How to read the index

Mushrooms usually appear 1–2 weeks after a proper soaking, so rain from 6–16 days ago matters most, not yesterday’s.

Moist soil and about 9–19 °C push the index up. Frost and drought cut it, and the season sets the ceiling. In the Southern Hemisphere the season is shifted by six months.
