I’ve put down sprigs of beach grass in the Fall, but not sod. Is your sod coming from a local mainland farm?
I assume the sod would come from an Eastern NC sod farm. I'll be sure to ask. We had a new bulkhead installed during the summer. Now our backyard is 75% sand i.e. no grass. The other 25% is grass & weeds that was undisturbed during construction. I tried planting Bermuda grass from seed with zero germination. About a month ago I seeded with a tall fescue and it germinated somewhat. I think growing grass from seed is a losing battle with the 2 dogs racing around the yard.
NCState dad I'm surprised you don't know about this site TurfFiles | NC State Extension Lot of good information here on what is best for NC. The link didn't show up. Sorry about that. Just do a search on what is above.
As far as your Bermuda seed comment, you have to make sure to purchase scarified seed to insure germination. That seed has a hard cover and doesn't absorb water very well-so no germination. Or you could pre-germinate it by pouring the seed into a bucket of water for a day or so. Zoysia seed is the same.
