Do any lawn experts recommend a practice I read about a few days ago that during a three week period of little rain you should still water you lawn while it is dormant just enough so the the plant below , maybe called the crown, not sure , is able to bounce back when it does rain ?
What they are saying is even though cool season grasses can survive a two to three period of little to no rain , that if it goes beyond that you may face a lawn that is dead.
They stated watering 1/2 inche every two weeks . They recommend not to water too much to cause the grass to exit dormancy because that causes stress on the grass and it uses up its fuel / energy stores
