What is it when Calla lily's leaves turn yellow, please?
Yellowing leaves could be watering issues, either too much or too little.
Here is a link with more information on care.
I have always wanted to try my hand at calla lily. I planted 3 plants about a month ago. Shortly after, all the blooms closed. I assumed it was shock but they haven't improved. Both leaves and flowers still look very healthy except the flowers will not open. Any thoughts?

Should I cut back the Calla Lilies now that they have finished blooming? I have divided them periodically but never lifted them during the winter months. They are very healthy and beautiful when in bloom. I have seen some gardens that have cut them back, but I would want to know if that's wise, before I attempt it.
Let the leaves naturally die back to feed the bulbs.
Here are a couple of great links for you.

I can see a green bulb looking thing inside of the flowers. Are they new bulbs? If not, what is it?
Your Calla Lily flowers are forming seed pods.

About a month ago I planted a few calla lily plants but now they're falling over. The leaves all look green and healthy. What is causing this? Are they not planted deep enough? I'm a newbie at calla lily so any and all help will be greatly appreciated.

Two years ago my beautiful yellow calla lily had 13 blooms on it at once. Last year, only one. This year the greenery sprouted and grew a bit then died. Is there anything I can do to try to save it? It gets plenty of water and bright sunlight.
This is an indication that your plant needs to be divided.

I wintered over calla lilies in their orig pot over the winter as directed. I now have a beautiful pot of leaves and not one single flower. What have I done wrong?
Lush leaves and no flowers usually indicates to much Nitrogen. You can add phosphorous.
Bone Meal is a great way to do this.
A very crowded pot could also need dividing. This can be done after they bloom, so let's get them flowering!
