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.
See http://www.shawn-and-lisa.com/PhotoAlbumOurHouse.htm for 2 pictures of
it (the pics are in the first row, 2nd and 3rd pic across).
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
