Are calla lilies poisonous? What precautions should I take when handling them?
Yes, all parts of the calla lily plant contain calcium oxalate, which may cause severe irritation and swelling in the mouth and throat if ingested. Keep calla lilies away from children and pets, and wear gloves when handling them to avoid skin irritation.
How do I overwinter calla lilies in colder climates?
After the first frost, when the foliage begins to wilt, dig up the rhizomes and allow them to dry in a cool, dry place. Store the rhizomes in a paper bag or cardboard box in a cool (45-50°F or 7-10°C), dry place until the danger of frost has passed in spring.
