Dates are for a typical year and the middle of the window is the safest. Sow a little at a time across a window rather than all at once. Cold snaps, heat waves, frost pockets and city warmth all shift the real dates; watch the forecast.

Frost dates in Adelaide

Frost is rare in Adelaide: fewer than half of winters have one, going by the average winter lows. Heat and the dry or wet season matter more here than frost; the calendar works around them.

The zone follows the USDA scheme: bands of the average lowest temperature of the year, 10 °F wide, split into a and b halves. Estimated from monthly climate normals; about one city in ten we checked comes out a full half-zone off. It tells you which perennials survive winter, not when to sow.
