Great tip.
I am not doing cuttings. I have begun to convert containers to perennials and dont nees as many coleus as in past. They take up my whole livingroom and obscure the view of birds on the lawn. I am even moving the feeder to a further tree to escape the seed-weeds next summer.
DD will take cuttings and watch them in her part of the house. I will do a small order frm RD next winter.
