Outdoor cultivation of Zantedeschia

When growing Zantedeschia in open ground, a distinction is made between rhizomatous species, such as Z. aethiopica, and tuberous hybrids. Due to the thermophilic nature of the crop, planting in containers that can be buried in the ground is practiced to simplify transport and lifting. A key requirement is high-quality drainage and the use of raised beds to protect against waterlogging, which causes infection by Erwinia, Pythium, and Rhizoctonia pathogens.

Professional agrotechnology involves the use of plastic tunnels to control soil moisture and protect flower stalks from precipitation. Unlike perennials, the cultivation cycle of tuberous species consists of spring planting, summer vegetation, and mandatory lifting before frost. A critically important practice is to keep the foliage after lifting until it naturally wilts to ensure the completion of nutrient translocation to the tuber or rhizome.
