About Your New Acacia acinacea - Golden Dust Wattle

Acacia acinacea is smothered in masses of bright golden ball-shaped flowers each spring, carried along arching branches of fine blue-green foliage so densely that the whole plant appears dusted in gold. That display is where the common name Gold Dust Wattle comes from.

Acacia acinacea is compact, growing to 1 to 3 metres tall and 1 to 2 metres wide at 30 to 60 centimetres per year with a graceful arching habit. That modest scale makes it one of the few wattles that suits a suburban garden bed, a low informal screen, or mass planting along a rural fence line.

This Australian native tolerates light to moderate frost once established, along with poor sandy soils, drought and part shade. It grows in full sun to part shade and, like all wattles, needs low-phosphorus feeding and free drainage.

Frequently Asked Questions

About Acacia acinacea

How big does Acacia acinacea grow?

The Gold Dust Wattle grows to 1 to 3 metres tall and 1 to 2 metres wide with an arching habit. It is one of the more compact wattles and suits suburban gardens.

When does Acacia acinacea flower?

Masses of golden ball-shaped flowers appear through spring and into summer, carried so densely along the branches that the plant appears dusted in gold.

Is Acacia acinacea an Australian native?

Yes. It is native to south-eastern Australia and is widely used in revegetation and habitat planting as well as in gardens.

Does it attract wildlife?

Yes. The flowers attract native bees, butterflies and other pollinators, and the dense fine branching provides shelter for small birds.

Can it be used as a hedge or screen?

Yes. Plant 1 to 1.5 metres apart for a low informal screen. Its arching habit gives a softer, looser line than a formally clipped hedge.

Is Acacia acinacea frost tolerant?

It handles light to moderate frost once established. Protect young plants through their first winter in colder inland districts.

What feeding does it need?

Use only low-phosphorus native fertiliser. Like all wattles it is damaged by high-phosphorus formulations, and it also requires free-draining soil.

Enriched Planting Mix (AO Certified)

$21.95

Enriched Planting Mix is a certified organic blend of Pure Magic Compost, composted animal manure, gypsum, composted coarse bark and a wetting agent, bagged in 30L. It is built to be dug through existing garden soil at planting time rather than used on its own, and the gypsum is what sets it apart from a plain compost.

Gypsum helps break up heavy clay so water and roots can move through it, while the compost and manure return organic matter and nutrient to tired ground. The coarse bark holds structure and keeps air around the root zone, and the wetting agent keeps moisture in the soil longer after rain or watering.

Use it when planting trees, shrubs, roses, fruit trees and exotic garden plants, particularly into clay. Dig a hole twice the width of the pot and 7 centimetres deeper, then mix roughly one third planting mix through the excavated soil. Spread 7 centimetres of that improved soil in the base before setting the plant in.

Frequently Asked Questions

About Enriched Planting Mix

What is Enriched Planting Mix made from?

It is a blend of Pure Magic Compost, composted animal manure, gypsum, composted coarse bark and a wetting agent. Each part has a job. The compost and manure supply organic matter and nutrient, the gypsum works on clay structure, the bark keeps air around the roots and the wetting agent holds moisture in the soil.

What plants is it suitable for?

It suits exotic garden plants, including roses, ornamental and deciduous trees, fruit trees, shrubs and perennials, and it earns its keep most on heavy clay sites. It is a planting mix rather than a potting mix, so its job is improving soil at planting time. Phosphorus sensitive natives are the one clear exception.

Is it safe for natives?

No, not for the phosphorus sensitive ones. The composted animal manure in this blend lifts phosphorus well above what Proteaceae such as Banksia, Grevillea, Hakea and Protea will tolerate, and the result can be leaf burn, dieback and plant death. Use the Native Potting Mix for those species, or plant them into unimproved local soil.

Is it certified organic?

Yes. It is a certified organic product with no chemical additives, which is why the manure and compost in it are fully composted rather than raw. That makes it sound around fruit trees and vegetable beds, and it means you are adding genuine organic matter to your soil rather than a synthetic conditioner.

How much do I need?

Work on roughly one third planting mix to two thirds of the soil you dug out of the hole. For a shrub out of a 200 millimetre pot that is only a few litres. An advanced tree going into a large hole will take considerably more. Judge the quantity by the volume of the hole rather than the size of the plant.

Can I use it in pots?

It is not a potting mix and should not be used on its own in a container. The blend is designed to be diluted through garden soil, and used straight in a pot it holds too much water and settles badly. For containers, reach for a premium potting mix, or the native mix if you are potting natives.

Does it need to be watered in?

Yes. Water the plant well several hours before you plant it, then water thoroughly again once the hole is backfilled and the soil firmed down. That first deep watering settles the improved soil around the root ball and drives out air pockets. Keep the water up over the first few months while the roots establish.

Long Term Care For Your Acacia acinacea - Golden Dust Wattle

Watering: Water deeply twice weekly through the first 12 months. Once established, this is drought tolerant and only needs a deep soak during extended dry periods.

Mulching: Apply a 5 to 7 centimetre layer of organic mulch over the root zone, keeping it 5 centimetres clear of the trunk.

Pruning: Minimal pruning required. Light tip prune in late winter to maintain shape, and remove lower branches as the tree grows to develop a clean feature trunk.

Fertilising: Apply a slow-release native blend in early spring and again in autumn. Avoid high-phosphorus formulations as a precaution.

Pest and disease: Hardy against most pests and diseases. Occasional inspection in warm humid conditions is all that's needed.
