Q.What’s wrong with my calla lily?
I planted a calla lily this spring but after a few weeks the flowers turned green. It’s been in this state for 2 months now. What’s my problem?

There's no need to worry about the green color. On some types this is the normal progression for calla lilies. These flowers do that as they mature and begin producing seeds. You can cut them off or leave them be.
Other possibilities include poor pollination, which can result in green color and too much light can turn the spathes green.
