has anyone had success using Gly to completely get rid of zoysia in the northeast? I have a couple of lawns that are very nice, but have some spots of zoysia mixed in. Is the only way to rid of this "weed" dig it out? Or should i hit it with Gly in this nice heat we have right now. Its a shame, the lawns look great, weed free, other than the damn z mixed in.
