Any time when sod is being cut is good time to lay sod. Sod is not normally cut in January, February or March because the ground is too frozen and there is often snow on the ground. The spring is a good time to lay sod because the spring rains and cool weather will mean you will have to water the sod less. Sod can also be laid in the heat of summer; just be prepared to keep it moist until it is firmly rooted. Fall is a good time to lay sod because of the cool weather. Your new sod will require less water in the fall. November and December are also great months to lay sod. You won’t need to water it very much. The sod will remain dormant and then begin to take root and green up in the spring.
