Um, but do you need soil?
I don't have a real pond, just a fishpot. (About the size of a
half-barrel). I always figured the point of the plants was to absorb
fish poop, and contribute to the balance in the system. If I'm putting
in dirt for the plants, they won't do what I want them to do.
I put my iris corms in a pot, put a brick on top to keep them from
floating, and put it in the pot. Works pretty well, mostly. They bloom
maybe one year out of three. Sometimes the roots take off and cover too
much space - then I have to whack them back. I tried putting the corm in
an old knee-high, but I don't think it did that much good.
I bought a new plant from PetCo - they couldn't tell me what it was, or
whether it would make it through the winter, but it was cheap enough to
experiment. Some of the floating leaves are developing roots. Wish it
luck - but it won't get dirt from me.
