Keeping Your Lawn Cool, Calm, and Collected Despite the Perth Scorcher: How to Maintain Your Lawn in Extreme Heat

Living in Perth, we know all too well the searing heat that summer brings. While we might be seeking icy treats and shady havens, our beloved lawns face a different kind of struggle. But fear not, fellow West Aussies! With a few smart adjustments, you can keep your lawn thriving even as the mercury rises. Joondalup Turf Farm, your friendly neighbourhood turf experts, are here to share some essential tips on how to maintain your lawn in extreme heat.

What Temperature is Too Hot to Water Grass?

Watering is crucial, but timing is key. The midday sun acts like a thirsty dragon, guzzling up any moisture before it reaches the roots. So, ditch the midday sprinkler session. Instead, water your lawn early in the morning, ideally before 10 am. This allows the water to soak deep into the soil before the sun’s harsh rays have a chance to evaporate it.

But how much water is enough? Here’s the golden rule: water deeply and infrequently. Aim for one inch of water per week, considering rainfall in your calculations. A deep soak encourages roots to grow deeper, making your lawn more resilient to future heatwaves.

What Temperature is Too Hot to Mow the Lawn?

While water is essential, there is such a thing as too much of a good thing. Watering during the hottest part of the day can stress your lawn further. So, when does the hosepipe get a well-deserved rest? As a general rule, avoid watering when the temperature exceeds 35°C. Trust us, your lawn will thank you for it.

Mowing mishaps: Avoiding the scalped look

Just like us, our lawns need a haircut to stay healthy. But during the summer heat, mowing can be more harm than good. Hold off on the mower when temperatures soar above 32°C. The scalped look isn’t just aesthetically unpleasant; it exposes the delicate grass blades to the harsh sun, increasing stress and water loss.

How to Keep the Grass Green in Summer?

Summer sun can leave even the most vibrant lawn looking parched and brown. But fear not! Here are some tips to keep your green oasis thriving:

• Raise the mowing height: Taller grass shades the soil, reducing moisture loss and keeping it cooler. Aim for 5-7 cm during the summer months.
• Embrace the mulch: A thin layer of organic mulch around your plants and trees helps retain moisture in the soil and keeps the roots cool. Bonus points for looking aesthetically pleasing!
• Go easy on the fertiliser: Over-fertilising during summer can stress your lawn and encourage weed growth. Opt for slow-release fertilisers specifically formulated for hot weather.
• Aerate for better breathing: Aerating your lawn allows air, water, and nutrients to reach the roots more effectively, promoting healthy growth and drought tolerance.

How Often to Cut Grass in Summer?

Remember, less is more when it comes to mowing during summer. Aim to mow every 10-14 days, depending on the grass type and growth rate. And don’t forget the 1/3 rule: never remove more than one-third of the grass blade’s height at a time.

By following these simple tips from Joondalup Turf Farm, you can ensure your lawn stays lush, green, and healthy even when the Perth heat turns up the dial. Remember, a healthy lawn is not only aesthetically pleasing but also helps regulate temperature, reduce dust, and create a cool, inviting outdoor space for you and your loved ones to enjoy. So, grab your shade hat, embrace the summer spirit, and watch your lawn thrive with Joondalup Turf Farm by your side!
