I have never used weed killers. A probably irrational horror of chemicals.
Anyway I have a small area of cobbles, stone sets set in sand (no cement
between or below) and I have been persuaded that a weedkiller may be the
best way to clear the large amount of grass and weeds coming through the
gaps.

I think I have heard that the right chemical will leave some attractive
moss growing but kill the leaved plants. What would that be? The cobbles
are constantly crossed by pets and humans so there is considerable danger
of getting it indoors on the carpets and cats eating it. But I could make
sure the pets didn't go on it for a while.

roundup should do it or any other total weedkiller
