Question
I have a 2 part question... How can I identify the type of zoysia I have and here in New York where it is sold by a limited number of suppliers, can I find it in sod form rather than plugs and sprigs which take forever to fill in? Thank for your advice.

Answer
Jack,

I'm not going to be much help.  I only use perennial ryegrass, and some bluegrasses for special circumstances, out here in Oregon.  No zoysia.  

Generally, if I'm trying to identify what grass I have growing, I let it grow up to seed.  This can give me the genus and species (by way of a book with pictures of mature grasses), but variety...yikes.  I think you need to know from the start (ie reading the seed bag), or have a really good handle on the characteristics of your grass, and compare that to variety descriptions.

And then unless I am under a very unusual time restriction, I always seed.  It's just so much cheaper than sod, and over time will do just as well, or better.

For what it's worth,
