Now don't laugh, I am not well up on weeds or weeding so here is my question.

I was given some Weedol spray yesterday to use on the few weeds that are left on the soil in our front garden.

I am not going to be growing anything on there, just puttings some paving stones and pots there for now, we may need to use the area to park on so I can always move this lot if needed.

Anyway, I sprayed the weeds that I couldn't uproot by hand and they started to go dark and wilt within a few hours.

The question is, do I lift these by hand (wearing gloves of course) after a few days or do they just die away into the ground?
