Gray mold - natural treatment

Fighting gray mold naturallyis first and foremost about using the right cultivation methods. First of all, when planting plants, keep a sufficiently large spacing so that they do not grow too densely packed. When watering, the above-ground part of the plant should not be soaked, the water should be directed directly to the ground. It is worth ventilating rooms with plants, especially foil tunnels or frames.Let's not forget about the crop rotation, changes in the crops grown in a given position are very important. Plenty of light should also be provided to the plants to grow.

Very important in is appropriate fertilization of plants. Properly fertilized plants are stronger and less susceptible to disease. However, it should be remembered that the deficiency of nutrients in the soil can be just as harmful as their excess. In particular, nitrogen over-fertilization should be avoided, as its excess promotes too vigorous growth of green plants (leaves and shoots), excessive density of crops and easy transfer of the fungus causing gray mold to the next plants.
Remember to regularly check the plants for visible
signs of gray mold When we notice them, the affected parts of the plant should be removed, preferably burn.You should also be extremely careful when picking the fruit. Damage to the peel should be avoided, the fungus can easily penetrate the fruit through such a wound. Any containers in which we keep the fruit should first be thoroughly disinfected to remove the fungus spores left over from previous use. Strictly following the preventive rules is the best way to prevent gray mold naturally.
