It is possible to transplant your calla lilies to the garden for the spring, summer, and fall, as long as you take proper care of them before the winter. You can plant your lilies outside when the temperatures begin to rise and there's no more chance of frost. Calla lilies that are planted outside need lots of bright but indirect sunlight. Somewhere that gets partial shade is ideal, or an area that gets filtered or indirect light. Before planting, till the soil in the garden bed to loosen it. Spread 1 to 2 inches (2.5 to 5 cm) of organic matter, such as compost or organic mulch, over the garden bed. Work the organic matter into the soil with a tiller to improve drainage and provide the calla lily with plenty of nutrients. Dig a 3- to 4-inch (8- to 10-cm) hole in the ground for the bulb. Gently dig the bulb from the pot with your hands and place it into the hole. Cover the bulb with fresh soil. If you're transplanting more than one calla lily, space them 12 inches (30 cm) apart.
