Calla lilies are elegant and striking plants that can be divided to promote healthy growth and create new plants. Dividing calla lilies is a simple process that can be done every few years to rejuvenate the plant and increase your garden’s beauty. This step-by-step guide will help you learn how to divide calla lilies effectively.
When Is the Best Time to Divide Calla Lilies?
The ideal time to divide calla lilies is in early spring, just as new growth begins to emerge. This allows the plant to recover quickly and establish itself before the growing season. Avoid dividing during the dormant winter months or when the plant is actively flowering.
Tools and Materials Needed
- Garden spade or shovel
- Sharp knife or pruning shears
- Gloves
- Garden compost or mulch
- Water
- Bucket or container for dividing
Step-by-Step Instructions
1. Prepare the Area
Water the plant thoroughly a day before dividing to soften the soil and reduce stress on the plant. Clear the area around the calla lily to give yourself enough space to work.
2. Carefully Dig Up the Plant
Use a garden spade or shovel to gently loosen the soil around the base of the plant. Carefully lift the entire clump out of the ground, trying not to damage the rhizomes or roots.
3. Divide the Rhizomes
Shake off excess soil and examine the rhizomes. Using a sharp knife or pruning shears, cut the clump into sections, each with at least one healthy growth point or eye. Ensure each division has enough roots to establish itself.
4. Plant the Divisions
Plant each rhizome division in well-draining soil, about 2-3 inches deep. Space them apart to give each enough room to grow. Water thoroughly after planting.
5. Care and Maintenance
Apply a layer of mulch around the newly planted divisions to retain moisture and suppress weeds. Keep the soil moist but not waterlogged. Fertilize with a balanced fertilizer during the growing season for optimal growth.
Tips for Successful Division
- Always use clean, sharp tools to prevent disease.
- Divide calla lilies every 3-4 years for best results.
- Handle rhizomes gently to avoid damage.
- Label divisions if planting in different areas or containers.
Dividing calla lilies is a rewarding process that can rejuvenate your plants and expand your garden. With proper timing, tools, and care, you can enjoy healthy, beautiful calla lilies for years to come.
