@purpleinopp,
the more I think about it, the more I think you have the best idea for over-wintering coleus....just keep cuttings in water.
Much easier to maintain, and cuts down on the gnats that seem to live in the potting soil.
So am going to take down the tower in the living room, make new cuttings from the rooted plants,
and put more bulbs (if any are left over at Home Depot) into the tower outside.
BUT will create a tower of coleus when it warms up again.
