Leavenworth Mushroom Calendar

Leavenworth sits in the North Cascades and a moderately damp climate — about 25.7 inches of rain a year, most of it falling in the cool months from fall into spring. The ground warms and reaches early fruiting potential around April, by which point the average last frost (May 10) has usually passed. Summer dries out — July through September typically see under an inch of rain — and fruiting goes quiet until the rains return in October, kicking off the year's main flush. Winter then shuts the season down hard and early.
