August is the end of winter. In temperate climates soil is at its coldest, so hold off on tomatoes, chillies, pumpkins and sweet corn, which want about 18°C. Sow spinach, peas, kale, broccoli and other cool-tolerant crops now. In the frost-free subtropics, spring planting begins.

Australian note: this page follows southern-hemisphere seasons, so August is in winter. 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.

Warm days can trick you into sowing too soon. Heat-loving seeds need warm soil, so unless you have a polytunnel or heated tray, wait a few weeks. Days are noticeably longer and the change of season is close.

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 August

These 8 crops are given for August 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. Most are crops these guides list for many months of the year, so the shorter list does not mean nothing else can be sown.

Crop Perth (WA Waste Authority) Adelaide (Green Adelaide) Melbourne (City of Darebin)
Beetroot Jul-Apr Listed for August Jul-Mar
Cabbage All year Plant any time All year
Lettuce All year Plant any time All year
Potato May-Nov Listed for August Aug-Nov
Radish All year Plant any time All year
Silverbeet All year Listed for August Aug-Mar
Spring onions Mar-Dec Plant any time All year
Tomato Aug-Feb Listed for August Aug-Dec

Temperate and cool gardens in August

  • Sow spinach, peas, turnips, kale, broccoli, cabbage, lettuce, Asian greens, mustard, silverbeet, carrots, beetroot and radishes.
  • In frost-free coastal areas, consider starting potatoes.
  • This is the last call for bare-root trees and shrubs. Tidy broken roots first, and soak for half an hour before planting.

Subtropical gardens in August

  • In the frost-free subtropics, start tomatoes, sweet corn, zucchini, climbing beans, cucumber, carrots, lettuce, basil, potatoes and beetroot.
  • Wait until it is very warm for capsicums, eggplants, pumpkins and watermelons.

Tropical gardens in August

  • Plant cucumbers, zucchini, squash, sweet corn, basil and okra, with perennials such as sweet potato, taro, lemongrass and passionfruit.

Arid and inland gardens in August

  • A tricky month: warm sunny days, with nights that can fall below zero.
  • Plant fast growers: radishes, turnips, Asian greens, mustard, lettuce, fennel and rocket.
  • Plant seed potatoes if you can protect shoots from late frost.
  • Early August is the first tomato sowing in ABC Gardening Australia's two-crop pattern for arid areas.

Garden jobs for August

  • Finish pruning deciduous trees and shrubs.
  • Feed fruit trees with compost and manure late in the month.
  • Where frost is a risk, start summer seeds in trays under cover.

Questions about August

Can I plant tomatoes in August in Melbourne?

Not outdoors. Soil is too cold in temperate climates. Sow in a protected, warm spot or wait.

What soil temperature do tomatoes need?

ABC Organic Gardener gives about 18°C to germinate. ABC Gardening Australia says not to plant out below 16°C.

Common questions

What should I plant in August in Adelaide and Perth?

Green Adelaide (South Australian Government) and the Waste Authority of Western Australia both list beetroot, cabbage, dwarf beans, lettuce, potatoes, radish, silverbeet, spring onions and tomato for August. 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 August?

Yes, in places. Green Adelaide lists capsicum, chilli, eggplant, leek and pak choi, which the Waste Authority guide does not give for August; the Waste Authority guide lists broad beans, broccoli, carrot, celery and climbing beans, 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 August. 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.
