Canterbury is cool temperate with hot, dry summers and cold winters bringing regular frosts, plus the drying nor'west wind. Frost defines the calendar: tender crops wait until the risk passes (around Labour Weekend) and the season is shorter than the warm north. Brassicas, roots, and cool-season greens do well; warm crops benefit from cloches and shelter from the nor'wester.
Canterbury's cool temperate climate suits brassicas, root crops, peas and leafy greens through long cool seasons. Warm crops like tomatoes succeed in the frost-free window with shelter. Hard frosts and the drying nor'west wind define the calendar.
When can I plant tomatoes in Canterbury?
Wait until the frost risk passes, around Labour Weekend (Show Weekend in mid-November is the traditional safe date). Use cloches to start earlier, and shelter plants from the nor'wester.
How do I handle Canterbury frosts and nor'west wind?
Hold tender crops until mid-November, use frost cloth and cloches at the season's edges, and provide shelter from the drying nor'west wind. Focus on hardy crops in the cooler months and warm crops in the short summer.
