drooping calla lilies

Asked June 28, 2017, 3:50 PM EDT

I first planted calla lilies in the spring and the blooms on the straight flowers are beautiful. Unfortunately some of the blooms are drooping and almost touching the ground. Should I cut the drooping flowers or just let them go their way. Also, some of the straight flowers are closing up and losing their color. Any suggestions would be appreciated

Calla lilies (genus Zantedeschia) are not terribly easy to grow here.
They are native to North Africa and grow in swampy marshland which tends to dry up during the summer months, at which time the leaves die and they go dormant.
Some people grow them as houseplants here, allowing them this rest period after they bloom early in the year- often from late spring to early fall.
These were evidently forced into bloom for our growing season.
Do you have them in the ground or in pots?
We are not sure how long their bloom period is in the ground here, so either they are finished, or they are unhappy. This is likely as
they are marsh plants, and during the growth phase that has leaves, they need to be watered plentifully so that the soil is kept thoroughly moist.
That is hard to do unless you are using it as a pond edge plant. In fact, they can be put in a pond or water several inches deep.

While they are actively blooming, they should be fertilized weekly.

Light: They like bright light with some direct sun. The reason they are probably better for use as houseplant than outdoors is because they like average room temps, and temps above 70 can shorten the life of the flowers and leaves.

Once the plant is finished blooming, it will enter the rest period.
Unless you plan to try and get it growing again as a houseplant, the rhizomes will die in our winters.
