Why do my calla lily leaves and flowers drip water? It is a slow drip.
This means that the plant has pests, either scale or aphids. The water is actually honeydew from these pests. These articles will help:

I have just planted a few plants in my front flower bed, and the leaves are turning yellow and it looks like the stem of some of the leaves and flowers are possibly rotting at the soil line. Could you tell me what could be causing this to happen?
This is a condition called soft rot. This article will help you:

We have a calla lily that was given to us in a container. Should we move it out of the sun? It was doing very well, but the past few days the leaves have begun to yellow some and the blooms are turning brown. It does get morning and early afternoon sun; and in Arizona, the temperature is beginning to rise.
Moving it out of the sun will help. It needs more water and a shadier spot will reduce its water needs some.
I got a calla lily plant about 3 weeks ago. It looks like the flowers are beginning to die off. I know they need a 'dormant' period. My question is: Is there a certain time of the year they should be dormant? With this being summer, it is concerning me.
They normally go into dormancy in the winter, but ones that are in containers can be forced into dormancy anytime. They may need more water and light to avoid going into dormancy, or you can just let them go and then enjoy another round of blooms indoors later in the year. This article will help:

My calla lilies bloom green, no color in the flowers. What am I doing wrong? When I bought them they had color. Then as the summer went on they came up green and stayed that way.
Nothing wrong. Calla lily flowers often start out green and develop their color as they grow. The color should appear shortly.
