To take care of calla lillies in the garden, you need to choose a place that gets sunshine in the morning. In the afternoon it is appropriate for them to have some shade, particularly in areas that have hot summers. The soil should be moist and rich with organic material.


Plant the rhizomes of calla lillies in this rich soil a foot or two apart and four to six inches deep. Care of calla lillies requires that you keep track of the temperatures of your garden during the winter. If you are in zones 8 or 9, you can either dig them up during freezing weather and keep them protected, or you can mulch them with bark or straw. Cooler climates require you to dig up the rhizomes.

When you get your rhizomes dug up, they need to have the loose soil knocked off. Next they need to be allowed to dry out in the sunshine for a few days. The best winter storage location for the care of calla lillies is a dry spot with a consistent temperature of about 55 degrees.
