ivy killing grass
I am looking for a ground cover that will go to the grass and stop
Bannock County Idaho
Sorry, I don't think there is such a thing. Fortunately (or unfortunately), nature does not think in terms of discrete lines like we often want to see in a landscape. To create such a line will require using some kind of barrier (i.e. concrete mowing strip) to keep the grass out of the ivy and trimming maintenance to keep the ivy out of the grass.
