I'm not sure this is the right forum, but I looked in the "Trading Plants" forum and all I saw was about irises. I'm planning a trade to London (I'm in California) with rhizomes of Heliconia Schiedeana. I'm not sure exactly what the best method is? Do I dig up a good size rhizome that is fully leafed out, and cut the leaf stalk down to a couple of inches? That's the way I've bought them at plant sales, so I assume that's OK? Do you just need a good hunk of the tuber, or do you need to try and dig one with another ''eye" like a canna rhizome? Do you cut all the roots off, or leave the large ones? I have to send them bare root, as they won't allow soil (live plants) through customs. I think I need to dry them, so they don't arrive a moldy mess, but how long do you dry them? I let one sit in the house for about four days, and the cut part of the leaf stalk had already turned black? It didn't look good... but we are having nice hot weather right now, so apparently I need to dry them outside? Should I dust them with sulphur? If so, how much, and when? It's the only fungicide I have.
Any input would be greatly appreciated. I don't want to send a bad trade out and have someone disappointed over the rhizomes they receive.
