide range of soils when drainage is sharp.

    Sandy soil: Free-draining and ideal. Mulch lightly to moderate surface temperature.

    Clay soil: Improve drainage with gypsum and coarse organic compost before planting.

    Loam: The preferred soil for steady root development and consistent growth.

    pH: Neutral to slightly alkaline preferred. Avoid waterlogging at all times.

    Plant Your Araucaria columnaris With:

    Enriched Planting Mix (AO Certified)

    Enriched Planting Mix is a certified organic blend of Pure Magic Compost, composted animal manure, gypsum, composted coarse bark and a wetting agent, bagged in 30L. It is built to be dug through existing garden soil at planting time rather than used on its own, and the gypsum is what sets it apart from a plain compost.

    Gypsum helps break up heavy clay so water and roots can move through it, while the compost and manure return organic matter and nutrient to tired ground. The coarse bark holds structure and keeps air around the root zone, and the wetting agent keeps moisture in the soil longer after rain or watering.

    Use it when planting trees, shrubs, roses, fruit trees and exotic garden plants, particularly into clay. Dig a hole twice the width of the pot and 7 centimetres deeper, then mix roughly one third planting mix through the excavated soil. Spread 7 centimetres of that improved soil in the base before setting the plant in.

    Frequently Asked Questions

    About Enriched Planting Mix

    What is Enriched Planting Mix made from?

    It is a blend of Pure Magic Compost, composted animal manure, gypsum, composted coarse bark and a wetting agent. Each part has a job. The compost and manure supply organic matter and nutrient, the gypsum works on clay structure, the bark keeps air around the roots and the wetting agent holds moisture in the soil.

    What plants is it suitable for?

    It suits exotic garden plants, including roses, ornamental and deciduous trees, fruit trees, shrubs and perennials, and it earns its keep most on heavy clay sites. It is a planting mix rather than a potting mix, so its job is improving soil at planting time. Phosphorus sensitive natives are the one clear exception.

    Is it safe for natives?

    No, not for the phosphorus sensitive ones. The composted animal manure in this blend lifts phosphorus well above what Proteaceae such as Banksia, Grevillea, Hakea and Protea will tolerate, and the result can be leaf burn, dieback and plant death. Use the Native Potting Mix for those species, or plant them into unimproved local soil.

    Is it certified organic?

    Yes. It is a certified organic product with no chemical additives, which is why the manure and compost in it are fully composted rather than raw. That makes it sound around fruit trees and vegetable beds, and it means you are adding genuine organic matter to your soil rather than a synthetic conditioner.

    How much do I need?

    Work on roughly one third planting mix to two thirds of the soil you dug out of the hole. For a shrub out of a 200 millimetre pot that is only a few litres. An advanced tree going into a large hole will take considerably more. Judge the quantity by the volume of the hole rather than the size of the plant.

    Can I use it in pots?

    It is not a potting mix and should not be used on its own in a container. The blend is designed to be diluted through garden soil, and used straight in a pot it holds too much water and settles badly. For containers, reach for a premium potting mix, or the native mix if you are potting natives.

    Does it need to be watered in?

    Yes. Water the plant well several hours before you plant it, then water thoroughly again once the hole is backfilled and the soil firmed down. That first deep watering settles the improved soil around the root ball and drives out air pockets. Keep the water up over the first few months while the roots establish.
