We have a sprinkler system too. Once you have one you'll never go without one. Place we're going to has one, but it needs to be upgraded.30 bags of anything isn't easy, I'd be feeling that this morning. I need to mulch here too, mostly new trees and I'm supposed to get a notification of when to put the irrigation back on them from the nursery that I bought them from. Not looking forward to that but auto watering is the way to go.
