Zantedeschia grow best in full sun or partial shade and in organically rich, moist, well-drained soil. They are well suited for bog or marsh gardens, for planting near ponds and streams, or as border plants or for containers. When to plant: any time between Feb and June, but only after any danger of frost has passed.
IN THE GROUND
- Choose a sheltered position and add some well-rotted organic matter before planting.
- Plant the Zantedeschia tubers 10cm deep and about 30cm apart.
- Set the tubers with the growing tips facing up. Cover them with soil and water as needed. Mulch to keep down weeds and conserve soil moisture.
- Provide consistent moisture during the growing season and do not allow the soil to dry out.
- Calla Lilies can grow as tall as 2 to 4 feet, so a tall, narrow pot is better container than a wide, shallow one.
- Place the tuber so it is lying horizontally, with the eyes facing upwards.
- Cover the bulb loosely and give it enough water just to dampen the soil.
- Set your tall pots in a sunny spot where they will get a bit of shade in the afternoon and fill the saucer under the pot with water.
- Feed with a balanced liquid fertiliser once a month until the flowers have faded.
- Mulch annually in autumn with well rotted garden compost or manure.
- Snip off blossoms as they start to fade, using clean and sterilised gardening shears.
