Weeds Ortho nutsedge killer Legacy post 2016-05-11 No Comments Rynewt – posted 13 August 2012 12:49I sprayed my zoysia yard with ortho nutsedge killer and now my grass is brown where I sprayed. Does anyone have experience with this? I live in SC and really hope my yard is not dying!Share this:Click to share on Twitter (Opens in new window)Click to share on Facebook (Opens in new window) ← best pre emergence herbicide crabgrass Maintenance Schedule →Leave a Reply Cancel replyYou must be logged in to post a comment.
