Western Hay Pea Mulch

Pea straw that feeds the bed as it goes.

Western Hay's Pea Mulch is pea straw in an 80 litre bag weighing 12 kilograms, made at Bindoon on the Great Northern Highway and confirmed non-GMO on Western Hay's own site. It releases nitrogen as it breaks down, which is what has made pea straw a favourite in the vegetable patch.

What Western Hay Pea Mulch suits

What can you use Western Hay Pea Mulch for?

  • Vegetable beds and no-dig gardens

    The classic use, and the reason people ask for pea straw by name. It covers the bed and feeds it at the same time, which suits a patch that is being cropped hard.

  • Strawberries and low fruit

    Straw lifts the fruit off the soil, which keeps it cleaner and slows the rot that comes from sitting on wet ground.

  • Beds that want nitrogen

    It releases nitrogen as it breaks down, so it is doing a second job while it does the first. A raw straw or a bark takes nitrogen instead of giving it.

  • Sloped beds where runoff cuts channels

    Straw knits together, and on a slope that is an advantage — it holds soil in place where a loose chip would wash to the bottom.

How much Pea Mulch do you need?

Buy on depth, not on the headline

Western Hay put a bag at up to 18 square metres. That figure is a very thin spread, and it is not the depth they recommend anywhere else on their own site.

Both numbers below are theirs. We would rather print the one that sends you home with enough mulch than the one that reads better.

At this depthOne 80 litre bag doesWhat it is for
Western Hay's headlineUp to 18m²A very thin scatter. It will not block the light to germinating weed seed.
5 to 7cm, as recommendedCloser to 1.5m²The depth that actually suppresses weeds and holds moisture. Buy on this one.
Topping up mid-seasonTwo to three times furtherA top-up is a thin layer over what is already there, so a bag goes much further.

Keep it off the stems and trunks — straw held against a stem holds moisture there and promotes rot. Store the bag somewhere cool and dry until you get to it.

Western Hay Pea Mulch in Perth

Matting, drippers and Perth sand

Most Perth gardens water on a roster rather than by hand, so the water arrives on two or three fixed days and it has to count. A mulch that has matted into a crust sheds that water sideways instead of letting it through.

Perth sand compounds it. Once the surface has dried hard it goes water repellent, and water that cannot get through the mulch will not soak in at all — it runs to the low corner of the bed and sits there.

None of that makes pea straw the wrong choice. It makes it a choice with a maintenance step: run a rake through the layer when you notice water sitting on it, and it takes water again. If you would rather not think about it, that is what the sugar cane is for.

Why Western Hay Pea Mulch

Why choose Western Hay Pea Mulch?

  • It feeds while it covers

    Nitrogen released as it breaks down, which is the difference between a mulch that only shades the soil and one that improves it. That is why it has been the vegetable gardener's default for decades.

  • A published composition

    90% organic matter, crude fibre at 15%, moisture at 12%, pH 6.0. Western Hay put the numbers on their own site rather than leaving it at organic.

  • Confirmed non-GMO

    Stated by Western Hay themselves. Worth knowing if you are growing food and it matters to you what went into the paddock.

  • Made an hour up the road

    Bindoon, on the Great Northern Highway. Western Australian, and not trucked across the country to get here.

Using Western Hay Pea Mulch

How to use Western Hay Pea Mulch

  1. Water the bed first

    Mulch laid over dry Perth sand keeps it dry. Get the soil properly wet through before you cover it, or the layer works against you for the first month.

  2. Spread it 5 to 7cm deep

    That is Western Hay's figure. Keep it off the stems and trunks — straw held against a stem holds moisture there and promotes rot, which is the one mistake that actually kills plants.

  3. Rake it if water starts sitting on top

    It mats down when wet, more than sugar cane does. If you find water pooling on the surface rather than soaking through, lift the layer with a rake and it will take water again.

  4. Top it up two or three times a year

    Pea straw breaks down faster than the woody mulches, which is the price of it feeding the bed. Expect to top up rather than replace.

When to choose something else

When it is the wrong product

  • It mats down when wet, more than sugar cane does. If your beds are on drippers and you have had water sitting on top of a mulch layer before, Sugar Cane Mulch is the one that stays open.
  • Western Hay make no weed-seed-free claim for this product, so we are not going to make one for them. If a guaranteed weed-free mulch is what you are after, the pasteurised Lupin Mulch is the one to ask about.
  • It breaks down quickly, at 2 to 3 months against 4 to 6 for sugar cane. That is a feature in a vegetable bed and a nuisance on a verge.
  • It is not a decorative mulch. It looks like straw, because it is straw. For a front garden where the finish matters, the coloured mulches are what that job wants.

What people say

Western Hay Pea Mulch questions

Western Hay Pea Mulch FAQs

  • Does pea mulch feed the garden?

    Yes. Peas are a legume, so pea straw carries nitrogen and releases it into the bed as it breaks down rather than borrowing from the soil the way a woody mulch does. That is the reason it has been the vegetable gardener's default for decades.

  • How much does an 80 litre bag cover?

    Western Hay say up to 18 square metres, but that is a very thin spread. At the 5 to 7cm they also recommend around plants, expect a bag to do closer to a square metre and a half. Buy on the depth rather than on the headline figure.

  • Does pea mulch have weed seeds in it?

    Western Hay make no weed-seed-free claim for this product, so we are not going to make one for them. If a guaranteed weed-free mulch is what you need, ask about the pasteurised Lupin Mulch, where the seed is killed in processing.

  • Why does water sit on top of my pea straw?

    It has matted. Pea straw knits into a crust when it gets wet, more than sugar cane does, and the crust sheds water sideways. Lift the layer with a rake and it will take water again. If you would rather not think about it, Sugar Cane Mulch stays open when wet.

  • Is pea mulch or sugar cane mulch better?

    They answer different questions. Pea feeds the bed and mats down; sugar cane does not feed but stays open and lasts twice as long. If your beds are on drippers, take the sugar cane. If you want the mulch doing a feeding job as well, take the pea.

  • How deep should I spread pea mulch?

    Five to seven centimetres around plants, kept clear of the stems and trunks. Straw held against a stem holds moisture there and promotes rot, which is the one mulching mistake that actually kills plants.

  • Can I collect it myself?

    Yes, seven days. The bags go straight in a boot, so you do not need a trailer for a few of them.

  • Can pea mulch be delivered?

    Yes, across Perth's southern suburbs. Tell us how many bags and the address, and confirm the current delivery cost when you order.
