Calla Cameo

Yes. Calla lilies, also known as Zantedeschia, grow well in pots indoors or outdoors through the warmer months. Place them somewhere warm and bright, then move tender Calla lilies to a frost-free place before winter.

Calla lily bulbs are bulb-like rhizomes. Start them in pots from early spring, with the growing points facing upwards and just covered with compost. Keep the compost moist while they are actively growing, but never leave the pot standing in water.

Yellow leaves can be normal as a Calla lily finishes flowering and moves towards its winter rest. Yellowing during active growth is more often caused by too much water, poor drainage or cold conditions, so let excess water drain away and keep the plant somewhere warm.

Calla lilies need plenty of bright light, regular watering while growing and a warm position to flower well. A newly planted rhizome may need time to establish. Removing fading flowers also helps the plant direct energy into producing more blooms.

Once the leaves have died back, stop watering and keep tender Calla lily rhizomes dry in a frost-free, preferably dark place until spring. Some hardy arum lilies can stay outdoors in mild areas, but the colourful Calla lilies usually sold for pots need winter protection.
