Spring in Canberra is the prime window for warm-season crops once frost risk passes, tomatoes, beans, zucchini, cucurbits all go in now. The city sits in cool temperate territory, winter lows around 1°C, summer highs around 31°C, and the spring months (September, October, November) carry a recognisable rhythm that's worth knowing before you plant.
From seed in Canberra this spring: Tomato (indoors), Peas (outdoors), Broad Beans, Spinach, Beetroot, Carrot, Onion, Tomato (cold frame/inside), Beans, Cucumber, Zucchini, Pumpkin, Sweet Corn, Radish, Tomato, Basil, Spring Onion. That's a long list, which is the upside of Canberra's cool temperate conditions in spring, direct-sowing into raised beds gives you the best germination and the strongest root systems for the season ahead.
As seedlings in Canberra this spring: Peas (cold frame), Onion seedlings, Leek, Kale, Tomato (cold frame, frost watch), Broccoli, Onion, Peas, Silverbeet, Tomato (after last frost ~mid-Oct), Capsicum, Eggplant. Buying seedlings from a local nursery shortens the calendar by 4-8 weeks compared to seed, which matters most in Canberra's shoulder windows.
Harvesting in Canberra this spring: Broad Beans, Kale, Silverbeet, Leek, Broccoli (side shoots), Carrot, Peas, Broad Beans (last), Spinach, Broccoli, Lettuce, Radish, Kale (last before heat). The harvest peak runs across the season's middle month, when warm-season crops planted in the previous shoulder are coming into full production.
Canberra's last frost is typically around late September-early October, never plant frost-sensitive crops (tomatoes, beans, zucchini) outside before mid-October. The short frost-free window in Canberra means starting tomatoes, capsicum, and basil indoors from late August is essential to get a decent harvest before April frosts. If you want the printable, see the full Canberra planting calendar.
Canberra's spring 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.
