Arum lilies like a well drained but moist soil. They tolerate a pH range from 5.5 - 7.5 and like a sunny to semi-shaded position. If you grow calla lilies in a rich, well fertilized soil you will have great results.
Your callas will start flowering during spring until the summer. During this time it is very important that you feed and water the plants regularly! You can use a general purpose organic fertilizer for this. Once the plants have finished flowering stop the feeding and watering. The arum lilies now enter their dormant phase.
If you are growing callas in a container you can repot them during July. Take the root ball out of the pot and shake all the loose soil off the roots. You can also divide the rhizomes during this procedure. Replant the bulbs with fresh potting soil and over-winter them at 50-60 degrees F (10-15 degrees C).
