Green Calla Lily Blooms
My calla lilies will bloom but the blooms are green and will not open. Any suggestions on what they may be lacking? Thanks.

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, they likely need more water. Increase your watering. They should be watered at least daily and twice a day if the temps are over 80 F, especially if they're in containers. You can also add some phosphorus, such as bone meal, to the soil.
