When to Find Mushrooms Mushrooming isn't limited to April and May however. Mushrooms can be found from February to June. Even if you knew precisely what temperature and soil moisture content causes morels to sprout, the information would be next to useless. These factors change from day to day and from hour to hour in the springtime, not to mention variations from every ridge, hillside, valley and pasture in the state. The morel patch you found dry as a bone yesterday could get a freak thundershower Sunday and be crawling with morels by Wednesday afternoon.
Persistence is the hallmark of a successful mushroomer.
The more days you spend in the field, the better the chances that you'll be there when the 'rooms are. Still, there are some factors worth considering in deciding when to hunt for morels. The day immediately following a warm rain is good, all other things being equal. A nice thunderstorm at your house is your cue to check the south 40. Following a statewide deluge, you can extend the scope of your quest to distant sites.
