September is the first month of spring, but nature does not follow the calendar. In temperate climates, wait until frost risk has passed before planting tender crops. Plant Asian greens, spinach, beetroot, carrot, peas and potatoes now. The subtropics and tropics can plant summer crops.

Australian note: this page follows southern-hemisphere seasons, so September is in spring. The lists below are grouped by five climate zones: temperate, subtropical, tropical, arid and cool. The Australian Vegetable Garden Planner uses the same five zones. For every crop across the year, see the Australian vegetable planting calendar.

The weather warms, but there are still cold days, rain and wind. Early spring is the best time to mulch garden beds, while the soil is moist and slowly warming.

Crop lists show what both Gardenate and Deep Green Permaculture list for that climate. The two share a common lineage, so we treat them as one view and use ABC Organic Gardener's monthly column as the independent check. "Start under cover" marks heat-lovers those lists include that ABC advises keeping out of cold soil.

Where three sources agree in September

These 17 crops are given for September by all three of the Perth (WA Waste Authority), Adelaide (Green Adelaide) and Melbourne (City of Darebin) guides. They are temperate-zone city sources, not a statewide rule, so treat them as a cross-check and not a promise for Sydney, Canberra, Hobart or anywhere in the tropics or arid inland.

Cabbage All year Plant any time All year

Questions about September

Is September too early to plant tomatoes in Australia?

In temperate climates, usually yes: wait until frost risk has passed. ABC Gardening Australia says warm temperate gardeners can start from September, so go by your own soil temperature.

What should I mulch in September?

Mulch beds now while the soil is moist, keeping mulch off stems.

Common questions

What should I plant in September in Adelaide and Perth?

Green Adelaide (South Australian Government) and the Waste Authority of Western Australia both list beetroot, cabbage, capsicum, celery, chilli, cucumber, dwarf beans, eggplant, lettuce, melons, potatoes, pumpkin, radish and silverbeet for September. These two guides cover Adelaide and Perth only. Check frost and soil warmth in your own garden.

Do the Adelaide and Perth guides disagree for September?

Yes, in places. Green Adelaide lists leek, pak choi and peas, which the Waste Authority guide does not give for September; the Waste Authority guide lists broccoli, carrot, climbing beans, garlic and sweet corn, which Green Adelaide leaves for other months. Where they differ, treat the crop as possible rather than certain and check local advice.

How we checked this

The table above uses three Tier 1 (government) sources for the temperate zone. We read the Perth and Adelaide guides on 4 November 2026 and checked the Melbourne guide on 3 November 2026.

  • Green Adelaide, South Australian Government (Tier 1): what to plant when, the month lists and the plant-any-time list for Adelaide.
  • Waste Authority of Western Australia (Tier 1): Edible School Garden Guide, the planting and harvest guide for Perth.
  • City of Darebin, Victoria (Tier 1): Sow what when guide for Melbourne.

Sydney, Canberra, Hobart, Darwin, Cairns and Alice Springs lists have not been checked against a Tier 1 month table. The crop lists in the climate cards above come from the sources named in the Sources list and have not been changed by this check.

Added 4 November 2026: a Common questions section for September. They use only the two state-government guides above (Green Adelaide and the Waste Authority of Western Australia), and only where both lists were read. We show where the two guides differ and who says what. We did not add an answer for Melbourne, Sydney, Brisbane, Hobart, Canberra or Darwin because no state-government month table was reached for those places.
