Orange Firethorn Plant Care

Orange Firethorn (Pyracantha angustifolia) belongs to the Rosaceae family within the Pyracantha genus. Orange Firethorn is native to China. Orange Firethorn is also known as Chinese Firethorn.

Orange Firethorn displays an upright, dense shrub growth habit, reaching up to 10 ft tall with a spread of approximately 8 ft. Orange Firethorn produces clusters of small white flowers in spring, followed by orange to red berries.

Leaf size: approximately 2 inches.

Water a young or newly planted Orange Firethorn 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.

Orange Firethorn thrives in full sun to partial shade.

Pyracantha angustifolia tolerates temperatures of 50–85°F. Orange Firethorn prefers humidity levels of 40–70%.

Well-draining loamy soil with added compost for nutrients. Good drainage is essential for Orange Firethorn to prevent waterlogging, which leads to root rot and fungal issues.

Feed Orange Firethorn 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 loamy soil with added compost for nutrients. Avoid low spots where water collects after rain.

Orange Firethorn 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.

Orange Firethorn can spread to about 8 ft (2.4 m) and reach about 10 ft (3 m) tall. Space plants about 8 ft (2.4 m) apart so mature crowns don't crowd each other, and plant at least half that distance from buildings, fences and paths.

Prune Orange Firethorn 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.

Orange Firethorn 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.

Orange Firethorn can be propagated through softwood cuttings, hardwood cuttings. Similar propagation techniques also apply to firethorn plant care, which shares the same genus.
