Question
I have two plants that I have outside.  The leaves are turning brown.  I understand that I have to dig these up in the fall and then replant in the spring is that correct.

Answer
Sandra,
 When the foliage turns yellow or dies due to the frost, carefully dig up the large rhizomes by loosening the roots gently with a fork or spade. To avoid the damage of the roots, dig several inches back from the base of the plants. Lift the bunch of roots and soil together. If you accidentally cut or break the fleshy structure, then the diseases can enter through the wounds easily. The plant will then rot while in storage.

Remove the soil. Cut the stems and foliage back 2 to 3 inches. Then wash gently any remaining soil with water hose. If you want to recycle the soil, then place a few bunches of calla lilies on a mesh screen, which is laid across a container. Wash the soil into the container.

The curing period should be short. Leave the rhizomes air dry in a room or area away from direct sunlight or drying winds for one to three days, depending on the temperature. Then put the bulbs in a paper bag that is filled with sphagnum peat or vermiculite. Store them in a cool and dark room such as attic or basement, which is away from any heating equipment. Always maintain the temperature between 50 and 55 degrees Fahrenheit with the help of a room thermometer. This will create the conditions for the calla lilies to be ready for replanting in the following spring.

When spring comes, cut the rhizomes into parts. Make sure that each part contains an eye or a growing point on it. Allow the cut surfaces of the rhizomes to dry for a few days before planting them. This allows the wound to form a scab before you subject it to any harmful organisms that are present in the soil.
