I tried the tub idea a few years ago. There was some discussion on this
list, I think, and a link to a NARGS discussion group where they
referred to them as mini-bogs. Their discussion centered on whether the
lack of drainage holes would cause the things to go anaerobic. I used
masonry tubs, which are good, tough plastic available in a couple of
different sizes. I also used one smaller kiddie pool i picked up at the
side of the road on trash day. I did not have the guts to leave them
completely without drainage holes, and I was wrong. Ken is right, the
water will leak out. (I filled mine with a mix of peat and coarse
sand). I was trying to provide habitat for prismatica and sino
Siberians, they did no better than others planted on the surrounding
clay soil.
