Hello to all,

I live a half-block from the beach in San Diego and have the typical compacted sandy soil. I have been trying to grow Calla Lillies for the past year and continue to have problems with the leaves turning yellow and wilting. Sometimes the entire plant dies back to the ground. They get sun most of the day and I water every other day for about 5 minutes with above ground sprinklers.

I have tried fertilizing and digging down around the plants so they get more water from the sprinklers. Sometimes that seems to work. I recently took some leaves to my local nursery and they told me I am overwatering and "drowning" the plants. I thought Calla's liked water...

Anyhow, I'm confused and not sure what to do. Do I need to amend my soil? If so, what should I use and how do I do that with the plants already in the ground? How often should I water them?

Any help would be much appreciated...thanks!
