Planting guide
What to plant in Brisbane, Australia in September
September is spring in Brisbane's humid subtropical climate. Frost is never much of a factor and the soil is warm, so this is prime time to plant heat-loving summer crops and get them established before the humid, wet summer brings heavy rain and higher pest and fungal pressure.

Timing notes
- Plant summer crops early in spring so they can fruit before the humid wet season, when tomatoes especially struggle with fungal disease.
- Space plants generously for airflow — humidity, not cold, is the main gardening challenge in Brisbane.
- Mulch and mound beds to cope with heavy summer downpours and keep roots from waterlogging.
