Lawn care in Northern Territory
The Northern Territory has two very different lawn climates: the tropical Top End around Darwin, with a wet season and a long dry season, and the arid centre around Alice Springs, with hot summers, cold winter nights and little rain. In both, efficient watering is the key to a good lawn.
Short answer
The Northern Territory has a tropical north, where lawns grow all year and the calendar follows the wet and dry seasons, and an arid centre with hot summers, cold nights and little rain. In the Top End, switch irrigation off in the wet and water deeply in the dry. In the centre, water deeply and early in the hot months. Use Power and Water's Living Water Smart advice to avoid overwatering.
The Northern Territory’s two main lawn climates need different calendars. In the Top End, lawns grow all year and the year is shaped by the wet and the dry. In the arid centre, summers are hot, winter nights are cold, and rain is scarce all year.
In both, the biggest risk is overwatering. Power and Water’s advice for the Territory identifies overwatering gardens as one of the biggest sources of water waste, and its Living Water Smart program offers irrigation advice for the Darwin region, including the Weather Web network of local rainfall data.
Across the Territory:
- Use the right calendar. Use the tropical zone on the Lawn Calendar in the Top End and the arid and inland zone in the centre.
- Water to the weather, with a smart controller or rain triggers where you can.
- Check the NT Government’s requirements before reusing greywater.
- Watch for armyworm in the warm, humid months in the Top End.

Climate
- The Top End, including Darwin, is tropical: hot all year, with most rain from November to April and almost none from June to August.
- The centre, including Alice Springs, is arid and inland, with hot summers, cold winter nights and low rainfall.
Best grass types for Northern Territory
The lawn year in Northern Territory
The wet season in the Top End: switch irrigation off or use rain triggers, and watch for armyworm. In the centre, the hottest months: water deeply and early.
In the Top End, bring irrigation back on as the wet eases. In the centre, prevent winter grass before it germinates.
The dry season in the Top End, when lawns need watering. In the centre, lawns slow down with cold nights.
The build-up in the Top End: water deeply until the rains start. In the centre, feed once lawns are growing strongly.
Common weeds by season

Pests and diseases to watch
Armyworm are most common from about November to March in the tropics. Check at dusk with a torch if patches appear quickly.
Watering and water rules
Water rules change. Check the current rules with your water authority before you plan watering or install irrigation. We link to the official pages rather than repeating rules that may be out of date.
