Frequently asked
- When is mushroom season in California?
- Wild mushroom season in California peaks November through February, following the first significant rains. Chanterelles appear in coastal forests from Marin to Humboldt after fall rains; morels come in spring, particularly after Sierra Nevada fires. Cultivated mushrooms (oyster, shiitake, lion's mane) are grown year-round in the Bay Area and Central Coast. Mushroom festivals and foraging events cluster in late fall and early winter when wild species are most abundant. Harvest events and U-pick windows follow the same window — check each listing for exact 2026 dates.
