Adelaide Lawn Care Schedule
In Adelaide (Temperate, SA), lawn care follows the timing set by the Southern Hemisphere calendar and the local climate. The summary below combines zone-level defaults with any city-specific timing adjustments — use it alongside the seasonal guides linked above for month-by-month tasks.
Spring (September–November)
Apply fertiliser from mid-September as soils warm above 15°C. Avoid fast-release urea on sandy Adelaide soils — slow-release NPK is the right choice. Pre-emergent for Summergrass in late September. Apply chelated iron (Fe-EDTA at 15 g/m²) to Buffalo and Couch showing interveinal yellowing — chlorosis is almost universal on Adelaide's alkaline soils and responds within 7–10 days.
Summer (December–February)
Multiple 45°C+ days are routine. Raise Buffalo to 50 mm, water deeply twice weekly before 8 am. Never fertilise during heatwaves above 35°C. Check SA Water restriction status.
Autumn (March–May)
Adelaide's second-best lawn season. Fertilise and aerate in March. Apply wetting agent by mid-April — metropolitan Adelaide sandy soils are strongly hydrophobic after summer. Most Adelaide garden soils test at pH 7.5–8.5 due to the underlying calcareous (limestone-derived) parent material, and this high alkalinity locks out iron and manganese — producing the interveinal yellowing that every long-time Adelaide lawn owner recognises in Buffalo and Couch. The fix is not lime (soils are already alkaline, and adding lime will make the chlorosis worse) but a chelated iron product — Fe-EDTA or Fe-DTPA at 15 g/m² in spring and again in autumn. The Hills Face Zone suburbs (Belair, Stirling, Aldgate) sit on different parent material and test more acidic at pH 6.0–6.5, behaving closer to Sydney soils than to the Adelaide plains.
Winter (June–August)
Mild and wet. Buffalo holds colour through most winters, Couch semi-dormant. Apply Bindii pre-emergent in late May or early June.

No active emergency restrictions apply in 2026, but year-round water-wise guidelines recommend watering before 9am or after 4pm and avoiding midday irrigation.

How often should I water my lawn in Adelaide, SA?
In Adelaide's Temperate climate, water deeply two to three times per week during summer, applying around 25 mm per session. In cooler months, once a week is usually sufficient. Always check local water restriction schedules and water early in the morning before 9 am to minimise evaporation.

Check soil moisture first by pushing a screwdriver into the soil — if it resists, the ground is too dry. Aerating in spring and maintaining the correct mowing height of 30-50 mm helps prevent most browning issues.
When is the best time to lay turf in Adelaide, SA?
The best time to lay turf in Adelaide, SA is from mid-spring through early summer (October to December) when soil temperatures are consistently above 18 °C. Autumn (March to May) is also suitable, especially for warm-season varieties that benefit from cooler establishment conditions. Avoid laying turf during the hottest weeks of summer or in winter when root growth is minimal.
