Diseased grass from waterlogging

If it is possible for the lawn to turn yellow due to lack of irrigation, it is also possible for the opposite to happen. People without much gardening experience tend to think that the more water a plant gets, the better for it, but those of us who have been around for a while know that too much water tends to be more dangerous than too little.

When the ground becomes puddled or flooded, the roots lose the ability to breathe, and tend to rot quickly. Without a root system to feed it, the aerial part of the plant is left without a food source and soon dies. In addition, excess moisture tends to encourage the appearance of all kinds of mushroomsespecially in mild or hot temperatures, which will soon attack the grass and leave yellow zones.

Another substance very rich in nitrogen is urine. If one or several dogs urinate frequently on a certain area of ​​the lawn, they will end up with the characteristic yellow spots bordered by green, in which the outer area is rich enough in nitrogen to make fertilizer for the lawn, but in the center the concentration is excessive and has burned the grass.
