Mulch does far more than cover the ground. It protects the soil, keeps roots cool and holds moisture, which matters through Perth's long, dry summers.
Why it's worth it
- Cuts down how often you need to water.
- Stops weeds taking hold.
- Adds organic matter as it breaks down.
- Keeps soil temperatures steadier in heatwaves.
How to apply it
- Weed the bed and water it first.
- Spread a layer about 5 to 8 cm deep.
- Keep it a little away from stems and trunks to avoid rot.
- Choose a fine, composted mulch such as a green-waste blend or composted bark. Avoid products that dry into a water-repellent crust.
Keep it topped up
Mulch breaks down over time, which is good for the soil. Check it every few months and top it up to keep the depth.
Regular mulching is one of the simplest ways to keep a Perth garden thriving through the hottest months.
