Hi all, not sure if this is a good forum for this question.. I overwintered tubers of the mirabilis, and re-started them in about a 18 inch pot, & fairly deep, now they are huge. I'd kind of like to really let them loose, in a much larger pot ( three tubers in the pot ) would it be too late to pot them up in something larger? I'm in Alberta, about zone 3b, and things are just really popping now, we haven't had much really warm weather at all, but I'm sure it's coming. Any ideas welcome!
