Ione Mushroom Calendar
Ione sits in the Northern Rockies and a moderately damp climate — about 28.2 inches of rain a year. The ground warms and reaches early fruiting potential around April, by which point the average last frost (May 4) has usually passed. Summer dries out — August typically sees under an inch of rain — and fruiting goes quiet until the rains return in September, kicking off the year's main flush. Winter then shuts the season down hard and early.
