Well I found this:
http://www.zoysias.com/
They sell the zoysia plugs. I believe they were sold as 36 plugs @ 3x3 (the site didn't list the measurements but I'm guessing the 3x3 is in inches?) for around $12. Is this a good price for this stuff? Would 36 3x3 plugs be enough to eventually cover roughly 200 square feet when its filled out?
Also, they have several different Zoysia types: Meyer, El Toro, Emerald and Empire. Would it make a difference which one I bought? Will you be able to tell the difference if I don't match up the exact breed?
Also, the site suggests plugs rather than seed for covering an area that already has turf. Since I'm going to be attempting to grow grass in dirt is it ok if I just seed it with the Zoysia seeds rather than the Perennial Rye followed by the Zoysia plugs?
