Lawn watering schedule as temps drop? (Zoysia palisades - Gulf Coast)

Generally, Zoysia requires 1-1.5 inches per week.

I would be watering that new section at least three times a week, about an inch per, in the am.

The older, established section does not have to be watered as much. Just watch it and it will tell you when it is thirsty...the blades will begin to curl on itself.

As the temps drop and the amount to daylight shortens, your turf will begin to do dormant. My concern would be for that new section. Concentrate on it. Look into fertilizer with a higher K rate (something like 7-0-20) to help the young turf get through the stress of winter.
