I’m considering installing a fairly small pond in my back yard. I’m likely to get a preformed pond liner (maybe 3′x5′ or so, it depends on what I can find for cheap).
But I’d like part (1/3 or less) of the pond to be a bog garden. Partly to give me more plant options, partly to act as kind of a biological filter.
I’d prefer to have the dirt/dirt substitute fill the entire area, rather than just have things in pots (that gives me more options, I think). But I’m not sure if it’s practical, or if it is, how to go about it.
My thought is to get some kind of water-permeable sheeting or fabric, glue and/or silicone seal it (with aquarium-safe silicone) to the side of the pond across the area I want to portion off, then fill the portioned-off area with either dirt (quite possibly some of the dirt I dug out to put the pond in), gravel/marbles/rocks/etc, or something like perlite or vermiculite. Or I could try that polymer gel or something. (if it makes a difference, I live in Arizona, and the dirt around here is generally mineral-rich, very alkaline, and possibly a bit salty)
So, my questions are:
Is there something entirely unworkable about the whole idea?
What should I use for the barrier between the pond and the bog?
How should I attach the barrier to the pond liner?
What should I use as dirt or a dirt substitute?
