Sod has a much wider planting window than seed, but the best time still depends on the grass.
Tall fescue sod
NC State Extension says cool season sod like tall fescue can be installed any time in the cooler parts of the growing season, as long as the ground is not frozen (NC State Extension Gardener Handbook). Fall and spring are the easiest seasons for it, because the grass is not fighting summer heat while it roots.
Bermuda and zoysia sod
Warm season sod roots best once the soil is warm. NC State notes it will not produce roots until the soil stays above 55 degrees for several weeks, and gives a window of roughly spring until about July 1 (NC State Extension Gardener Handbook). Professional installers do lay warm season sod outside that window, but the soil must not be allowed to dry out.
What about summer?
You can sod in summer, but it takes more water. Clemson Extension warns that summertime sodding can mean extra water use because of the effort to keep sod from drying out in the heat (Clemson HGIC, Lawn Establishment).
The short version
- Tall fescue: fall or spring is ideal, any time the ground is not frozen can work.
- Bermuda and zoysia: late spring into early summer.
- Whatever the grass, the yard has to be watered well for the first couple of weeks.
