I've rescued a Rhodie which overwintered badly in a poorly drained area of the garden. It had collapsed and showed very little healthy root. I have teased out the root, put it in a large pot, and have been feeding it little bits of rooting solution and keeping it slightly moist for over a month. It is coming back. Before it gets too enthusiastic, I'd like to put it in a big wooden planter, something wider at the top than at the bottom. I think I've seen such a planter, about 3 feet square at the top, maybe a foot and a half square at the bottom, not more than 2-3 feet high, but I have not been able to find a supplier. Any ideas?
