How to Protect Your Garden From the Perth Summer Heat with Murray River Mulch

If you’ve lived through a Perth summer, you already know our gardens can have a pretty rough time.

Long stretches of hot weather, intense afternoon sun, dry soil and those inevitable 40°C days can quickly take their toll on lawns, garden beds and plants. Even a garden that looks healthy heading into summer can begin struggling once the serious heat arrives.

The good news? Preparing your garden before summer hits can make a huge difference.

Now is the time to check your irrigation, get on top of weeds, prepare your plants and, importantly, get your garden beds mulched before the serious heat arrives.

Mulch Before Summer Arrives

If mulching the garden has been sitting on the to-do list, now is the time to get it done.

Mulch creates a protective layer over the soil, helping shield it from direct sunlight and reducing how quickly moisture is lost during hot, dry weather.

During a Perth summer, when garden beds can spend hours baking in the sun, that extra protection can make a real difference.

Rather than waiting until your soil is already dry and your plants are struggling, get your mulch down before the hottest weather arrives.

It gives your garden a protective layer heading into summer and can make maintaining moisture through the hotter months much easier.

And as an added bonus, freshly mulched garden beds look pretty good too.

Protect the garden AND give it a glow-up. We call that a win.

Protect Your Soil From the Sun

When we think about protecting a garden from heat, we usually focus on the plants.

But the soil underneath them needs protection too.

Bare soil is directly exposed to the sun, causing the surface to heat up and moisture to disappear much faster.

Covering exposed garden beds with mulch creates a barrier between the soil and the harsh summer sun, helping maintain a more protected environment around your plants' root systems.

Basically, if you wouldn't want to stand barefoot on it in the middle of a Perth summer, your garden probably doesn't want to either.

Water Smarter, Not Just More

When temperatures start climbing, the answer isn't necessarily to constantly throw more water at the garden.

How and when you water matters too.

Deep watering encourages plants to develop stronger root systems further below the soil surface, where conditions are generally more stable.

Where possible, watering earlier in the day also gives moisture an opportunity to soak into the soil before the hottest part of the day arrives.

It's also worth checking your irrigation system now rather than discovering a problem during the first heatwave.

Check sprinklers, drippers and irrigation lines to make sure water is actually reaching the areas it's supposed to.

Help Your Garden Hold Onto Water

Watering is only half the battle during summer. You also want to help your soil hold onto that moisture.

This is another reason getting your mulch down before summer is so worthwhile.

By covering the soil surface, mulch can help reduce evaporation and keep moisture available within the soil for longer.

It doesn't mean you can forget about watering altogether — unfortunately, mulch isn't that magical — but it can help the water you're already putting into your garden work more effectively.

Give Sensitive Plants Some Shade

Not every plant loves spending the afternoon getting absolutely roasted by the Perth sun.

Young plants, recently transplanted gardens and more delicate varieties can be particularly vulnerable during periods of extreme heat.

Temporary shade cloth can provide additional protection during particularly hot conditions.

Pay special attention to areas receiving harsh western afternoon sun, as these parts of the garden can take an absolute beating during summer.

Keep On Top of Weeds

Your plants aren't the only things competing for the moisture in your soil.

Weeds are also taking advantage of the water and nutrients available throughout your garden beds.

Removing weeds before summer reduces that competition and means more of the available moisture can go towards the plants you actually want growing there.

Mulching your garden beds can also help suppress new weed growth by limiting the sunlight reaching the soil surface.

Because somehow, when every other plant in the garden is struggling through summer, the weeds still seem to be having the time of their lives.

Don't Forget Your Potted Plants

Pots can be particularly vulnerable during Perth summers.

The smaller amount of soil within a pot can dry out much faster than an established garden bed, particularly when the pot is exposed to direct sunlight.

Move sensitive pots somewhere with afternoon shade where possible and check their moisture levels regularly during periods of hot weather.

Also consider what's surrounding the pot. Hot paving, concrete and walls can continue radiating heat even after the sun has moved.

Watch for Signs Your Garden Is Struggling

Your garden will usually give you a few warning signs when it's having a hard time.

Wilting, curling leaves, scorched or brown edges, premature leaf drop and extremely dry soil can all indicate heat stress.

Check your garden regularly during particularly hot periods so you can identify problems early.

Pay extra attention to new plants and recently established garden beds, which may need a little more help getting through their first summer.

Don't Wait for the First 40°C Day

The best time to prepare your garden for summer is before summer becomes a problem.

Don't wait until Perth is halfway through a heatwave before deciding it might finally be time to tackle the garden.

Use spring and early summer to:

• Check and repair irrigation

• Remove established weeds

• Give your garden a good water

• Protect sensitive plants

• Mulch exposed garden beds

• Check pots and raised garden beds

• Get those gardening jobs done while it's still bearable outside

Your garden will appreciate it — and so will you when you're not outside moving mulch in 40°C heat.
