Over watered lawns frequently lead to excess blade growth, summer fungal diseases and more frequent mowing. Excessive watering of lawns also wastes water and increases the risk of fertilizer and pesticide run-off from the lawn to paved surfaces. This could negatively impact local water quality.

Lawns that receive little to no water from irrigation or rainfall during summer months will go dormant. Grass blade coloring will lighten. Most lawns will recover when water returns. During a severe drought, the grass may die and require over seeding in the fall. This may be acceptable to those looking to conserve water during summer months.
