Jackwood Plant Care

Jackwood (Cryptocarya obovata) belongs to the Lauraceae family within the Cryptocarya genus. Jackwood is native to eastern Australia. Jackwood is also known as Native Laurel, Brown Bollywood.

Jackwood displays a tall, evergreen tree growth habit, reaching up to 30 ft tall with a spread of approximately 15 ft. Jackwood produces small, inconspicuous flowers.

Leaf size: approximately 6 inches.

Water a young or newly planted Jackwood 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.

Jackwood thrives in partial to full shade. The optimal light range is 100–500 lux. Avoid placing Jackwood in direct, harsh sunlight for extended periods, as this can scorch the foliage.

Cryptocarya obovata tolerates temperatures of 50–80°F. Jackwood prefers humidity levels of 60–80%. A pebble tray or humidifier helps maintain adequate moisture around the plant.

Well-draining, rich loamy soil with added organic matter. Good drainage is essential for Jackwood to prevent waterlogging, which leads to root rot and fungal issues.

Feed Jackwood 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.

Choose a spot with partial to full shade and well-draining, rich loamy soil with added organic matter. Avoid low spots where water collects after rain.

Jackwood 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.

Jackwood can spread to about 15 ft (4.6 m) and reach about 30 ft (9 m) tall. Space plants about 15 ft (4.6 m) apart so mature crowns don't crowd each other, and plant at least half that distance from buildings, fences and paths.

Prune Jackwood 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.

Jackwood 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.

Jackwood can be propagated through seeds, stem cuttings. Similar propagation techniques also apply to peumo plant care, which shares the same genus.

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

Jackwood grows outdoors in USDA Zone 12a. It survives winters down to planting zone 12a. Jackwood is native to eastern Australia. In cooler regions, grow Jackwood as a houseplant or bring it indoors before the first frost.
