How to Prepare Your Lawn for Summer Heat

Keep Your Brisbane Lawn Green & Healthy All Summer Long

As the Brisbane summer approaches with its scorching sun and dry spells, your lawn needs extra care to stay green, thick, and healthy. Whether you’re a homeowner or managing a commercial property, preparing your lawn for the heat can save you time, money, and water in the long run.

Here are 7 practical steps to get your lawn ready for the Aussie summer:

1. Mow at the Right Height

Avoid cutting your grass too short before summer. Taller blades provide shade to the soil, reduce evaporation, and protect roots from heat.

  • Ideal mowing height:

    • Couch & Buffalo grass: 30–50mm

    • Kikuyu: 40–60mm

  • Mow regularly but never cut more than one-third of the grass blade at a time.

2. Water Deeply, Not Frequently

A deep soak encourages roots to grow deeper into the soil, making the lawn more drought-resistant.

  • Best time to water: Early morning (before 8am)

  • How often: 2–3 times per week (depending on rainfall and council restrictions)

  • Avoid watering at night—this can encourage fungal diseases.

3. Aerate the Soil

Compact soil blocks nutrients and water from reaching the roots. Aeration helps loosen the ground and allows your lawn to breathe.

  • Use a garden fork or aeration machine

  • Ideal time to aerate: late spring or early summer

4. Apply a Summer-Ready Fertiliser

Choose a slow-release fertiliser with high potassium to strengthen the grass for summer stress.

  • Apply in early summer

  • Water well after fertilising

  • Avoid high-nitrogen fertilisers during extreme heat

5. Control Weeds Early

Weeds compete with your grass for water and nutrients. Take control before the heat peaks.

  • Use a selective herbicide or manually remove them

  • Spot-spraying is better than blanket spraying in hot conditions

6. Clear Debris & Mulch Smartly

Remove leaves, sticks, and other debris that can block sunlight and create pests.
You can mulch your clippings if the grass isn’t too long—this helps retain moisture and add organic matter.

7. Hire a Lawn Care Professional

If you don’t have the time or tools to maintain your lawn, a professional can help with:

  • Lawn mowing & edging

  • Fertilising & weed control

  • Aeration & seasonal maintenance
