Cool Temperate
Autumn in Hobart is the underrated second planting window, brassicas, leafy greens, garlic, broad beans all go in as the heat eases. The city sits in cool temperate territory, winter lows around 4°C, summer highs around 24°C, and the autumn months (March, April, May) carry a recognisable rhythm that's worth knowing before you plant.
From seed in Hobart this autumn: Broccoli, Kale, Spinach, Silverbeet, Asian Greens, Radish, Mache, Garlic, Broad Beans, Radish (quick), Spinach (cold-hardy). That's a long list, which is the upside of Hobart's cool temperate conditions in autumn, direct-sowing into raised beds gives you the best germination and the strongest root systems for the season ahead.
As seedlings in Hobart this autumn: Broccoli seedlings, Kale, Silverbeet, Asian Greens, Lettuce, Garlic, Broccoli, Silverbeet (frost-tolerant spot), Leek, Broad Beans. Buying seedlings from a local nursery shortens the calendar by 4-8 weeks compared to seed, which matters most in Hobart's shoulder windows.
Harvesting in Hobart this autumn: Tomato, Zucchini, Cucumber, Beans, Lettuce, Silverbeet, Radish, Tomato (harvest before frost, urgent!), Zucchini (last), Beans (last), Broccoli, Carrot, Beetroot, Kale, Leek (early). The harvest peak runs across the season's middle month, when warm-season crops planted in the previous shoulder are coming into full production.
Hobart's short frost-free window means starting tomatoes and capsicum indoors from August is not optional, it's essential to get a productive harvest before April frosts. Cold frames and cloches extend Hobart's season dramatically, invest in a simple cold frame to push plantings 4-6 weeks earlier in spring and extend harvests in autumn. If you want the printable, see the full Hobart planting calendar.
Hobart's autumn suits raised beds for the simple reason that raised beds drain faster and let you control the bed mix, both of which matter when the season's weather extremes try to either drown or bake your crops. The raised bed calculator sizes the bed; the companion planting guide fills it out.
