Commercial Value
Chestnut mushrooms are a rare variety in the Canadian market, commanding 2–18 per pound with minimal competition from other growers. Chefs prize the nutty, earthy flavor and firm texture for sautés and roasted dishes. Because so few farms produce chestnut mushrooms domestically, you can establish yourself as the go-to supplier in your region. The novelty factor alone drives strong farmers’ market sales.

Growing Tips
Chestnut mushrooms prefer cooler fruiting temperatures in the 12–18°C range, making them well-suited to Canadian growing conditions for much of the year. Use supplemented hardwood sawdust with a standard wheat bran supplement rate. Maintain consistent humidity during pinning — chestnuts are less forgiving of humidity swings than oysters. Harvest when caps are fully expanded but before spore drop for the cleanest product and best shelf life.
