Q.Zoysia grass
I’ve heard the best is El Toro but I understand it is tough getting the roots to take. Any advice?
I would recommend you contact your local County Extension Office.
They are a valuable source of information, and will be able to help you determine the best Zoysia to use in your region.
Here are several links with more information and a link to help you locate your closest office.
