Calla Lilies grown in your garden should bloom without much fuss. However, if they don’t bloom, it could be attributed to several reasons. If you notice that the plant’s foliage is lush and grows quickly or spot brown leaf segments, then it is highly likely that excess nitrogen has stopped your flowers from blooming.
Cool, wet conditions contribute to the formation of fungal spores. When the warm weather hits, they bloom and spread causing all kinds of mayhem on a wide variety of plants. Soft rot is most common on calla lilies. This forms from spores in the soil that attack the bulb and stems of the plant.
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.
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.
When do calla lilies bloom?
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.
Another frequently asked question is “Do calla lilies go dormant in the winter?”.
You can simulate a dormancy period in winter by not watering your calla lily and storing it in a cool, dark location for about two months. Outdoor calla lilies will die back naturally and go dormant when they need to. If your calla lilies have properly rested but still refuse to bloom, they could be lacking phosphorus.
Is a calla lily a true lily?
Calla lilies are not true lilies. They are in the same family as the Jack-in-the-pulpit. The flowers are not what they seem either. The flower’s petals are called the spathe. The spathes are modified leaf structures, which fold around the spadix.
Is it normal for Calla lilies to turn green?
It is completely normal to have green spathes on some varieties of young calla plants. The buds start out green or streaked with green and turn color as they open and mature. This natural occurrence is not considered among the calla flower problems, as it will fix itself in time.
