Lawn Care
in Perth
Is Different.
Perth's sandy soils, water restrictions and harsh summers mean the advice written for the rest of Australia often doesn't apply here. We've been growing and caring for Perth lawns since 1975 — here's everything you need to know to do it right.
Perth's #1 lawn care mistake: treating symptoms instead of causes. Most lawn problems come down to three things — soil health, timing and the right products. This guide walks you through all three.
Why It Matters
What Makes Perth
Lawn Care Unique
Most lawn care advice is written for heavier clay soils in the eastern states. Perth is fundamentally different — and understanding why is the key to a healthy lawn here.
Perth's Spearwood and Bassendean sands are some of the most nutrient-poor, hydrophobic soils in Australia. Unlike clay soils, they leach fertiliser quickly and repel water once they dry out. Every product choice and timing decision flows from this single fact.
Perth operates under year-round Water Corporation restrictions — typically two watering days per week for residential properties. Getting the most from those two days, through wetting agent use, correct timing and retic calibration, is the single most important thing you can do.
Summers regularly above 38°C, followed by cool wet winters — Perth lawns face a seasonal swing that demands a completely different approach across the year. The autumn preparation window in particular is critical, and it's the one most homeowners miss.
Pillar One
Watering
Getting watering right is the foundation of everything else. On Perth's sandy soils, the goal isn't just to water — it's to ensure water actually reaches the root zone rather than beading off hydrophobic soil.
- Lawns need 25–30mm twice per week when temperatures exceed 34°C
- Always conduct a retic audit with catch cups before summer — coverage gaps cause dry patch
- Apply a wetting agent in spring before the soil dries — far more effective than re-wetting in January
- One deep, slow watering is more effective than multiple short cycles
- Water early morning to reduce evaporation and fungal risk
Pillar Two
Fertilising
Perth's sandy soils have almost no capacity to hold nutrients — they leach straight through. This means Perth lawns need more frequent, smaller applications rather than one heavy annual feed.
- Apply little and often — no more than 2kg per 100m² per application
- Most important feed of the year: April/May before winter
- September/October feed prepares the lawn for summer growth
- Sir Walter, TifTuf and Zoysia need less nitrogen than older couch varieties
- For new lawns, wait until roots are established before applying fertiliser
Pillar Three
Weed Control
Weeds compete with your lawn for the limited water and nutrients available in Perth's sandy soils. The most effective approach is prevention — applied before germination, not after.
- Pre-emergent herbicides are the most cost-effective weed control — timing is everything
- March/April pre-emergent window stops wintergrass, crowsfoot and oxalis before they establish
- September/October pre-emergent stops summer weeds
- Once weeds are visible, spot spray with a selective herbicide suited to your turf type
- Never use non-selective herbicides near turf — they will kill your lawn
Pillar Four
Pest & Disease Control
Perth's climate makes lawns susceptible to a predictable set of pests and diseases at specific times of year. Knowing what to look for — and when — is half the battle.
Pillar Five
Mowing
Mowing height has a bigger impact on lawn health than most homeowners realise. The right height reduces heat stress, promotes deeper roots and cuts disease risk — and it varies by variety and season.
- Never remove more than one third of the leaf in a single mow
- Higher cuts in summer protect stems from heat stress and reduce thatch
- Lower cuts at the end of winter remove dead material and stimulate spring growth
- Sharp blades prevent tearing — a blunt blade increases disease risk significantly
- Mow regularly at the right height rather than infrequently at the wrong one
Recommended Mowing Heights
| Variety | Summer | Winter |
|---|---|---|
| Sir Walter Buffalo | 25–30mm | 30–40mm |
| TifTuf Hybrid Couch | 15–25mm | 20–30mm |
| Zoysia Australis | 20–30mm | 20–30mm |
| Nullarbor Couch | 15–25mm | 20–30mm |
Plan Ahead
Lawn Care by Season
Perth's lawn care calendar is precise. The right action at the right time makes all the difference — missing a window by even a few weeks can cost you months of recovery.
