I have a full healthy batch of Calla Lilies in my flower bed but they are no longer blooming. In the spring and early summer, they did great at blooming, but for the past month or so they get the initial trumpet look but do not color. I live in Oklahoma and believe the zone number is 7. I have never taken them up since planting them about 3 years ago. Any help would be appreciated.

It is likely that your calla lily simply considers itself done blooming for the year. Each calla typically only blooms during a set period of the year and then focuses on producing seed and storing energy for next year.
