I have very prolific and healthy Calla Lillies but every year I have the same issue. (3rd summer)

They start out a beautiful and vibrant yellow only to gradually turn green in week 2-3. They still look healthy but the spathes are all turning green and therefore do not show up. I was told it could be an excess of nitrogen. I have added bone meal but so far it hasn't helped.

Bone meal does not help with too much Nitrogen. It means that you might be fertilizing too much. With using bone meal, you just switched the type of fertilizer.
While bone meal adds phosphorus and not nitrogen, it just might be adding to the problem of too much fertilizer in general.

Thanks. I've never fertilized them before adding the bone meal. That was a suggestion from a local nursery owner but I'll hold off adding any more.
He also suggested it might just be their natural aging process but it seems to be happening too early in the spathe life cycle for that. Maybe I'm wrong. I'm certainly no expert.

Welcome!

Its just the natural aging of the flower. No matter what color they start, eventually they turn green. I think staying yellow for 2 or 3 weeks is good.

Thanks for the information. Should I cut the green ones to encourage more blooms?

Why not wait until they either collapse or turn brown?
Just because they turn green, they are still pretty.

If you let them turn green, eventually they will bend to the ground and dispurse whatever seeds have developed and grow new plants.
