I planted some calla lilies on the south side of my house--part sun, part shade--about 5-7 years ago. I thought they were annuals, and we enjoyed their many blooms. The next year, they came up again with only a layer of fallen leaves for mulch and protection. They've been spreading and coming back every year since then, even after bitter cold winters and sometimes two feet of snow here in Kansas City, MO. I feed my flower beds only once in early spring and once in late summer-early fall. I water them only when they're dry. These are growing in and around evergreen spreaders. My question is, I love them dearly but wonder how many years they can be expected to continue.
Probably for quite some time. I think you may have a micro-climate on the side of your house, most like due to the house itself. The south side of the house is the warmest, and your house collects that heat, which keeps the ground there warmer than the rest of your yard. The callas are kept alive because of this.
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:

Where can I transplant a calla lily plant in my garden?
They like full sun to partial shade and like rich loose soil. This article may help you:

I bought a calla lily in a pot a week ago, and the leaves have all turned yellow.
There are many reasons this can happen. This article will help you pinpoint what is causing it with your plant:
