As we move toward the tail end of summer, weeds seem to appear overnight. The instinct for many gardeners is to reach for a spray bottle. But in most home gardens, there’s a better, less expensive and long-term solution — mulch.
A thick layer of quality mulch (75–100mm) suppresses weeds by blocking sunlight, regulates soil temperature, and improves moisture retention. Even better, organic mulch breaks down over time, feeding your soil and improving structure. Turning prunings and garden waste into mulch is one of the most cost-effective and environmentally responsible weed control methods available.
By contrast, rock and weed mat can create problems. Rocks absorb and radiate heat, stressing plants in summer, while weed mat often becomes clogged with soil and organic matter — and eventually weeds grow on top of it anyway. Chemicals may provide a quick fix, but they don’t improve soil health and repeated use can create longer-term issues.
On the lawn, the same “work with nature” principle applies. Catching clippings gives a tidy finish, particularly if the lawn has grown long. But for regular maintenance mowing, mulching is often the smarter option. Fine clippings break down quickly, returning nutrients to the soil and reducing fertiliser needs.
Healthy soil grows stronger plants. And stronger plants leave less room for weeds.
