Bibra Lake Soils

Compost Perth

Organic matter, straight back into the bed.

Mushroom compost, bagged in 30 litres or loose by the cubic metre from our own yard. Compost is the fastest way to put organic matter back into tired soil — it feeds the biology, holds moisture and improves structure as it breaks down.

One thing worth knowing before you buy: mushroom compost is not recommended for acid-loving plants such as azaleas, camellias and rhododendrons, or for some natives. If that is what you are feeding, ask at the counter and we will point you somewhere better.

How much compost do you need?

Work it out before you drive down

Length by width by depth gives you cubic metres. Work it out before you come down and you will not be back tomorrow for a second load.

It is an estimate. Uneven ground and how firmly it settles both change what you actually use, so round up rather than down.

That is about one trailer load. Order a touch over rather than under — a second trip costs more than the extra scoop.

How to choose a compost

Four things that actually decide it

  • What you are feeding

    Mushroom compost suits vegetable gardens, vines, fruit trees and established beds. It does not suit azaleas, camellias, rhododendrons or some natives. That one distinction decides whether this is the right page for you.

  • On top, or dug through

    As a mulch it goes on 50 to 75mm deep and stays clear of the stems. As a conditioner it gets mixed through the soil instead of sitting on the surface. Same bag, different result.

  • Bag or cubic metre

    A 30 litre bag tops up a bed and fits in a boot. Once you are doing a whole garden the bulk compost works out cheaper by volume, and we will load it or deliver it. The changeover point is usually around three or four bags.

  • What it is not

    Compost improves soil that already exists. If the bed is empty you want a soil mix to fill it, then compost to feed it. Buying compost to fill a bed means paying for fertility you cannot use yet.

The bagged one is not the only one

Compost turns up in three places here, because it does three different jobs. If the bag is not the right format or the right material, one of these will be.

Compost pickup and delivery

Collect it, or we will bring it

Collect from the yard

Open seven days at 222 Barrington St, Bibra Lake. The loader puts it straight into your trailer or ute, and someone will tell you whether what you have brought will carry the load you are asking for.

Have it delivered

Across Perth's southern suburbs, seven days. Tell us the address, how much you need and anything awkward about access — tight driveways and low branches change which truck we send. Confirm the current cost when you order.

Compost FAQs

What we get asked at the counter

  • What is mushroom compost?

    It is the substrate mushrooms were grown in, composted a second time and screened. That first life is why it arrives fine textured and well broken down, and why it releases its nutrients into the soil quickly rather than over a season.

  • Which plants should I keep mushroom compost away from?

    Azaleas, camellias and rhododendrons, and some Australian natives. The manufacturer states it plainly and it is worth taking seriously — these are acid-loving plants and mushroom compost does not suit them. Tell us what you are feeding and we will put you on a native mix or a low-phosphorus plant food instead.

  • Can I use compost as a mulch?

    Yes. Lay it 50 to 75mm deep and keep it clear of the stems. It will break down into the soil faster than a wood chip or bark would, so treat it as a feed that also covers rather than a long-lasting surface.

  • What is the difference between compost and a soil conditioner?

    Very little in practice — both are organic matter that improves soil you already have. The clearer distinction is against a soil mix, which fills volume and gives roots something to grow in. If the bed is empty you want the mix first.

  • How much compost do I need?

    Multiply the bed's length by its width by the depth you want, all in metres, and the answer is cubic metres. The calculator on this page does it for you. Bring that number in and we will tell you whether it is bags, a trailer load or a delivery.

  • Do you sell compost in bulk?

    Yes, by the cubic metre. The bulk mushroom compost is a different product to the bagged one, so tell us the job and we will say which one suits it.

  • Can I collect compost myself?

    Yes, seven days. Bags go in a boot. For bulk, the loader puts it straight into your trailer or ute, and if you do not have a trailer you can borrow one of ours free for two hours.

  • Can compost be delivered?

    Yes, across Perth's southern suburbs, seven days. We need the address, the quantity and anything awkward about access. Confirm the current delivery cost when you order, as it varies with distance and quantity.

Tell us the size of the bed

Include your suburb if you want it delivered — it changes the price and whether the big truck can get in. If you are not sure which compost you need, describe the job and we will tell you.
