Hello :
I have a flagstone walkway (natural Vermont slate actually, that I scavenged from a local quarries slag heap). It is 5 feet wide and 20 feet long.

Anyways, the walkway has been in place now for 3 years. We first thought that planting the irregular gaps between the individual pieces of slate with moss and "steppable" plants creeping thyme etc would look really nice. At first it did. But now it's more grass and weeds than pretty, low growing plants and it's a pain to constantly weed it, so I'm thinking of mortaring or grouting or whatever between the pieces.
Having never done this before, I don't have a clue where to start. I've heard of dry grout mix made for this purpose that you sweep into the cracks (after digging them out a little of course) and then you wet it with a spray and it hardens. But, I'm not sure if mine is the right application for that. I live in Vermont, so it's exposed to severe winters.
Any advice on products/techniques would be greatly appreciated !
Thanks - Shawn
