Against my advice, a neighbor installed several pallets of zoysia under heavy oak shade. Receives at most two hours of sun. He claims the HomeDepot Landscape Center salesperson sold him that it would work. Solid sodded, but I don't give it much hope long-term. I do know that the shade is heavy enough that St. Augustine would have a tough time in its location---no way bermuda. I have little experience with zoysia, so will I be able to say "I told ya so"?
