Answer: What fabulous success you have had! Although using a dolly to move them in and out is feasible, finding a spot to keep them in over the winter must be tough. You might consider allowing them to be frosted and thus kill back the tops. Then allow them to go dormant during the winter months by holding back the water. In spring, start them back into growth by watering and placing them in a bright warm location. Alternatively, you could try allowing them to overwinter in the ground where they grew and covered with a generous amount of mulch. If you decide to try this, keep in mind that a sheltered location is best. Either of these methods will result in smaller plants, but make winter care much easier.
