Gly is glyphosate. Personally, I do not like using glyphosate in beds. I prefer either selective herbicides like Lontrel or the grass herbicides or Diquat. There are lots of preemergents that can be used in beds. Ronstar, Sureguard, Gallery, Dimension and the orange herbicides. Preen is good for grassy weed control in cool season areas.
They who can give up essential liberty to obtain a little temporary safety, deserve neither liberty nor safety.
