vinegar
If you are having a fungus problem, look in your kitchen cabinet or pantry for the answer. Vinegar has so many uses and killing fungus is one of them. Add about 3 or 4 tablespoons per gallon of water and use a sprayer to cover problem areas. Water your lawn in the early morning hours. If you wait till the cool of the evening, the water will not have the opportunity to go through its natural evaporation process, thus encouraging fungal growth. Another way to control fungus is to apply liquid seaweed. It is chocked full of the nutrients that lawns need. Apply it monthly for the full benefits of this cure-all. It is very inexpensive!
baking powder
Fungus can be killed with an array of different products. Baking powder mixed with water can be sprayed over an infected area and the baking powder will act as a neutralizer to eradicate the fungus. Plain corn meal is another natural ingredient that will accomplish the same result. Before using any product, natural or otherwise, it should be determined which kind of fungus is present and which product would be best used as a lawn fungus treatment.
Another important part of
lawn fungus treatment is to make sure the soil and grass has enough nitrogen present. Too much, or too little nitrogen can cause problems with allowing fungus to grow. The right fertilizers should be used in the correct amounts to make certain that a lawn receives the most beneficial amount of nitrogen and other elements.
