I am new to having one of these plants, and recently purchased it in may 2009. On the label it says lift the tubers in autumn after the leaves have died down. on your care instructions it tells you to split the roots. Please can you advise me as I'm confused?

What to do with Zantedschia overwinter

Reply from Kathy C

Hi, Sharon,
It does sound a bit confusing but both pieces of advice are technically correct though all dependent upon where you live and how involved you want the dividing process to be. If you live in a very cold area where the ground usually freezes at some point in winter, then you would definitely want to lift the plant. The label that came with your plant it tells you to lift the tubers - might be misleading since 'Picasso' actually has tuberous rhizomes - similar and just as easily lifted. If you are in an area with milder winters, protect the plant with a deep mulch. If you need to divide (which does not need to be done every year), do so in spring.I knew of many Zantedeschia planted in front gardens in my neighbourhood in London. No one ever lifted them or mulched them and they did fine but, admittedly, they were in a sheltered, relatively warm winter place each time. I suppose to be technically precise, the instructions on this site should say 'Divide rhizomes in spring' which involves cutting them into pieces, which each piece having at least one strong bud. You can do this even if you have lifted and stored the rhizomes. Keep them in sand at a minimum temperature of 15C until the buds begin to swell. Divide the rhizomes, put them back in the sand at the same temperature until they root and then you can plant or pot them up. If you don't lift the rhizomes, divide in spring and replant immediately. Hope this makes sense and let me know what you decide to do.

Zantedschia

Thank you for your reply. I have planted the lillie in a tub it is sheltled over the winter months. Alternatively can it be stored in the garage over the winter to prevent frost damage? Do I need to water it over the winter months?
