Simple Tips To Keep Blooming Calla Lilies Fresh All Summer
By SAKSHI KHAITAN
Calla lilies (Zantedeschia spp.) last nearly two weeks when cut. In gardens, they bloom for almost a month, offering stunning colors like white, burgundy, lilac, and gold.
Deadheading calla lilies doesn't induce more blooms, but it keeps them neat and appealing. They also won’t waste their energy in setting seeds, promoting healthier bulb growth.
Clipping calla lilies for arrangements and deadheading are similar but differ in timing. For arrangements, clip as flowers open; for deadheading, wait until they discolor or droop.
Use shears to cut dead flowers at the base. Remove yellowing foliage and keep watering and fertilizing until the rest withers to enhance plant vigor and build sturdier rhizomes.
Calla lilies are classified into two categories: white-flowered Zantedeschia aethiopica and colorful Zantedeschia hybrida. They thrive in high light but not high temperatures.
Hybrids prefer day and night temperatures below 75 and 65 degrees F, while white cannas prefer below 70 and 60 degrees F. They’re best in fairly sunny or partially shaded gardens.
