Watering the grass every single day for 15 minutes. DONT’ DO IT!
This turns the lawn into a shallow-rooted water junkie that demands a water fix every day just to soldier on.
Instead of watering shallowly every day for 15 minutes, water deeply once a week for an hour or so (or how ever long it takes to apply an inch of water).
Your lawn will be healthier and more drought-tolerant. It will also have fewer loathsome weeds like dollarweed and nutgrass (nutsedge) that thrive in overwatered lawns.
