Agriculture is important in Saskatchewan, but most of what is grown is grains, legumes, and seeds (for oil). The growing season is relatively short, but many farmers use hoop houses, greenhouses, and other methods of extending harvest time, so you may well find local cucumbers in November and other oddities. In any case, winter storage and root vegetables can keep you in local produce all winter long. Availability will, of course, vary based on your location within the large province as well as the specific conditions each season. The seasons listed below are based on likely availability in the southern part of the province, including Regina and Saskatoon.
