In warm climates where calla lilies are winter hardy (zones 8-10), the rhizomes may be left in the ground to bloom again the following summer. The plants may need to be divided every few years to keep them blooming well. In cooler areas (zones 3-7), calla lilies are usually treated as annuals, with new bulbs planted each spring.
When do calla lilies bloom?
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. These are perennial plants, as you already know, so they are likely to bloom in the late spring or during the early months of summer.
The next thing we asked ourselves was, when to fertilize calla lilies?
This is what my research found. when calla lilies are planted in the spring, flowering is usually delayed until late summer. During the growing season, calla lilies appreciate a monthly dose of liquid fertilizer. This is especially important when they are grown in containers.
Can you plant calla lilies in Zone 8?
ZONE: Calla lilies are winter hardy in zones 8-10. In colder areas they can either be grown as annuals or can be dug up in the fall and stored indoors for replanting the next spring. Reference the USDA Hardiness zone map here. WHEN TO PLANT: Calla lilies should be planted in the spring after all danger of frost has passed.
We should dig a little deeper! they are hardy than most other spring-planted bulbs, often surviving the winter even in Zones 6 and 7 when mulched in the fall. Calla lily rhizomes are typically planted during the spring season. Choose a planting location that had well-drained soil and receives full to partial sun for best results.
Can you grow lilies in Zone 9?
Lilies, amaryllis, callas and gladiolus…these are but a few common zone 9 bulbs, but there are also some truly unique and crazy plants that will thrive in those regions. Try a voodoo lily or a spider-like Ismene (Peruvian daffodil). Or perhaps a pineapple lily will make you wonder at the world.
Can calla lilies survive winter in the ground?
The calla lily is a native African plant that isn’t even described as a true lily. According to the University of Illinois, the Calla lilies aren’t even actual lilies. These are herbaceous flowering plants that are unable to survive the winter when left out in the ground.
