If your calla lilies fail to bloom, it may be because of three reasons below, because there aren’t many factors that may cause calla lilies not be able to flower:
Too much nitrogen
Shortage in water
Shortage in sunlight.
Moreover, why is my calla lily drooping?
We discovered the most common reason for a drooping calla lily is lack of water . Calla lilies have high water needs. Always water outdoor calla lilies deeply and thoroughly when you water them. A nice long, slow trickle with a soaker hose allows the plant to soak up more of the water than a drenching blast.
Why are my calla lilies not blooming in pots?
While the same things that affect calla lilies planted in the ground can also affect calla lilies planted in containers, there is a more common reason that container grown calla lilies do not bloom. This reason is that they do not get a dormant period in order to prepare for a blooming season.
Once the calla lily plant has stopped blooming, stop providing water to it. Allow it to go bone dry. The foliage will die back and the plant will appear to be dead. Place it in a cool (not cold) dark place for two months. After this, bring it back out into the light and resume watering it.
The typical calla lily bloom time is in the summer and fall, but for many calla lily owners this time may come and go without a sign of buds or flowers from their calla lily plant. This is especially true for gardeners who grow their calla lilies in containers.
What factors affect calla lily growth and flowering?
However, you should know that there are several factors that influence their growth and flowering. The flowering period of the calla lily depends on the temperature, the amount of light that the plant receives, and the kind of calla lily that you are using.
