Transplanting shade perennials
I have a shade garden, composed of bleeding hearts, hostas, astilbe, snake root, huchera, etc., that will be impacted by an addition to our home. We expect construction to start in the late winter of 2014, maybe early March. I would like to move or preserve the plants in these bed for replanting somewhere else next spring, but I'm not sure what is the best way or time to do this.
I live in interior CT so it's starting to get cold now and won't be too warm when construction is expected to begin. Should I move the plants now, possibly temporarily to my raised vegetable bed, for permanent replanting in the spring (since I'd like to use some of plants around the new addition). Or should I pot them all and keep them in my basement, near a window, for the winter? Or should I leave them and try to retrieve them right before construction, even if it's super early spring? Or are there better options. Thanks for the help.
