Can someone advise how much round up to use to kill a few reappearing
weeds?
Basically I use a knapsack sprayer which holds approx 2- 3 gallons. I use
round up from the container which I think is either 500 or 1000ml . I
generally throw 2 - 3 of these round up container capfuls to the knapsack.
Am I using too much / too little? The weeds concerned are mainly grasses
growing through a stone/gravel lane.

Read the information on the bottle or the packaging.
