Hi,
I bought a new house a little over a year ago and it has an area paved with concrete slabs which are laid loose on a sand bed with no jointing material between the slabs. There was extensive weed and unwanted grass growth between the slabs.
I sprayed it with roundup and cleared most of the dead foliage but didn't have time to do anything else. Some weeds and grass have grown back between the slabs most of which I have cleared with a weed rake.
I would like to put in the weed resistant sand which you just brush into the joints (the loose type, not the type that sets hard) but I believe that there are probably quite a lot of dormant weed and grass roots remaining which will probably just push through the weed resistant sand. So I am wondering what the best way to tackle this is. I was thinking either:
1. Put in the weed resistant sand and then treat anything that pushes through with round-up, pull up the dead weeds and then put in more sand where they came through if necessary.
2. Put down a residual weedkiller such as pathclear hoping this will kill the roots (even though there is no foliage) and then put the sand in after.
3. Just wait for the weeds to grow, put round-up on the new foliage, pull them out and then put the sand in.
Which would be the best choice or is there a better way?
