I have a primarily fescue lawn, but my neighbor has Zoysia.
I
hate the Zoysia.
[*] It looks [u]AWFUL from about October to May. It is brown, brown, brown, brown, brown. When I say brown, I mean BROWN. Not "browning," the way most grasses are in the winter. I mean BROWN. Like hay. It looks like hay.
[*] It is NOT weed-resistant. Neighbor's yard is
full of weeds, which are quite green when the lawn is brown. It looks terrible.
[*] It
takes over. It is completely taking over my fescue, I find it in my flowerbeds (I have to weed it out of my flowerbeds at least once per week), and it can break through weed barrier cloth. It spreads through runners, which go EVERYWHERE, including over the edge of the cement. It is difficult to edge it because of the way it grows.
[*] It might look nice from May to October, and does grow "straight up," which looks nicer than grass that lies down as it gets long, but it grows extremely quickly, so it has to be mowed often.
[*] Because it takes over, yet looks COMPLETELY different than fescue, bluegrass, or ryegrass, it looks weird in the fall, winter, and spring, when all the other grass is green or browning, but the Zoysia is completely brown.
