We experienced a 2 year drought here. The nurseries were clearing out plants because they couldn't keep up with the watering. I was able to pick up some great plants throughout the summer and a few at the end of growing season which is October in Minnesota. I keep a space for wintering over plants. If they are getting root bound I will take them out of the pot, clean up the root ball and plant it. If not root bound, any potted plant buried in the ground seems to do just fine until Spring. Plants that I grow in decorative containers always winter over in a plain pot which I bury. I may amend the dirt in the Spring if needed. I have found that most plants are fairly tough. I have had irises in a pot with no dirt for 2 years and I see today they are still green...
