The picking of wild mushrooms needs to go to broad-leaved forests or dense pine forests, where there will be a large number of wild mushrooms, usually from the end of April to the beginning of June. The temperature and humidity at this stage are more suitable for the occurrence of wild mushrooms. I won't go home empty-handed.
If you are picking in a greenhouse, you can contact the cultivator first. Generally, they will welcome it and the price will not be very cheap. It will be about 50% higher than the market price. Because picking by hand will destroy the mushroom bed, there is a saying of raising the price.
