I've been growing my outdoor CPs in pots with extra deep water saucers. They do fine and dandy usually (dormancy has been a problem due to kentucky weather's bipolarity). The main hassle is keeping them all watered during the summer. So I was thinking of another way to grow them. At home there is an old bathtube that is of no real use to us, and I'm wondering how I could turn that into a bog. The main questions would be: "how should I clean it out? How do I go about making drainage for it? How deep should I make the soil? What would be a good way to keep it moist during weeks when there isn't rain?
Thanks for any help.
