Aussie Organics Premium Soil Conditioner
Carbon, in the one place Perth soil has none.
Mature compost in a 30 litre bag, with a wetting agent and trace elements blended through it. Aussie Organics call it a blend of selected well composted materials, rich in organic carbon that works like a sponge, storing water and nutrients. It is a conditioner, not a fertiliser.

Real stock, not a swatch. Blended products vary a little batch to batch, so treat these as a guide rather than an exact colour match.

What Aussie Organics Premium Soil Conditioner suits
What can you use Aussie Organics Premium Soil Conditioner for?
Digging through a new bed
The best time to do it, because you can get it through the whole root zone rather than working around established plants.
Vegetable gardens
Veggie beds are worked hard and lose organic matter fastest. This goes back in between crops.
Around established shrubs and trees
Spread out to the drip line and lightly forked in, keeping it off the trunk.
Sand that has stopped taking water
The wetting agent is in the bag for exactly this — the dry patch where water beads up and runs off sideways.
How many bags?
30 litres, and what it improves
Conditioner is sold by volume, so the sum is area times the depth you are spreading before you dig it in.
There is no published rate for this bag, so the rows below are arithmetic at named depths. For a specific bed, ask at the counter.
| Job | Spread depth | What a 30 litre bag does |
|---|---|---|
| Improving an existing bed | 25mm | About 1.2 square metres. |
| A new bed, dug through | 50mm | About 0.6 square metres. |
| Around an established tree | Light, to the drip line | One bag per small tree, kept off the trunk. |
| More than a couple of beds | Bulk | Thirty-three bags to the cubic metre — ask about bulk conditioner. |
Doing it every year matters more than doing it thickly once. Organic matter in Perth sand is a subscription, not a purchase.
Aussie Organics Premium Soil Conditioner in Perth
Why sand needs this every year
Organic matter breaks down faster in warm sandy soil than in almost any other ground, and Perth gives it warmth, air and drainage all at once. A bed conditioned in autumn will have lost much of it by the following summer.
That is not a fault in the product, it is the nature of sand. The way through is both halves: compost or conditioner each year for the biology, and a clay once for the mineral structure that does not break down.
Why Aussie Organics Premium Soil Conditioner
Why choose Aussie Organics Premium Soil Conditioner?
Mature, not raw
Raw compost keeps composting in your bed and borrows nitrogen from the plants while it does. Mature material is finished, so it feeds instead of competing.
Organic carbon is the whole point
It is what holds water and nutrients in the root zone. Nothing else in a bag does that job, and Perth sand starts with almost none.
Wetting agent through the bag
Compost alone will not rewet a hydrophobic patch quickly. The wetter gets the water in so the compost can hold it.
Trace elements included
The minor nutrients that nobody thinks about until a plant goes yellow between the veins.

Using Aussie Organics Premium Soil Conditioner
How to use Aussie Organics Premium Soil Conditioner
Get it into the top 100 to 150mm
Spread it and turn it in. A conditioner left lying on the surface dries out and does nothing for roots that are 150mm down.
Wet the ground first if it is repelling water
On a bad dry patch, water it, let it sit, water again. Digging conditioner into ground that water cannot enter puts it somewhere it cannot work.
Around established plants, stay shallow
Fork it into the top of the soil out at the drip line rather than digging near the trunk. Most feeder roots are further out than people expect.
Mulch over the top
Bare improved soil dries out and oxidises in a Perth summer. Mulch keeps the work you just did.
When to choose something else
When it is the wrong product
- It is not a fertiliser. If a plant is hungry right now, a manure or a fertiliser feeds it — this changes what the soil can hold.
- It is not permanent. Organic matter breaks down and has to be topped up, which is the difference between this and a clay such as bentonite or Soil Solver.
- Aussie Organics publish no application rate. The figure on this page is arithmetic on 30 litres at a stated depth, not a recommendation.
- For more than a couple of beds, bulk soil conditioner by the cubic metre is far cheaper. It is a different product to this bag, so ask which one suits.
- The pack carries a health warning: garden soils contain micro-organisms that may be harmful. Gloves, keep it damp while you work, do not breathe it in, wash your hands afterwards.
