Zantedeschia aethiopica prefers a semi-shade exposure; avoid direct sun in the hottest hours of the day. They do not resist frost. The soil must be acidic and contain abundant organic matter. Water abundantly so that the substrate never dries out; they are semi-aquatic plants. They do not resist drought. Fertilize with mineral fertilizer every 20 days during the flowering period. They do not need pruning. Dig up the tubers during the dormant period (winter). They are fairly easy growing plants that do not usually present serious pest and disease problems if they do not suffer from drought. They are propagated by division of the tubers in spring. Plant them 15 cm (5.9") deep in large pots. |
