Baeckea pentagonantha Plant Care

Baeckea pentagonantha (Baeckea pentagonantha) belongs to the Myrtaceae family within the Baeckea genus. Baeckea pentagonantha is native to near-coastal areas in the west of Western Australia.

Baeckea pentagonantha displays a compact, low-growing shrub growth habit, reaching up to 2 ft tall with a spread of approximately 3 ft. Baeckea pentagonantha produces small white or pink flowers in clusters.

Leaf size: approximately 1.5 inches.

Water a young or newly planted Baeckea pentagonantha every 7–10 days, soaking the whole root zone, until it is established — usually one to two growing seasons. Established shrubs mainly need water during long dry spells. In a container, water whenever the top few centimetres of soil are dry.

Baeckea pentagonantha thrives in full sun to partial shade.

Baeckea pentagonantha tolerates temperatures of 50–80°F. Baeckea pentagonantha prefers humidity levels of 40–70%.

Well-draining acidic soil mix with peat moss and perlite. Good drainage is essential for Baeckea pentagonantha to prevent waterlogging, which leads to root rot and fungal issues.

Feed Baeckea pentagonantha every 6 months during the growing season with a balanced, slow-release fertilizer at the rate on the label. Established shrubs 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 acidic soil mix with peat moss and perlite. Avoid low spots where water collects after rain.

Baeckea pentagonantha is suited to USDA Zone 12a.

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

Baeckea pentagonantha can spread to about 3 ft (0.9 m) and reach about 2 ft (1 m) tall. Space plants about 3 ft (0.9 m) apart so mature crowns don't crowd each other, and plant at least half that distance from buildings, fences and paths.

Prune Baeckea pentagonantha 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 shrub in one year.

Baeckea pentagonantha 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.

Baeckea pentagonantha can be propagated through softwood cuttings, seeds. Similar propagation techniques also apply to chinese rosemary plant care, which shares the same genus.
