Calla lilies, scientifically known as Zantedeschia, have the ability to self-propagate through various methods. One of the most common ways is through division of their rhizomes or rooting structures. This method involves separating the clumps of calla lilies into individual plants, allowing them to grow independently.
To propagate calla lilies through division, you can start by digging up the clump of plants during their dormant period, which is typically in late fall or early spring. Carefully remove the clump from the soil, making sure to avoid damaging the rhizomes. Gently separate the individual plants, ensuring that each division has a healthy portion of rhizome and several growing points or buds.
Once divided, you can replant the calla lilies in their desired locations. Make sure to choose a well-draining soil and a sunny or partially shaded spot. Dig a hole deep enough to accommodate the rhizome and place it in the hole, ensuring that the growing points are facing upwards. Cover the rhizome with soil, firm it gently, and water thoroughly.
Another method of calla lily propagation is through seeds. However, it’s important to note that seed-grown plants take longer to flower compared to those propagated through division. If you’re patient and enjoy the process of growing plants from scratch, you can collect the seeds from mature calla lily flowers. Allow the seed pods to fully ripen and turn brown before harvesting the seeds. Sow the seeds in a well-draining seed-starting mix and keep them moist until they germinate. Once the seedlings have grown a few inches tall, you can transplant them into individual pots or directly into the garden.
It’s worth mentioning that calla lilies can also self-propagate naturally in certain conditions. Sometimes, the plants will produce small bulb-like structures called offsets, which are clones of the parent plant. These offsets can be detached and replanted to grow into new plants. However, this method of propagation is less predictable and may not occur consistently.
In my personal experience, I have successfully propagated calla lilies through division. I found that the best time to divide them is during their dormant period when the plants are not actively growing. By carefully separating the rhizomes and replanting them, I was able to create new calla lily plants that eventually bloomed beautifully.
To summarize, calla lilies can self-propagate through division of their rhizomes or rooting structures, as well as through seed germination. Division is the most common and reliable method, resulting in faster flowering plants. However, if you are patient and enjoy the process of growing plants from seeds, you can also propagate calla lilies that way. Regardless of the method you choose, providing the right growing conditions and proper care is essential for the success of your propagated calla lily plants.
