Now would be probably the best time to do it! Don't wait until it's Summer and 95 degrees outside. I would (if I were you) cut a couple of leaves off the bottom of the pseudostem, and cut about 1/3 off each of the remainder of the leaves, except the newest leaf. They should transplant fine, provided you get plenty of corm with the plants.

Thanks - I'm so glad that it will be possible to transplant now. I will have my DH dig them up this week. :-) I would like to save them, especially since they are doing so much better than the ones in our yard!
