The growing season in Alaska and northern Canada varies depending on the location, but generally ranges from 50 to 100 days. This short season is due to the cold climate and short summers in these regions, which limits the time available for plants to grow and mature. Gardeners in these areas often use cold-hardy and fast-maturing plant varieties to make the most of the growing season.
For some crops the growing season is too short.
