Cause mold on the soil is a fungal infection, and to provoke its appearance may several obvious signs: excessive humidity indoors, temperature is low or clogged drainage holes on the bottom of the flower pot. Because of this accumulated excess moisture, it causes the development of mold on the surface of the earth. But often the owner is responsible for its occurrence, and too often, watering plants or picking the wrong substrate for planting.
This problem appears most often with the arrival of rainy and cloudy days in autumn. In this period, the plants absorb less moisture, and the remaining water in the soil practically does not evaporate due to the decrease of the temperature in the room. This creates a great environment for fungal growth. As prevention reduce the frequency of watering and the amount of spent water. Will vzryhlite the ground to a depth of two centimeters around the plant: thus, you will contribute to the rapid evaporation of moisture.
As far as we know, mold has the ability to spread not only in width but also in depth, develops in pockets. Upon detection of mold spores in the flower pot to immediately remove them together with the top layer of soil (depth of two centimeters). Add the prepared and calcined soil in the pot, add the substrate or activated charcoal: it has antibacterial properties and absorbs excess moisture remaining after irrigation.
Then dissolve in a liter of water two grams of fundazol, the prepared solution pour the entire soil. In the future, when watering use water, acidified with citric acid or fresh lemon juice to completely destroy the mold spores. If the mold has penetrated too deep, time to hit the roots of the flower, in this case his death is inevitable.
