Lawn Calendar

Tropical lawn calendar

Hot and humid, with a wet season and a dry season. Places like Darwin, Cairns, Townsville.

Short answer

Tropical lawns, such as Darwin's, follow the wet and the dry rather than four seasons. Warm-season grasses grow almost all year, fastest in the wet. Keep up with mowing in the wet, water less when rain is doing the job, watch for fungal disease in humid weather, and water deeply through the dry season.

In the tropics the lawn calendar follows the wet and the dry, not four seasons. Grass grows almost all year. The main jobs are keeping up with mowing in the wet, watching for weeds and disease when it is hot and humid, and watering well through the dry.

Calendar timing is general guidance for the whole zone. Watch what your own lawn is doing, and follow product labels for timing. [CONFIRM: reviewer to confirm Lawn Calendar timing for this zone]

  • Hot and humid through the wet season, roughly late spring to early autumn
  • Warm, drier weather through the dry season
  • No real winter, so warm-season grasses grow all year

Warm-season grasses grow all year. The wet season brings fast growth, more mowing, and more weed and fungal disease pressure. The dry season is when irrigation matters most.
