What Is the Hooked Wattle?
Hooked Wattle (Acacia adunca) belongs to the Fabaceae family within the Acacia genus. Hooked Wattle is native to eastern Australia.
Hooked Wattle displays a tall, spreading tree growth habit, reaching up to 30 ft tall with a spread of approximately 20 ft. Hooked Wattle produces clusters of small yellow or white flowers.
Leaf size: approximately 4 inches.
How Often Should You Water a Hooked Wattle?
Water a young or newly planted Hooked Wattle 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.

What Soil Mix Works Best for a Hooked Wattle?
Well-draining sandy soil mix with some organic matter. Good drainage is essential for Hooked Wattle to prevent waterlogging, which leads to root rot and fungal issues.
How Often Should You Fertilize a Hooked Wattle?
Feed Hooked Wattle every 8 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.
Where Should You Plant a Hooked Wattle?
Choose a spot with full sun and well-draining sandy soil mix with some organic matter. Avoid low spots where water collects after rain.
Hooked Wattle is suited to USDA Zone 8b – 11a.
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 Hooked Wattle?
Hooked Wattle can spread to about 20 ft (6.1 m) and reach about 30 ft (9 m) tall. Space plants about 20 ft (6.1 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 Hooked Wattle?
Prune Hooked Wattle 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.
How Do You Care for a Hooked Wattle in Winter?
Hooked Wattle is hardy down to USDA zone 8b, so once established it can stay outdoors through winter in that zone and warmer ones.
Water deeply in late autumn before the ground freezes, and spread a 5–8 cm (2–3 in) layer of mulch over the root zone, keeping it away from the trunk.
Young and container-grown trees need extra protection: roots in a pot freeze much more easily than roots in the ground.
How Do You Propagate a Hooked Wattle?
Hooked Wattle can be propagated through seeds, cuttings. Similar propagation techniques also apply to gold dust wattle plant care, which shares the same genus.
Is the Hooked Wattle Toxic to Pets and Children?
Pet safety not verified
The ASPCA does not list Hooked Wattle, so we can't confirm whether it is safe for cats and dogs. Keep pets from chewing it as a precaution.
This is a general caution, not veterinary or medical advice. If your pet ate a plant, contact your vet or animal poison control.
