Our city (Minneapolis area) is on an odd-even watering schedule which means I can water either every other day or every fourth day. "They" say an inch of water per week is recommended so if I water every other day that would mean roughly a quarter inch of water each time which is not good for the grass. So that leads me to watering heavily every fourth day but during hot weather that sure seems like a long time between waterings. What do the experts recommend? Thank you for any advice, Joel B.
