Aussie Organic Mushroom Compost
Composted once already. Ready fast.
This is 100% genuine spent mushroom farm compost, bagged in 30 litres by Aussie Organics Garden Supplies at Serpentine, who have been doing it since 1994. It has already been composted once to grow mushrooms in, so it arrives fine textured, well broken down and quick to release its nutrients. Not for azaleas, camellias or rhododendrons.

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 Organic Mushroom Compost suits
What can you use Aussie Organic Mushroom Compost for?
Vegetable gardens
Dug through before planting. Fast-breaking compost suits an annual bed, where the crop is only there for a season and needs the feed now.
Vineyards and fruit trees
Listed on the client's own use list. Spread out from the trunk and either mulched over or worked lightly into the surface.
Established beds needing a lift
Topping up soil that has gone tired before a new planting, rather than replacing it. It restores structure and organic matter together.
As a mulch, 50 to 75mm
One of the three uses on the pack. Keep it clear of the stems, the same as any mulch.
How many bags?
Depends whether you are mulching or digging
Mushroom compost has two depths, because the pack has two uses. As a mulch it goes on 50 to 75mm; as a conditioner it is dug through the top of the soil and goes much further.
Thirty litres is 0.03 of a cubic metre, so the arithmetic is simple once you know which of the two you are doing.
| Use | Depth | What a 30L bag does |
|---|---|---|
| As a mulch | 50 to 75mm | About 0.5m² at 60mm. Mulching a bed takes a lot of bags. |
| As a soil conditioner | Dug through the top 100mm | About 1.5m², depending how rich you want the bed. |
| Potting mix additive | A proportion of the mix | A component, not the whole pot. Ask us for a ratio. |
Not recommended for azaleas, camellias, rhododendrons or some natives. And garden composts contain micro-organisms — gloves, keep it damp, wash your hands afterwards.
Why Aussie Organic Mushroom Compost
Why choose Aussie Organic Mushroom Compost?
100% genuine, not a blend
Spent mushroom compost, not a general compost with some mushroom compost in it. What the bag says is what is in it.
It breaks down quickly
Already composted once, so the nutrients reach the plant sooner than they would from a coarse compost that is still working.
It holds water in sand
Up to 65 per cent of its own weight, by the client's figure. On free-draining Perth sand that is worth as much as the feed.
Mulch or conditioner, your choice
Spread it on top or dig it through. The pack lists both, plus use as a potting mix additive.

Using Aussie Organic Mushroom Compost
How to use Aussie Organic Mushroom Compost
Decide whether it is a mulch or a conditioner
As a mulch, lay it 50 to 75mm deep and keep it clear of the stems. As a soil conditioner, mix it through the soil rather than leaving it sitting on the surface. The pack supports both.
Check what is planted there
It is not recommended for some native plants or for acid-loving plants such as azaleas, camellias and rhododendrons. If those are what you are planting, ask us for a native mix instead.
Water it in
Compost that dries out on the surface can shed water rather than take it. Wetting it once it is down gets it working and keeps it there.
Use it in potting mix sparingly
The pack lists it as a potting mix additive, which means a component rather than the mix itself. A proportion through a mix, not a pot filled with it.
When to choose something else
When it is the wrong product
- Not recommended for some native plants or acid-loving plants such as azaleas, camellias and rhododendrons. Ask us for a native mix if that is the bed you are filling.
- It is a conditioner and a feed, not a soil. It improves a bed; it does not fill one.
- The 65 per cent water figure is the client's, not a reading off the bag — the pack's fine print is not legible in the photograph we have, so we have attributed it rather than presented it as printed.
- Past a few beds it is worth pricing the bulk mushroom compost by the cubic metre. It is a different blend, so ask us which suits the job before you switch.
- Garden composts contain micro-organisms. Wear gloves, keep the product damp while you handle it, and wash your hands afterwards.
