Hi, we have a steep hill that always makes me nervous cutting it with our zero turn. My wife is adamant about not trying to mow on a hill, so alternative is to use 21" self-propel Honda, which takes time and is pain in the butt. Our zero turn is 52". Thinking about replanting it with something like vinca or similar that won't have to be mowed, maybe wild flowers even, but not sure what to do about the grass there now. I think you have to kill the grass, but it's a pretty big area- don't want to use Roundup, and the size prevents covering with black plastic (also takes long time?). Can it just be rototilled and then the replacement plants can go into ground? Thanks for ideas,
