Premium Black Mulch

• 

  Front gardens and verges

  Where the bed is seen from the street and the finish is half the point. Black reads as deliberate and modern, and it makes green foliage look greener by contrast.

• 

  Formal and architectural planting

  A uniform dark ground under structured planting. It is the mulch that looks designed rather than natural, which is exactly right for some gardens and wrong for others.

• 

  Beds you want warmed in early spring

  Black absorbs heat, so the soil under it warms sooner. On a bed you are trying to get moving after winter, that is a small genuine advantage.

• 

  Anywhere grey mulch has annoyed you before

  If you have mulched a front bed and watched it fade to grey by February, this is the product that problem is solved by.

An untreated wood chip greys off under UV, and Perth delivers more of it than almost anywhere a mulch gets sold. A bed mulched in October can look tired by February, which is the whole reason colour-injected mulches exist in this market.

The trade-off runs the other way in the same summer. Black absorbs heat rather than reflecting it, so on a north or west-facing bed against a wall the surface gets genuinely hot — worth thinking about for shallow-rooted plants that are already struggling in that spot.

If the bed is baking already, the answer is usually a lighter or natural mulch and a deeper layer, rather than a darker one. Ask at the counter and describe the aspect.

• Will black mulch fade?+

  Far less than an untreated chip. The colour is injected through the piece rather than sprayed on the surface, and it is made with high UV resistance specifically because a Perth summer greys off an ordinary wood chip within a season.

• Does black mulch make the soil too hot?+

  It absorbs heat rather than reflecting it, so a black-mulched bed runs warmer. That helps get a bed moving in early spring and it is worth thinking about on a north or west-facing bed against a wall in February. Describe the aspect at the counter and we will tell you honestly.

• Is the colour safe for plants?+

  It is a colour-injected bark and wood product made for garden use. If you want the specifics of the colourant for a particular reason, ask and we will get them from the supplier rather than guessing at them here.

• Does black mulch still suppress weeds?+

  Yes. It is bark and wood underneath the colour, so it does everything a mulch does — blocks light to weed seed, holds moisture and insulates the roots. The colour is on top of that, not instead of it.

• Black or red?+

  It is a decision about the house rather than the plants. Black recedes and makes the foliage the subject, which suits modern and formal gardens. Red comes forward and pairs with warm brick and stone. Black also runs the hotter of the two.

• How deep should I spread it?+

  Fifty to seventy-five millimetres, evenly, kept clear of stems and trunks. Even coverage matters more with a decorative mulch than with any other, because a thin patch shows the soil through.

• How much do I need?+

  Length by width by depth in metres gives you cubic metres, and the calculator on this page does the arithmetic. Bring the number down and we will tell you whether it is a trailer load, a bulka bag or a truck.

• Can Premium Black Mulch be delivered?+

  Yes, across Perth's southern suburbs, seven days. Tell us the address, how much you need and anything awkward about access. Confirm the current delivery cost when you order.
