Because every year is different

  • The season opens with rain: after a heavy rain, with the soil still warm, it takes one or two weeks.
  • In mountain It begins earlier and ends earlier than on the plain, and the same is true for the northern slopes.
  • A'dry summer It pushes it forward, sometimes by weeks. A mild autumn lengthens it.

The calendar says the months. Which day, in your forest, this year, the rain that fell there tells you: MushScout follows it day by day and tells you when it's time.
