How to make faux natural stone out of concrete
My plan is to fully sink a large plastic (52D x 52W x 39H centimetres) trog (handles removed) into a new flowerbed. Inside, down one side, will be a few small stones stacked so any little creature that falls in will be able to climb out.
To hide the rim of the 'pond', I want to make some concrete stones which hopefully I'll be able to make them look like natural stones.
The pic below looks something that I'm looking for, but less rigid and formal, I'd like round corners with soil between the stones.
I see there's such a 'thing' as fibre reinforcement you can add to a concrete mix to make it stronger and to stop it from cracking. I also note there's a dye I could add to the concrete to give it a bit of a natural stone blend.
Think also a bit of peaty matter can be added to the concrete mixture which will help age the 'stones'.
Has anyone had success with what I'm trying to achieve? Do you have recipe? Do you have any tips or anything I should be wary of?
Thanks for any help
