Probably happened a couple of weeks ago -- I noticed an area last

Roundup. At this time of year it could take two weeks or more to show
effect; IMHO, once you've noticed the symptom, it's curtains --
particularly for grass. Oddly enough, it seems that buttercups can
recover after a period of looking very jaundiced.

week which wasn't very green and watered it. By this week, it's
very clear from the pattern of the dead area exactly what's happened,
a dead spray shaped area with a sharp cutoff caused by the gate post.
Also, it's dying at the same rate as the weeds on the pavement.

In my area (Derry, N. Ireland) the council uses young hooligan
lookalikes on quads for weed spraying; IMHO a danger to more than weeds
and lawns.
