The Lava Creek tuff. Would it damage my yard so that I wouldn’t have to mow for a while?
Why bother with grass? Do you have grazing animals? Grow food! Then you can tell the kids to stay off your garden or you’ll starve.

Yes. A good welded ash flow tuff ought to prevent any grass from growing through it for a few thousand years.
