Four years ago when I bought my first house I was given a Calla Lily for a house warming gift. I love this flower and want to care for it properly but I feel I am failing miserably. It started out as a small plant and is now MASSIVE (4 feet tall and to full to wrap my arms around) and I have transplanted the small off shoots to the point that I know have half a dozen large plants. The problem is that they seem to 'crumple' on themselves. As if they are simply too tall to bear their own weight. The stalks bend/break and drop. How do I fix this? Plant deeper? Use wooden dowels as support? Is it ever appropriate to cut them back? Your advice is greatly appreciated!
It sounds like your plant needs to be divided.

I have a calla lily in a pot. This is the 2nd year for it and is doing outstanding. It has had over a dozen blooms so far this season. Problem is, the blooms started out to be yellow but now stay green. Everything looks great. Leaves are beautiful, nice green and the blooms are big and strong, just no color.
Your Calla Lily needs more sunlight.

I have a calla lily in a container on my balcony, which was in bloom when I bought it and has continued to bloom for about a month. Now, however, the leaves are growing very tall and the flower stems are only growing an inch or two, hidden by the foliage. Is there something I can do to correct this?
Check the watering, they like to be moist but not sitting in soggy soil.
Try increasing the light but not heat.
Did you fertilize? To much Nitrogen can cause foliage to grow and not the flowers.
Here is a link to verify the growing conditions.
Is it beneficial to cut the blooms to encourage more to grow?
Once the calla flower begins to die, it rolls up into a tube, often turning green on the outside. These spent blossoms should be clipped off through a technique called "deadheading". More information on deadheading can be found in the following article:

They have white on their leaves. They were given to me by a neighbor. I store them under my house, just like she does and bring them out in spring.
This could be powdery mildew from being stored in a damp location.
Treat the plant with Neem Oil.
They also may need more Phosphorous to encourage flowering. Bone Meal is a good way to do so.

My calla lilies' leaves are curling. Why?
Yellowing and curling leaves can indicate watering issues.
Either to much or to little.
Check to make sure the plants are kept moist but not sitting in soggy soil.

Why does my indoor Calla Lily droop? Am I over watering it or under watering? The plant droops if the dirt looks dry. The leaves feel wet. It's very strange. It's an indoor plant.
There could be a few reasons.
Your plant does look a bit leggy. It may need more sunlight. Find the brightest location you have.
Also check the soil. It should be moist not soggy. The first inch or so should dry out before watering again.
