Any calla lily experts out there familiar with growing them successfully in central Florida (Tampa to be exact)? I've bought several from Lowes recently, the pink ones not the white. I've searched and searched the internet and some say let them dry out between waterings, some say keep them wet, some say full sun and some say partial sun.

My first one basically rotted down to the bulb, clearly too much water. These last two, the leaves are slowly turning yellow. At first i was keeping them in partial shade and letting the soil dry between watering. Since the leaves started turning yellow i thought I'd introduce them to morning sun afternoon shade and moist soul.

I dont know what im doing wrong. I love these flowers and want to grow them so badly. I even ordered bulbs and planted them in containers at the end of April. They haven't started to sprout yet but when/if they do i want to know enough not to kill them too.
