For lovers of "quiet hunting" autumn is the very time when it is time to go to the forest for mushrooms. Although they begin to grow already in spring, the most popular is the autumn mushroom, namely the white one.

The conditions for the growth of porcini mushrooms have their own specific nuances. Therefore, going to the forest, every mushroom picker should know what kind of weather these fruit bodies love and what temperature they prefer most.

Note that the mycelium of porcini mushrooms grows from early spring to late autumn. The growth of the porcini mushroom depends on a constant flow of air, humidity and a certain temperature. The mycelium penetrates the upper soil layer to a depth of 15 cm.If drought or excessive moisture lasts for a long time in the places where the porcini mushroom grows, as well as soil compaction or early frosts, the fruit bodies develop very poorly and the mycelium dehydrates. Therefore, for good growth of mushrooms, air humidity and warmth are needed, especially in the surface layers.

Humidity and air temperature for the growth of porcini mushrooms after rain

The growth rate of the porcini mushroom will be good only when the relative humidity is up to 60%. If drought sets in after the rainy season, the fungus stops growing, even if there is enough moisture in the soil. The fruit body of the porcini mushroom is not protected from evaporation, therefore, at low air humidity, it dries up. Mushroom pickers with extensive experience know that you need to look for a porcini mushroom under the moss or in the forest floor.

The second important factor affecting the growth of the porcini mushroom is the temperature regime, which will also affect the growth of mycelium and the growth of spores. At the same time, it must be said that spores can grow at low temperatures, for example, at + 8 ° C.

The optimum air temperature for the growth of porcini mushrooms is from +18 to + 28 ° С. Fruit bodies grow especially quickly in rainy warm weather; their growth can last for a whole month. The average weight of a mushroom during this period is up to 250 g. Already on the fourth or fifth day, the average weight of a young mushroom can reach up to 150-180 g. And after the rains, the growth of porcini mushrooms only increases: sometimes mushroom pickers find boletus up to 10-12 cm hats up to 15-18 cm in diameter.

Boletus (porcini mushrooms are also called) live up to 12-14 days. First, the leg stops its growth, after 2-3 days, and the cap. As soon as spores begin to form, the fruiting bodies of the porcini mushroom rapidly age.

Growing sites of porcini mushrooms are an important condition for good harvests. These fruiting bodies can grow in one place for several years in a row. However, this condition will depend on how you treat the mycelium itself. Therefore, beginner lovers of "quiet hunting" should learn - the legs of porcini mushrooms must be carefully cut with a knife, leaving the lower part in the ground so as not to damage the future harvest. Next year, when picking mushrooms, you will definitely find boletus in old places.

The growth time of porcini mushrooms depends on the climatic conditions and latitudes in which the forests are located.

Favorite growing places of porcini mushrooms

These forests are considered the most characteristic landscape for the growth of porcini mushrooms. Such fruiting bodies have a brown cap and stem, prefer sandy or loamy soil. In the spruce and fir forests, boletus grows on moss and lichen litters, which mushroom pickers call "a real porcini mushroom."

Deciduous forests. There are much fewer such forests on the territory of Russia than pine ones. However, porcini mushrooms can also be found in them. Birch forests or birch groves are considered a favorite growing place for porcini mushrooms. Fruit bodies in these places have a light shade of the cap and legs, as well as a more pleasant pulp taste.Prefers borders between overgrown and open areas, as well as forest edges and well-clarified glades.

Mixed forests. In these forests, you can often find clusters of porcini mushrooms. Perhaps this is influenced by the original undergrowth of mixed forest areas. In addition, birch often grows in them, which can provide a high yield of boletus mushrooms.

Growing sites of porcini mushrooms are common in forest areas around the world, except for Antarctica and Australia. As we have seen, they grow in deciduous, pine and mixed forests. These fruit bodies have conquered almost all of Europe, North and South Africa, Central America, Turkey, China, Japan, Siberia and the Far East. In the forest-steppe zones, the abundance of the growth of porcini mushrooms is noticeably reduced, however, the boletus completely disappears when moving to the steppe zone.

Knowing the favorite places of growth of the porcini mushroom and the time of its fruiting, you can safely go into the forest and look for these amazingly tasty and fragrant fruiting bodies. Having found such places, carefully cut off the legs with a knife so as not to damage the mycelium. In subsequent years, you will certainly collect more baskets here.
