Araucaria Other Varieties
Araucaria are mainly large trees with a massive erect stem, reaching a height of 30–80 metres (98–260 ft). The horizontal, spreading branches grow in whorls and are covered with leathery or needle-like leaves. In some species, the leaves are narrow awl-shaped and lanceolate, barely overlapping each other, in others they are broad and flat, and overlap broadly.
They are found in forest and maquis shrubland, with an affinity for exposed sites. These columnar trees are living fossils, dating back to early in the Mesozoic age. Fossil records show that the genus also formerly occurred in the northern hemisphere until the end of the Cretaceous period. By far the greatest diversity exists in New Caledonia, due to the island's long isolation and stability.
Origin: Norfolk Island
Height: Up to 6 ft (1.8 m), grown in a pot indoors
Light: Bright light with some full sun. Rotate the pot occasionally in front of the window to give all sides light for even growth.
Water: Keep the soil evenly moist in the spring and summer, lightly moist in winter. Always use tepid water for watering your houseplants.
Humidity: Moderate room (50% relative humidity) or higher. The most efficient way to boost humidity for your tropical plants is to use a small cool-mist humidifier. Dry, yellowing needles are a sign the air is too dry.
Temperature: Average room temperatures 65-75°F/18-24°C. Norfolk Island pine doesn't like the cold, so don't expose it to temps below 50°F/10°C.
Soil: Soil-based potting mix.
Fertilizer: Feed every 2 weeks spring through fall with a balanced water-soluble fertilizer diluted by half.
Propagation: Can be grown from seed, although it will take several years to reach the size of a purchased plant.
