Mulch

Mulch is one of the simplest ways to improve your garden. A layer of mulch suppresses weeds, holds moisture in the soil, and breaks down over time to feed the ground underneath.

We carry a range of mulch types including bark mulch, sugar cane, pea straw, pine bark, and recycled timber mulch. We sell both bagged and bulk quantities, and can help you work out how much you need.

A 5u201310cm layer of mulch is ideal for most garden beds. Spread it evenly around plants but keep it away from stems and trunks to prevent collar rot. Top up mulch annually as it breaks down.

Different mulch types suit different situations. Fine bark mulch looks neat in formal garden beds. Sugar cane and pea straw break down faster and are good for veggie gardens. Pine bark is long-lasting and works well around acid-loving plants like camellias and azaleas.

Melbourne’s hot, dry summers make mulching especially important. Unmulched soil can lose moisture several times faster than mulched soil, which means more watering and more stressed plants.

Mulch

Did You Know?

Mulch is one of the best investments you can make in your garden. Here are a few things worth knowing:

  • Mulch can reduce your watering needs by up to 70%. By shading the soil surface and reducing evaporation, a good layer of mulch keeps moisture where plants need it. This is particularly valuable during Melbourne’s water restrictions in summer.
  • Fresh wood chip mulch can temporarily rob nitrogen from the soil. As fresh wood breaks down, the microbes doing the work use nitrogen from the soil. This is temporary and only affects the surface layer, but you can offset it by adding a nitrogen-rich fertiliser when mulching.
  • Piling mulch against tree trunks causes collar rot. Always leave a 10u201315cm gap between mulch and the base of trees and shrubs. Moisture trapped against the trunk creates conditions for fungal diseases that can kill plants.
