Jacksonia tarinensis Plant Care

Jacksonia tarinensis (Jacksonia tarinensis) belongs to the Fabaceae family within the Jacksonia genus. Jacksonia tarinensis is native to a small area in the south-west of Western Australia.

Jacksonia tarinensis displays a tall, upright tree growth habit, reaching up to 30 ft tall with a spread of approximately 15 ft. Jacksonia tarinensis produces small, inconspicuous yellow or white flowers.

Leaf size: approximately 6 inches.

Water a young or newly planted Jacksonia tarinensis 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.

Jacksonia tarinensis thrives in full sun.

Jacksonia tarinensis tolerates temperatures of 50–85°F. Jacksonia tarinensis prefers humidity levels of 40–70%.

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

Feed Jacksonia tarinensis 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.

The PlantoScan app can remind you when to water and when to fertilize each plant.

Choose a spot with full sun and well-draining sandy loam with added organic matter. Avoid low spots where water collects after rain.

Jacksonia tarinensis 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.

Jacksonia tarinensis 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 Jacksonia tarinensis 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.

Jacksonia tarinensis 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.

Jacksonia tarinensis can be propagated through seeds, softwood cuttings. Similar propagation techniques also apply to pointed jacksonia plant care, which shares the same genus.

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

Jacksonia tarinensis grows outdoors in USDA Zone 12a. It survives winters down to planting zone 12a. Jacksonia tarinensis is native to a small area in the south-west of Western Australia. In cooler regions, grow Jacksonia tarinensis as a houseplant or bring it indoors before the first frost.
