Grass Edging on a Pond
Good Evening All..
I'm just finishing off my wildlife pond and would like to edge it with grass turf. I don't want to get too much soil into the water, but, bingo! i've just read that rockwool can be used as a growing medium instead of soil. Does anybody have experience with this?
The point is, I would like to have the eventual grass actually touching the pond water surface, but I've made a bit of a mess with the pond liner so don't feel soil will sit too securely on top of it.
Any advice or experiences would be most welcome
