What is the average lawn's water requirement per week during summer?

The average lawn's water requirement during the summer typically falls within the range of 1 ½ to 2 inches per week. This amount is generally considered necessary to keep grass healthy and thriving in warm weather, as higher temperatures and increased sunlight lead to greater evaporation and plant transpiration. Depending on factors such as the type of grass, soil conditions, and local climate variations, the specific requirement may vary slightly.

By ensuring adequate moisture—around 1 ½ to 2 inches—lawns can maintain optimal health and vigor, supporting root development and enhancing drought resistance. This range helps to avoid under-watering, which could lead to stress and browning, as well as over-watering, which can cause issues like fungal diseases and shallow root systems. Understanding these needs equips lawn caretakers to manage resources effectively while maintaining a lush and healthy landscape.
