Winter Watering of Dormant Zoysia in Atlanta

Direct Answer

Watering dormant zoysia in February (10 PM–12 AM) will not freeze-kill the grass, but it provides zero benefit. Dormant turf doesn't use water; irrigation only wastes water and risks fungal issues.

Correct Timing

Wait until the lawn naturally greens up in spring (typically March–April in Atlanta) before resuming irrigation. Let dormancy run its course.
