Remember, water according to the weather, not according to the calendar. We aim for a certain amount of accumulation per week.

WHEN to water? Morning, but not too early. Watering super early in the morning/in the dark can lead to fungal issues, especially if you have St. Augustine. If you have Bermuda or Zoysia, starting right around sunrise is a good rule of thumb. If you have St. Augustine, one hour after sunrise in the summer is good. For spring/fall/winter, if you even need to water at all, we'd recommend starting a full two hours after sunrise to reduce your fungus risk.

"High Temp" refers to high temperatures for the week. For example, if we are hitting even just one high temperature in the 80s during a given week, you should aim for 1 inch accumulation for the week. Hitting the 90s? 1.5 inches per week. 95+? 2 inches.

If nature has provided the target accumulation amount for the week via rain, you should not be watering extra, as this can lead to fungal issues.  Each watering session (except for when highs below are 80) is aimed at providing ~0.5 inch of accumulation.
