Propagation by Seeds

Calla lilies can be propagated by seeds, though this method requires patience and attention.

Collecting Seeds

* Allow the flower to fully develop and form a seed pod.
* When the seed pod turns brown and dry, harvest it and extract the seeds.
* Remove the seed pod’s outer covering to access the seeds within.

Sowing Seeds

* Fill a seed tray with a well-draining seed starting mix.
* Sow the seeds thinly on the surface of the mix and press them down gently.
* Keep the soil moist but not waterlogged.
* Provide warmth and light by placing the seed tray in a warm, sunny location or under grow lights.

Germination

* Germination typically occurs within 14-21 days.
* Once the seedlings have developed their first set of true leaves, they can be transplanted into individual pots.
* Continue growing the seedlings in a warm, sheltered environment until they are strong enough to be planted outdoors.

Pros and Cons

* Pros:
* Produces genetically diverse plants.
* Relatively inexpensive method.
* Cons:
* Time-consuming and requires patience.
* Seedlings may not retain the characteristics of the parent plant.

Division of Rhizomes

Rhizome division is an effective method for propagating mature calla lily plants.

Steps

* Dig up the mature plant during the dormant season (late summer to early fall).
* Remove any soil from the rhizomes.
* Cut the rhizomes into sections, each with at least one growing point (eye).
* Allow the cut sections to dry and form calluses for a few days before planting them.

Planting

* Plant the rhizome sections in well-drained soil.
* Position the eyes facing upwards and cover them with a thin layer of soil.
* Keep the soil moist but not soggy.
* New shoots should emerge within a few weeks.

Pros and Cons

* Pros:
* Maintains the characteristics of the parent plant.
* Produces multiple new plants quickly.
* Cons:
* May disturb the parent plant, especially if it is not fully mature.
* Requires a mature plant to propagate.

Propagation by Corms

Calla lilies can also be propagated by corms, which are modified stems that store nutrients.

Steps

* Dig up the mature plant during the dormant season and separate the corms from the rhizomes.
* Select healthy corms that are firm and free of disease.
* Plant the corms in well-drained soil.
* Position the corms with the pointed end facing upwards and cover them with a thin layer of soil.
* Keep the soil moist but not soggy.

Pros and Cons

* Pros:
* Produces multiple new plants quickly.
* Corms can be stored over winter for planting in the spring.
* Cons:
* May not maintain all of the characteristics of the parent plant.
* Corms may not be available for all varieties of calla lilies.

Propagation by Bulbils

Some calla lily varieties produce bulbils, which are small, pea-sized structures that grow along the rhizomes.

Steps

* Remove the bulbils from the parent plant.
* Plant the bulbils in a well-drained soil mix.
* Keep the soil moist but not soggy.
* New plants should emerge within a few weeks.

Pros and Cons

* Pros:
* Produces multiple new plants quickly.
* Maintains the characteristics of the parent plant.
* Cons:
* Not all calla lily varieties produce bulbils.
* Bulbils may be small and difficult to handle.

Tissue Culture Propagation

Tissue culture propagation is an advanced technique that involves growing plant cells in a sterile laboratory environment. This method is often used for commercially producing calla lilies and other plants.

Steps

* Tissue samples are taken from the parent plant.
* The samples are placed in a nutrient-rich medium and grown under controlled conditions.
* New plantlets are formed and multiplied in the culture.
* The plantlets are eventually transplanted into soil and grown to maturity.

Pros and Cons

* Pros:
* Can produce a large number of plants quickly and efficiently.
* Can be used to propagate rare or endangered varieties.
* Cons:
* Requires specialized equipment and expertise.
* Can be expensive.

Tips for Successful Propagation

* Use clean and sharp tools to avoid disease transmission.
* Provide the proper growing conditions for each propagation method.
* Be patient, as some methods may take several months to produce new plants.
* Label the propagated plants to keep track of their variety and origin.
* Keep the newly propagated plants sheltered and protect them from extreme temperatures until they are well-established.

Conclusion

Propagating calla lilies is a rewarding endeavor that allows you to enjoy the beauty of these captivating plants for years to come. By mastering the various methods outlined in this guide, you can successfully multiply your collection and share the joy of these elegant flowers with others. Whether you choose to propagate by seeds, division, corms, bulbils, or tissue culture, the key is to provide the proper care and attention to ensure the thriving of your cherished calla lilies.
