I'm going to be doing a fair amount of "borders" type work with sprayer and
weed/grass killer.

My question is how much, in general, can you cut the stuff you get at Lowes,
Home Depot, etc (Roundup, ShootOut, Ortho, etc) with water without losing
much effectiveness? I guess it's a way of asking just how concentrated are
most of those products?

They vary. Read the labels.
