How to Transplant a Calla Lilly

Calla lily plants can reach up to 36 inches tall once they are established. The plants are often grown as houseplants, but they thrive best outdoors in sunny locations. The flowers typically do not bloom until the summer weather arrives. When you are ready to transplant a call lily, remove it from the ground carefully to avoid disturbing the roots. Remove calla lily rhizomes from the ground in cold climates in the fall when they stop blooming. The lilies are then transplanted in the spring once the threat of frost passes.

Instructions

    • 1

      Insert a garden spade or fork into the ground 2 to 3 inches away from the calla lily rhizomes. Wiggle the spade to remove the rhizomes. Lift the calla lily rhizomes out of the ground and lay them on several sheets of newspapers.

    • 2

      Divide large calla lily rhizomes into two plants or more. Cut the rhizomes with a sterile knife. Each rhizome section must contain roots.

    • 3

      Dig holes in the new location that are 4 to 6 inches deep and 12 inches apart. Make the holes twice as large as the rhizomes. Loosen the soil with a garden fork and place each calla lily rhizomes into a new hole. Plant it at the same soil level as its previous location.

    • 4

      Fill the holes with soil and press down on lightly to remove air pockets.

    • 5

      Water the calla lilies to dampen the soil. Continue to water the lilies with 1 inch of water a week, unless adequate rainfall occurs.

    • 6

      Apply a 2-inch layer of mulch around the lilies to keep the soil moist.

    • 7

      Apply a 5-10-5 fertilizer to the calla lilies in the spring. Follow the fertilizer instructions carefully.
