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.
The cool Tasmanian summer is perfect for premium crops: broccoli, cauliflower, and leafy greens achieve exceptional quality and flavour without bolting.
Garlic thrives in Hobart's cold winters, plant in April or May, and the cold vernalisation process produces large, well-formed bulbs by December.
