What Soil Mix Works Best for a Taurine Mallee?
Well-draining sandy loam with some organic matter. Good drainage is essential for Taurine Mallee to prevent waterlogging, which leads to root rot and fungal issues.
How Often Should You Fertilize a Taurine Mallee?
Feed Taurine Mallee 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.

Where Should You Plant a Taurine Mallee?
Choose a spot with full sun and well-draining sandy loam with some organic matter. Avoid low spots where water collects after rain.
Taurine Mallee 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.
How Far Apart Should You Plant a Taurine Mallee?
Taurine Mallee can spread to about 50 ft (15.2 m) and reach about 100 ft (30 m) tall. Space plants about 50 ft (15.2 m) apart so mature crowns don't crowd each other, and plant at least half that distance from buildings, fences and paths.

How Do You Prune a Taurine Mallee?
Prune Taurine Mallee 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.
