How does excess water affect the color of the grass?

Excess water can cause the grass to turn yellow due to a range of factors, including nutrient deficiencies, oxygen deprivation, and increased susceptibility to disease. When the soil is waterlogged, the roots of the grass are unable to absorb essential nutrients, such as nitrogen, iron, and magnesium, which are necessary for healthy growth and development. As a result, the grass may exhibit a yellowish or pale green color, which can be an indication of underlying health issues. Furthermore, excessive water can also lead to the growth of algae and other microorganisms, which can give the lawn a slimy or mossy appearance.

In addition to nutrient deficiencies, excess water can also cause the grass to turn yellow due to oxygen deprivation. When the soil is waterlogged, the air pockets in the soil become filled with water, preventing the roots from receiving sufficient oxygen. This can cause the grass to become stressed, leading to a range of problems, including chlorosis, which is characterized by a yellowing of the leaves. To prevent this issue, it is essential to ensure that the lawn is receiving adequate oxygen and nutrients, which can be achieved by adjusting the watering schedule, aerating the soil, and applying fertilizer as needed.
