Sticky Boobialla Plant Care

Sticky Boobialla (Myoporum viscosum) belongs to the Scrophulariaceae family within the Myoporum genus. Sticky Boobialla is native to South Australia. Sticky Boobialla is also known as Viscid Boobialla.

Sticky Boobialla displays an upright, spreading shrub growth habit, reaching up to 4 ft tall with a spread of approximately 6 ft. Sticky Boobialla produces small white or pink star-shaped flowers.

Leaf size: approximately 2 inches.

Water a young or newly planted Sticky Boobialla every 7–14 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.

Sticky Boobialla thrives in full sun to partial shade.

Myoporum viscosum tolerates temperatures of 50–85°F. Sticky Boobialla prefers humidity levels of 40–70%.

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

Feed Sticky Boobialla 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 sandy loam with added organic matter. Avoid low spots where water collects after rain.

Sticky Boobialla 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.

Sticky Boobialla can spread to about 6 ft (1.8 m) and reach about 4 ft (1 m) tall. Space plants about 6 ft (1.8 m) apart so mature crowns don't crowd each other, and plant at least half that distance from buildings, fences and paths.

Prune Sticky Boobialla 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.

Sticky Boobialla 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.

Sticky Boobialla can be propagated through softwood cuttings, seeds. Similar propagation techniques also apply to mallee boobialla plant care, which shares the same genus.

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

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