Mushrooms in the garden, especially if they are toadstools, have never been good for anyone. This is not a sign of soil damage, but rather a signal that it is time to take action.
In general, if you do not eat these mushrooms, there is no danger. It is more important to draw conclusions.
Let's figure out what to do if mushrooms start growing.
This is a sign that the pH balance of the soil is far from neutral. If everything was fine until recently, then after the mushrooms appear, you need to think about the possibility that the cause could be mistakes in farming, stagnant moisture, and improper fertilization.
It is also worth thinking about the health of the soil. It is quite possible that somewhere shallow there is rotting or decomposing materials, which is what the mushrooms like so much.
1. Sometimes it is enough to add compounds that reduce soil acidity. Before adding lime, dolomite or chalk, you need to measure the acidity with a special device. This is necessary in order to correctly calculate the dosage.
2. Moreover, it may turn out that the problem is not acidity at all. Then the resources and efforts will be wasted. It is possible that you do not need to deacidify the soil, but to install drainage to improve air exchange in the soil.
To do this, add dry and light soil, plant nearby plants that actively consume moisture (bird cherry, birch, willow, alder, etc.), or use other techniques.
3. If the cause is not high humidity, it may be necessary to add chemical additives. In particularly advanced cases, biopreparations (Gamair, Baktofit, Fitosporin and their analogues) can help.
In autumn, you can add a 3% solution of Bordeaux mixture, and in spring, use "Oxyhom", "HOM" or their analogues.
However, it is easier to prevent the appearance of fungi than to fight them later. To do this, it is enough to follow all the rules of agricultural technology.
