How much water does SOD need?
Initially, after installation you need enough water to soak the SOD all the way through and get to the soil underneath. Wet at least 1 inch down, this takes between 1 to 2 inches of water. After that, you need to put on about ½ inch of water every other day for about 2 weeks or until SOD has taken root. After that, 1″ of water per week is sufficient. These are just guidelines. The rates will vary during different times of year due to evaporation.
