Q.Calla lillies
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!
Here is some more information.
