I planted some Zoysia companion about 1 1/2 years ago. It has been taking off pretty good since then. This will be the 2nd full summer that I have had it. I still have about 1/4 of the lawn that is still waiting for it to make it's way up there. I recently start plugging now that the Zoysia is established in the other section of the yard. I noticed yesterday while mowing that there is a fair amount of sometype of broadleaf growing. The only thing ever planted were companion Zoysia and some perennial rye for winter color. I noticed that the broadleaf grows at a faster rate then the Zoysia. But is it a weed? Or something else? Below are some photos for comparison sake. Also, the last photo. Can you tell me if that is a Zoysia seed head or something else?
