Calla lily bulbs produce the iconic, trumpet-shaped blossoms that connote beauty and grace. Although calla lilies most often are seen in tasteful flower arrangements, they are as well-suited for life in an outdoor garden as they are in a vase. In fact, the delicate-looking calla lily comes from a hardy bulb that is easy to plant and tough to kill.
Choose a spot to plant your calla lily bulbs that provides ample direct sunlight in the morning and partial shade in the afternoon. Avoid planting calla lily bulbs where water collects after a hard rain. Calla lilies need well-draining soil.
Amend the soil if it has not already been prepared for use as a flower bed. Spread 4 inches of organic fertilizer and blend it into the soil. For maximum flower production, do this in the fall to allow the soil time to mature.
Plant calla lily bulbs 2 to 4 inches deep with the side that features the most tubers and eyes facing upward. Cover the bulb with soil and firmly tamp the ground to eliminate air pockets. Neighboring calla lily bulbs should be planted at least 12 inches away.
Water the ground enough to soak the soil.
