Yeah, scatter replicate is the way to go. Can run into a few polygons, but if you need grass, you need grass. Admittedly, entering all those numbers is a hassle. Part of my wishlist for Vue would be a function that allows you to place your object at one corner, click, and have that info remembered by Vue, then you would take it to another corner, click, memorized again. Then you could just go to scatter/rep, tell it how many you want, and zapppp, you've got grass, or trees or whatever. Good luck.
