Araucaria scopulorum Plant Care

Araucaria scopulorum (Araucaria scopulorum) belongs to the Araucariaceae family within the Araucaria genus. Araucaria scopulorum is native to New Caledonia.

Araucaria scopulorum displays a tall, conical tree growth habit, reaching up to 100 ft tall with a spread of approximately 30 ft. Araucaria scopulorum produces rarely flowers, small cones.

Leaf size: approximately 6 inches.

Water a young or newly planted Araucaria scopulorum every 7–14 days, soaking the whole root zone, until it is established — usually one to two growing seasons. Established trees mainly need water during long dry spells. In a container, water whenever the top few centimetres of soil are dry.

Araucaria scopulorum thrives in full sun to partial shade.

Araucaria scopulorum tolerates temperatures of 50–80°F. Araucaria scopulorum prefers humidity levels of 50–70%. A pebble tray or humidifier helps maintain adequate moisture around the plant.

Well-draining, acidic soil with high organic matter content. Good drainage is essential for Araucaria scopulorum to prevent waterlogging, which leads to root rot and fungal issues.

Feed Araucaria scopulorum every 8 months during the growing season with a balanced, slow-release fertilizer at the rate on the label. Established trees in good soil often need little extra feeding, so let weak growth or pale foliage guide you.

Stop feeding by late summer so new growth can harden before winter.

The PlantoScan app can remind you when to water and when to fertilize each plant.

Choose a spot with full sun to partial shade and well-draining, acidic soil with high organic matter content. Avoid low spots where water collects after rain.

Araucaria scopulorum is suited to USDA Zone 10b – 11b.

Plant container-grown or balled-and-burlapped trees in spring or early autumn, setting the root flare at soil level, and water well after planting.

Araucaria scopulorum can spread to about 30 ft (9.1 m) and reach about 100 ft (30 m) tall. Space plants about 30 ft (9.1 m) apart so mature crowns don't crowd each other, and plant at least half that distance from buildings, fences and paths.

Prune Araucaria scopulorum while it is dormant in late winter: first remove dead, damaged and crossing branches, then thin lightly for shape.

If it flowers in spring, prune right after flowering instead so you don't remove next year's buds. Never take off more than about a quarter of the tree in one year.

Araucaria scopulorum is frost-tender (hardy to USDA zone 10). In colder areas grow it in a container and move it to a bright, frost-free place before the first frost.

Araucaria scopulorum can be propagated through seeds, cuttings. Similar propagation techniques also apply to norfolk island pine plant care, which shares the same genus.

Araucaria scopulorum is susceptible to aphids, scale insects. Inspect the foliage regularly, especially along leaf undersides and stems. Treat infestations promptly with insecticidal soap or neem oil to prevent spread.

Araucaria scopulorum grows outdoors in USDA Zone 10b – 11b. It survives winters down to planting zone 10b. Araucaria scopulorum is native to New Caledonia. In cooler regions, grow Araucaria scopulorum as a houseplant or bring it indoors before the first frost.
