I have a project in mind for the spring and I wonder about how to set it up. We have a rather small yard with a good deal of shade, but we have a sunny patio area where I would like to situate a container bog. I intend to use a cedar planter box with a pond liner or maybe a plastic stock tank. Can I get good results with something like this as a semi-permanent bog planting? It gets very cold here (Zone 5) in the winter, so the whole thing will freeze solid through the winter months. I hope that the sand an peat substrate will lessen the amount of ice expansion and stess on the container. Does this sound right?
I have looked around a little already and most of the container bogs that I have seen have been set up as seasonal features. Most of the more permanent bog gardens have used a larger depression in the ground with pond liner. I hope I can make this work in a container.
Thanks for considering this.
