what type of grass is this
I live in st Louis and my neighbor's zoysia invaded and now half my yard is zoysia and the rest fescue. I've killed the zoysia half of the yard with roundup but this winter I've noticed some brown patches in the fescue half of the yard. I pulled out a sample (see picture) and want to know if this is zoysia or Bermuda grass so I can determine whether to kill it or whether it is just some crabgrass or something else not as invasive. Any help is appreciated.
