Winter in Adelaide is the quiet productive season, cold-hardy greens, brassicas under cover, the year's garlic and broad beans putting down roots. The city sits in mediterranean/temperate territory, winter lows around 7°C, summer highs around 33°C, and the winter months (June, July, August) carry a recognisable rhythm that's worth knowing before you plant.
From seed in Adelaide this winter: Broad Beans, Peas, Spinach, Kale, Silverbeet, Carrot, Beetroot, Snow Peas, Onion (seeds), Tomato (indoors), Capsicum (indoors), Eggplant (indoors), Radish. That's a long list, which is the upside of Adelaide's mediterranean/temperate conditions in winter, direct-sowing into raised beds gives you the best germination and the strongest root systems for the season ahead.
As seedlings in Adelaide this winter: Onion seedlings, Leek, Kale, Cabbage, Silverbeet, Broccoli. Buying seedlings from a local nursery shortens the calendar by 4-8 weeks compared to seed, which matters most in Adelaide's shoulder windows.
Harvesting in Adelaide this winter: Broccoli, Cauliflower, Kale, Leek, Silverbeet, Spinach, Asian Greens, Broad Beans (early podding), Peas (early), Broad Beans. The harvest peak runs across the season's middle month, when warm-season crops planted in the previous shoulder are coming into full production.
Adelaide's extreme summer heatwaves (40°C+) can kill vegetable plants within hours, keep shadecloth on hand and water deeply the day before forecast heatwaves. The Adelaide Hills is its own microclimate, if you garden above 400m, treat your conditions more like Canberra and expect frosts from June to September. If you want the printable, see the full Adelaide planting calendar.
Adelaide's winter suits raised beds for the simple reason that raised beds warm faster than ground-level soil, giving germination a head start and pushing transplants ahead by a week or two, which compounds across a 12-week growing window. The raised bed calculator sizes the bed; the companion planting guide fills it out.
