I am constructing a 16 sq m butyl-lined wildlife pond. I have built
shelves
200mm (8") deep and 500 (18")mm wide. Because the pond is quite large and
will need many marginal plants I intend to plant direct into soil on the
shelves. I will try to shape the soil under the butyl to provide a small
dam
to retain the soil.

Is this reasonable? Any recommendations?
=========================
I tried that in our original pond. Never again. When it came time to thin
out the plants they were one solid mass. The soil had become waterborne and
with the algae the filter pad clogged constantly. We pulled the whole mass
out in sections and now all the plants are in pots. It controls their
growth and they're easy to prune, repot and/or move around.

Frugal ponding since 1995.
