Although there has been no shortage of rain recently, the forests have not filled with mushrooms. Of course, small quantities can be found, such as chanterelles, but considering that it is September, there should be many more mushrooms. How is this possible when it is widely known that mushrooms grow after rain? Foresters and experts explain that not only moisture is crucial, but also patience and suitable soil conditions.
After hot weather, the mycelium in the soil is dried out and needs considerably more time to recover and begin fruiting. Although the recent rainfall has moistened the top layer of the forest floor, the water has not yet had time to reach the deeper layers where the mycelium develops.
Why are there still no mushrooms?
- The mycelium needs time: After a long drought, the mycelium enters a state of "dormancy." Even heavy rainfall needs several days, or even a week, to fully hydrate it and stimulate growth.
- Temperature: Mushrooms grow best in a humid environment, but they also need a suitable temperature. The optimal conditions are around 15–20 degrees Celsius. Cold nights may slow this process down.
- Excess water: Paradoxically, excessively rapid or heavy rainfall can harm the mycelium. Soil that is too wet becomes waterlogged, making it difficult for the mycelium to breathe and fruit.
Experts reassure us that if suitable humidity and temperature persist, a flush of mushrooms can be expected in the coming days. Mushroom pickers should nevertheless be patient and wait for the right moment, preferably a few days after the rainfall has stopped.
