Hi, are Picasso and Zantedeschia hardy or do they require lifting for winter/ Thanks M.S.
Hi Mr Salter
Zantedeschia are not hardy and will require protecting over winter.
We advise lifting Rhizomes before the first frosts and store them over winter before replanting them in the Spring (after the risk of frost has passed).
Store Rhizomes in trays of compost in a cool, dark, frost-free location, e.g a garage, shed, warm greenhouse or conservatory.
