I have overwintered these Dragon Wings for two years. I can't believe that they are still doing so well. I simply cut them back and place them in a corner of our garage where they get northeast light exposure in the morning from a nearby window. I water occasionally.....but not too much. I don't want them to start growing too soon. Last winter was very mild here and they did start to grow....very spindly....and I was concerned that they would die when I put the pots out on the porch in the spring. I added some rich potting soil and some soil conditioner and dug it into the first few inches, working carefully around the plants. I trimmed back the longest stems because they were so weak. I waited a couple of weeks to fertilize for fear that it would shock them. It took them a while to firm up and green up and sprout new stems, but just look at them now!
