Mushrooms are one of the few crops that can be grown in Canada year-round.
Canadian farmers grow more than 145 million kilograms of mushrooms every year—mostly white button, followed by brown and Portobello. Demand for specialty mushrooms, such as Shiitake, Oyster, King Oyster, and Enoki, continues to grow. Oh, and the little black specks you sometimes see on mushrooms at the store? That’s the very important compost mixture (called substrate) used to grow beds of mushrooms—just rinse or wipe it off before eating.
