Araucaria columnaris, as described in 1786 by Johann Reinhold Forster, in Florulae Insularum Australium Prodromus, 67 edition, is commonly known as the coral reef araucaria, Cook pine, New Caledonia pine, Cook araucaria, or columnar araucaria. It was first classified by botanists working on Captain James Cook's second voyage of exploration. The Coral reef araucaria is often confused with the Norfolk Island pine (A. heterophylla) because of their similar appearance.

How to Care for the Plant

Water

During the active growth period water plentifully, as often as necessary to keep the potting moisture thoroughly moist, but never allow the pot to stand in water. During the rest period water moderately, enough to make the potting mixture thoroughly moist, but allow the top 2-3cm (0.8-1 inch) to dry out between waterings.

Pruning

Do not trim or prune the Araucaria heterophylla. Never cut off the top or trim the sides of this plant. It does not need to be shaped at all. Remove any lower branches that die, using sharp pruners to prevent tearing the stems.

Fertilizer

Apply liquid fertiliser to the potting mixture every two weeks in the active growth period.

Sunlight

Araucaria heterophylla do best in medium light. They should not be placed too far from the window, however, or their needles will fall. Turn the plant regularly to encourage symmetrical growth.

Soil

Soil type Clay, Loamy, Sandy

Temperature

A wide range of temperatures (ideally 7-24oC (45-75oF)) can be tolerated. Above 27oC these conifers must have high humidity; mist-spray the foliage occasionally. Provide some ventilation or stand outside during the summer months.

Additional

Some people may experience a strong allergic reaction if they touch the leaves.
