Calla lilies are elegant and versatile plants that can add beauty to any garden or indoor space. Over time, they may become crowded, leading to reduced flowering and overall health. Dividing and replanting calla lilies is an effective way to rejuvenate the plants and promote vigorous growth. This guide will walk you through the process step by step.
When to Divide Calla Lilies
The best time to divide calla lilies is in early spring, just as new growth begins. This allows the plants to establish themselves before the growing season peaks. Avoid dividing during the dormant winter months or when the plant is actively flowering.
Tools and Materials Needed
- Sharp garden spade or knife
- Gloves
- Clean pruning shears
- Well-draining potting mix or garden soil
- Large pots or planting beds
- Watering can
- Rooting hormone (optional)
Steps to Divide Calla Lilies
Follow these steps to successfully divide your calla lilies:
1. Prepare the Area
Choose a cloudy day or perform the division early in the morning. Water the plant thoroughly a day before to soften the soil and reduce stress during division.
2. Dig Up the Plant
Carefully dig around the base of the calla lily, loosening the soil with a spade or garden fork. Gently lift the entire clump out of the ground, being cautious not to damage the rhizomes.
3. Separate the Rhizomes
Inspect the clump for natural divisions. Use clean, sharp pruning shears or a knife to cut apart the rhizomes, ensuring each division has at least one growth point or eye. Discard any diseased or rotten sections.
4. Treat the Divisions
If desired, dip the cut surfaces in rooting hormone to encourage healthy root development. Allow the divisions to dry for a few hours before planting to form a callus over the cut surfaces.
5. Replant the Rhizomes
Plant the rhizomes about 4 to 6 inches deep in well-draining soil or pots filled with a rich potting mix. Space them 12 to 18 inches apart to give each plant room to grow. Water thoroughly after planting.
Caring for Replanted Calla Lilies
Provide consistent moisture, but avoid waterlogging. Calla lilies thrive in moist, well-drained soil and partial shade to full sun. Fertilize every few weeks with a balanced fertilizer to promote healthy growth and flowering.
Tips for Successful Division
- Always use clean tools to prevent disease.
- Divide only healthy, vigorous rhizomes.
- Allow cut surfaces to callus before planting.
- Water regularly, but do not overwater.
- Mulch around plants to conserve moisture and suppress weeds.
Dividing and replanting calla lilies can refresh your garden and produce more stunning blooms. With proper timing and care, your plants will reward you with vibrant flowers year after year.
