Zantedeschia ‘Picasso’ with its special white and purple colour can be planted both indoors and outdoors. Plant the tuber in a pot with good soil. Then place Zantedeschia in full light immediately and water it regularly. first the leaves and then the striking flowers. After the danger of night frost has disappeared, Zantedeschia can also be planted outside. Plant them 10 cm. deep in humus-rich, well-drained soil in full sun. Zantedeschia likes to grow in fairly moist soil. When planting in flower pots and planters, always use new potting soil. In a garden with fairly moist soil, Zantedeschia can be combined nicely with hostas, among other things. Give Zantedeschia plenty of water in the summer, the soil may be kept slightly moist at all times. For potted plants, place a saucer under the pot and always leave a layer of water in it during dry periods. Zantedeschia is not resistant to frost. That is why it is advisable to grow plants in a pot and to overwinter them frost-free. Keep the potting soil on the dry side in winter. Water more in early spring and put Zantedeschia outside again in spring (after the last frost).
