Help with killing weeds off

[philbo1]

im sorry the picture is very large i couldn't make it smaller!

but basically wanted to know what people use to kill off weeds, i want something that is super strong and good!

as you can see on the stones on the left hand side i get a fair few weeds growing, there isn't many now as i have pulled them out but i would like to be able
to kill them off and not have to spend time de-weeding that section all the time

More decorative stone and salt.

You can put Black Plastic down for a few days and it will kill everything including Bugs.

You might try straight Vinegar.

You can use a pre-emergent herbicide that kills the seeds as they sprout. I'm not sure which ones you can get over there.

Roundup is great for killing weeds; it's super strong and really effective! You should consider getting the Ready-To-Use spray bottle, or even a concentrated formula if you want it to go even further.
