Zone 4 has a shorter growing season than most others in the USDA garden zones.
A last frost date around mid-May and a first frost date around mid-September means a frost-free season from the beginning of June through early September. These dates are general guidelines, so watch the weather forecasts before planting.
A shorter season than most and an average low temperature of -20°F means shorter season, hardy vegetables are the best choice.
