Japanese Umbrella Pine Plant Care

Japanese Umbrella Pine (Neoshirakia japonica) belongs to the Euphorbiaceae family within the Neoshirakia genus. Japanese Umbrella Pine is native to east Asia.

Japanese Umbrella Pine displays a tall tree, spreading canopy growth habit, reaching up to 30 ft tall with a spread of approximately 20 ft. Japanese Umbrella Pine produces small greenish-yellow clusters.

Leaf size: approximately 6 inches.

Water a young or newly planted Japanese Umbrella Pine 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.

Japanese Umbrella Pine thrives in full sun to partial shade.

Neoshirakia japonica tolerates temperatures of 65–85°F. Japanese Umbrella Pine prefers humidity levels of 40–70%.

Well-draining sandy loam with added organic matter. Good drainage is essential for Japanese Umbrella Pine to prevent waterlogging, which leads to root rot and fungal issues.

Feed Japanese Umbrella Pine every 6 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 full sun to partial shade and well-draining sandy loam with added organic matter. Avoid low spots where water collects after rain.

Japanese Umbrella Pine is suited to USDA Zone 13b.

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.

Japanese Umbrella Pine can spread to about 20 ft (6.1 m) and reach about 30 ft (9 m) tall. Space plants about 20 ft (6.1 m) apart so mature crowns don't crowd each other, and plant at least half that distance from buildings, fences and paths.

Prune Japanese Umbrella 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.

Japanese Umbrella Pine is frost-tender (hardy to USDA zone 13). In colder areas grow it in a container and move it to a bright, frost-free place before the first frost.

Japanese Umbrella Pine can be propagated through seeds, stem cuttings.
