Blooms on Calla Lily won’t open

Question

When I bought [2] potted calla lilies, they had open yellow blooms. The blooms have since closed and are dark green. Both plants are loaded with blooms, but they are green and will not open and turn yellow. . . HELP. I have moved it around, used Miracle Grow fertilizer, have it in a bottom drainage pot, water it daily, and mulched the container with cedar chips. What am I doing wrong??

Answer 1

Calla lilies' flowers normally start out green and will gain color as the flower ages. This is normal. As for the buds not opening fully, in addtion to keeping it watered, you can also add some phosphorus, such as bone meal, to the soil.
