This year (in April), for the first time I planted seven Calla Lily tubers. For references, I live in Southern California close to the Coast. Six of my seven tubers did produce foliage and flowers. The last one did not make it.

Lately, I have noticed that a couple of plants have lost all their foliage whereas the others have not. So here are my questions:

- should I expect (as it is usually the case with bulbs) a total die-back of my plants at this time of the year?

- should I dig up the tubers and replant them next year?

Thanks for your help and input.
