Oyster Bay Pine Plant Care

Oyster Bay Pine (Callitris rhomboidea) belongs to the Cupressaceae family within the Callitris genus. Oyster Bay Pine is native to Australia, occurring in South Australia, Queensland, New South Wales, Victoria and Tasmania. Oyster Bay Pine is also known as Cypress Pine, Pine.

Oyster Bay Pine displays a tall, conical tree growth habit, reaching up to 30 ft tall with a spread of approximately 10 ft. Oyster Bay Pine produces small, inconspicuous flowers.

Leaf size: approximately 1 inches.

Water a young or newly planted Oyster Bay Pine every 14–21 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.

Oyster Bay Pine thrives in full sun.

Callitris rhomboidea tolerates temperatures of 50–85°F. Oyster Bay Pine prefers humidity levels of 30–60%.

Well-draining sandy soil with good aeration. Good drainage is essential for Oyster Bay Pine to prevent waterlogging, which leads to root rot and fungal issues.

Choose a spot with full sun and well-draining sandy soil with good aeration. Avoid low spots where water collects after rain.

Oyster Bay Pine is suited to USDA Zone 12a.

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.

Oyster Bay Pine can spread to about 10 ft (3 m) and reach about 30 ft (9 m) tall. Space plants about 10 ft (3 m) apart so mature crowns don't crowd each other, and plant at least half that distance from buildings, fences and paths.

Prune Oyster Bay Pine 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.

Oyster Bay Pine is frost-tender (hardy to USDA zone 12). In colder areas grow it in a container and move it to a bright, frost-free place before the first frost.

Oyster Bay Pine can be propagated through seeds, cuttings. Similar propagation techniques also apply to pancheri's cypress plant care, which shares the same genus.
