About Your New Acacia pycnantha - Golden Wattle

Acacia pycnantha is Australia's official floral emblem, and the reason is obvious in late winter when the tree disappears under masses of large fragrant golden ball flowers. It is the wattle behind Wattle Day and the green and gold of national sporting colours.

The Golden Wattle grows very fast at 1 to 2 metres per year, reaching 4 to 8 metres tall and 3 to 6 metres wide with an open spreading habit and broad sickle-shaped foliage. It is used for quick screening, rural shelter, revegetation and as a fast feature tree while slower species establish.

This Australian native tolerates light to moderate frost once established, along with poor sandy soils and extended dry. It grows in full sun and, like most fast wattles, is relatively short-lived at 15 to 20 years.

Frequently Asked Questions

About Acacia pycnantha

Is Acacia pycnantha Australia's floral emblem?

Yes. Acacia pycnantha was formally proclaimed Australia's national floral emblem in 1988, and its flowering is marked by National Wattle Day on 1 September.

How big does the Golden Wattle grow?

It reaches 4 to 8 metres tall and 3 to 6 metres wide with an open spreading habit. It is a small to medium tree suited to most gardens and rural properties.

How fast does Acacia pycnantha grow?

Very fast, at 1 to 2 metres per year in good conditions. It delivers a usable screen or feature tree within two years of planting.

When does the Golden Wattle flower?

Masses of large fragrant golden ball flowers appear through late winter and early spring, typically August and September, which is why Wattle Day falls on 1 September.

How long does Acacia pycnantha live?

Like most fast-growing wattles it is relatively short-lived at 15 to 20 years. Plan for replacement, or use it as a nurse crop for slower long-term plantings.

Is it frost tolerant?

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

How far apart should I plant it?

Plant 2 to 3 metres apart for a fast screen or shelterbelt, or 4 to 5 metres apart as individual feature trees.

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.

Planting: Position level with the surrounding soil, backfill gently, firm in, then water deeply to settle the roots.

Recommended Planting Spacing For Your Acacia pycnantha - Golden Wattle

Hedging and screening: 1 to 1.5 metres apart for a dense informal screen, or 80 centimetres apart for a tighter formal hedge.

Feature tree: 3 to 4 metres apart to allow the full canopy and form to develop.

Long Term Care For Your Acacia pycnantha - Golden 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: Tip prune in late winter and again in summer to build dense growth. For a formal hedge, light shaping two to three times a year keeps lines crisp.

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.
