I just installed an irrigation system before seeding my brand new lawn. From what I have read minimal watering of a lawn is best. What schedule should I apply to start a new lawn? Second, once my lawn is established how should I program the system to apply an effective amount of water to my lawn?
To start, water very lightly twice a day. When you see the very first bits of grass, switch to once a day. When the grass is an inch tall, once every two days. When the grass is two inches tall, once every three days. When the grass is four inches tall, once every four days ... mow at about four or five inches and then give your grass water only when it needs it.
