The delicate flowers of calla lilies add a touch of refined beauty to any garden. Better yet, laying down calla lilies is one of the simpler planting tasks found in many gardens. Calla lilies grow from bulbous rhizomes planted in suitable soil and propagate by spreading more rhizomes throughout the area. One calla lily planted in a garden often turns into several over the course of a year or two. While calla lilies thrive in USDA hardiness zones 8 to 10, gardeners in colder climates can allow them to bloom outdoors in the summer then store the bulbs indoors over winter.
Difficulty: Moderately Easy
Select a suitable site to plant the calla lilies. Situate the plants in an area with partial shade to full sun and moist soil rich in organic matter. If the ideal conditions are not present, try planting them elsewhere — calla lilies grow in most soils.
Prepare the area to receive the calla lily bulbs. Dig holes 1 inch deep. Leave 2 feet of space between holes.
Lay calla lily bulbs down in the bottom of the dug holes. Refill the holes with the displaced soil.
Moisten the soil immediately after planting. Water the ground as necessary to keep the soil around the bulbs moist but not wet. Calla lilies enjoy moist conditions.
Calla lilies are toxic. Keep the plant out of the reach of small children.
