You're very welcome, and absolutely right- allow the foliage to dry till it sloughs off the corm easily.
Those baby corms sometimes grow surprisingly fast just growing them as usual in a regular length growing season. It depends on the variety, some are more vigorous than others. I've had them reach blooming size in 3 years and 2 years for smaller hardy and species types.
Jeanne, what are you calling medium size? Say nickle size?
