Putting In Decking. Poison Ground?

anotheruser

Planning to put a bit of decking in over some stones.
It fairly regularly sees weeds, so thinking I should water in some poison a few days before putting it in.
Is there anything else I should do?

Thanks!

Forget the poison & put in some weed membrane instead..?

Clear the ground of all growth as much as you can. Check for roots and as advised put some membrane down.
