Gardening in Corner Brook, Newfoundland
West Coast · West-coast valley, warmer summers
Corner Brook has one of the longer frost-free seasons of the communities LocalPlot covers. Its station records an earlier average last spring frost than the Avalon or Central stations. Valley shelter and warmer summer days make crops like tomatoes, zucchini and beans more realistic than on the east coast.

Local gardening challenges
- Valley floors can act as frost pockets even when hillsides stay clear.
