Cool / Highland Climate Zone
Tasmania · Australian Capital Territory · Victoria
Cool winters with regular frost, occasional snow in elevated areas, and mild summers. Found in Tasmania, the ACT, and highland regions of Victoria and NSW. Cool-season grasses perform best here, though some warm-season varieties can survive.
Seasonal Highlights
Summer
The primary growth period for warm-season grasses. Water 20–25 mm per week and mow at 35–45 mm. This is the best time to fertilise kikuyu or buffalo varieties. Enjoy the lush growth while it lasts.
Autumn
Overseed warm-season lawns with perennial ryegrass in April for winter colour if desired. Apply autumn fertiliser by mid-March. Reduce mowing height slightly to discourage snow mould in frost-prone areas.
Winter
Heavy frosts can turn warm-season lawns completely brown. Cool-season fescue and ryegrass remain green. Avoid mowing frozen turf. Keep fallen leaves cleared to prevent smothering and disease.
Spring
Patience is key — warm-season grasses may not green up until late October or November. Apply a spring fertiliser once active growth resumes. Dethatch and aerate in November if needed.
