Bareroot plants can be safely kept out of the ground for several months if properly cared for. Woody and fleshy rooted plants store and keep well. Wait until the plants leaves have dropped in the fall and then dig the plants up after a hard freeze, but before the ground is frozen. Carefully wash as much soil as you can off of the rootball with a garden hose. Place the roots in moist paper or sphagnum moss. Seal the roots and moss in plastic bags and keep them in place where the temperature ranges from 34 to 40 degrees. Keeping that temperature means placing them in a refrigerator in most cases. The bareroot plants will keep fine until you are ready to plant them in the spring. Roses, hydrangeas, and small shrubs can be kept over winter bareroot. Literally thousands and thousands of plants are dug and planted every year in the nursery industry. So, if you are a homeowner and you want to move, use the same methods that nurseries use and take your favorite plants with you.
