Calla lilies, arum lilies, or Zantedeschia aethiopica, are tropical plants that originated from South Africa. They are easy house plants that give elegant, white flowers.
Calla lilies grow best in warm climates and humid conditions. But they can also be winter hardy in USDA Hardiness Zones 8 to 10.
Calla lily bulbs should be protected from the dangers of first frost. Consider growing them as indoor plants before winter starts, or store the dried bulbs in air-tight containers.
Grow them indoors near a southern-facing location in winter months, where they can enjoy a little sun.
Use a humidifier or pebble tray to maintain a high humidity levels during winter. Avoid placing them on a dry place.
The best time to plant calla lilies is in early spring. But if you want to start it early for the growing season, grow it indoors in late winter with LED lights.
Avoid feeding them during winter months because they grow dormant. Water them only when the topsoil feels dry.
