How to Split a Calla Lily Plant
To split a calla lily plant, dig up the entire plant, gently separate the rhizomes, and cut them into sections with at least one healthy shoot and root system. Replant the sections in well-draining soil, water thoroughly, and keep them in a shaded area until new growth appears.
Understanding Calla Lilies
What are Calla Lilies?
Calla lilies are herbaceous perennial plants that are native to southern Africa. They are known for their large, trumpet-shaped flowers that come in a range of colors, including white, yellow, pink, and red. Calla lilies are also characterized by their glossy, green leaves that are shaped like arrowheads.
Why Split Calla Lily Plants?
Splitting calla lily plants is necessary to ensure healthy growth and prevent overcrowding. Over time, calla lilies can become too large for their current pot or garden bed, which can lead to stunted growth and reduced flowering. Splitting calla lily plants allows them to have more space to grow and thrive.
When to Split Calla Lily Plants?
Best Time to Split Calla Lily Plants
The best time to split calla lily plants is in the spring or fall, when the plant is not actively growing. This allows the plant to recover from the shock of being split without being under additional stress from growth or flowering.
Signs that Indicate Splitting Calla Lily Plants
Signs that indicate it is time to split calla lily plants include overcrowding, reduced flowering, and stunted growth. If the plant has outgrown its pot or garden bed, it is time to split it to ensure healthy growth.
Steps to Split Calla Lily Plants
Preparation
Before splitting calla lily plants, gather the necessary tools and materials, including a sharp knife or garden shears, a clean pot or garden bed, and potting soil. It is also important to water the plant thoroughly a few days before splitting it to ensure it is well-hydrated.
Removing the Calla Lily Plant from the Soil
To remove the calla lily plant from the soil, gently dig around the base of the plant with a trowel or garden fork. Once the plant is loose, carefully lift it out of the soil, being careful not to damage the roots.
Separating the Calla Lily Plant
Once the calla lily plant is out of the soil, use a sharp knife or garden shears to separate the plant into smaller sections. Each section should have at least one healthy rhizome and a few leaves.
Replanting the Calla Lily Plant
After separating the calla lily plant, replant each section in a clean pot or garden bed filled with fresh potting soil. Water the newly planted sections thoroughly and place them in a location with bright, indirect light.
Caring for Split Calla Lily Plants
Watering and Fertilizing
Water split calla lily plants regularly, keeping the soil moist but not waterlogged. Fertilize the plants every two weeks with a balanced fertilizer to encourage healthy growth and flowering.
Light and Temperature Requirements
Split calla lily plants prefer bright, indirect light and temperatures between 60-75°F. Avoid placing them in direct sunlight or in areas with extreme temperature fluctuations.
Preventing Diseases and Pests
To prevent diseases and pests in split calla lily plants, ensure they are planted in well-draining soil and avoid overwatering. Keep an eye out for common pests, such as spider mites and aphids, and treat them promptly with insecticidal soap.
Conclusion
Splitting calla lily plants is necessary to ensure healthy growth and prevent overcrowding. By following the steps outlined in this article, you can successfully split your calla lily plant and care for the newly separated sections. With proper care, your calla lilies will continue to bloom and thrive for years to come.
