How to Maintain a Healthy Lawn in Perth’s Hot Summers

Perth summers are hot, dry and unforgiving—especially for lawns. With a few simple habits, you can keep your grass greener for longer without wasting water.

Watering Guidelines for Hot Months

Water early morning (5–7am) to reduce evaporation.
Deep soak 2–3 times per week rather than daily sprinkles.
Use a wetting agent every 4–6 weeks to help sandy soils absorb water.

Best Fertilisers for Perth Lawns

Choose slow-release fertiliser suitable for warm-season grasses.
Apply lightly in spring and early summer—avoid heavy feeding during peak heat.
Top dress thin areas with compost and sand mix.

Common Summer Lawn Problems & Fixes

Dry patches: Wetting agent + deep watering.
Weeds: Spot-treat and improve lawn density with overseeding.
Thatch: Light scarify in spring; avoid scalping.

Common mistakes: Overwatering, mowing too short (“scalping”), and fertilising heavily during heatwaves.

FAQs

What’s the best time to water?

Early morning is best (around sunrise). Avoid evenings to reduce fungal risk.

Should I mow less in summer?

Yes—mow higher and less frequently. Taller blades shade the soil and reduce stress.

Can GreenFix revive dead patches?

Often, yes. We combine wetting agents, topdressing and correct mowing heights. See our services.
