Calla lilies are elegant and popular plants known for their striking flowers and lush foliage. Propagating them through divisions is an effective way to create new plants and expand your garden. This guide provides step-by-step instructions on how to successfully regrow calla lilies from divisions.
Understanding Calla Lily Divisions
Divisions involve separating a mature calla lily rhizome into smaller sections, each capable of growing into a new plant. This method is best performed during the plant’s dormant period, typically in early spring or late fall. Proper division ensures healthy growth and minimizes damage to the plant.
When to Divide Calla Lilies
The ideal time to divide calla lilies is just before the active growing season begins. Look for signs such as:
- Foliage that is yellowing or dying back
- Large, mature rhizomes with multiple growth points
- Cool weather with moist soil conditions
Tools and Materials Needed
- Garden spade or sharp knife
- Clean pruning shears
- Gloves
- Fresh, well-draining soil or potting mix
- Containers or planting beds
- Optional: Rooting hormone
Step-by-Step Guide to Dividing Calla Lilies
Follow these steps to successfully divide and regrow your calla lilies:
1. Prepare the Area
Choose a cloudy day or work during early morning or late afternoon to avoid stress on the plant. Prepare your tools and select a suitable location for planting the divisions.
2. Dig Up the Rhizomes
Carefully dig around the base of the calla lily to loosen the soil. Lift the rhizome gently, avoiding damage to the roots and shoots.
3. Clean and Inspect
Remove excess soil and inspect the rhizome for healthy sections. Look for firm, plump areas with visible eyes or growth points. Discard any rotted or diseased parts.
4. Divide the Rhizome
Using a clean knife or pruning shears, cut the rhizome into sections. Each section should have at least one eye or growth point. Optionally, dip the cut ends in rooting hormone to encourage root development.
5. Plant the Divisions
Plant each division in well-draining soil or pots filled with moist potting mix. Bury the rhizome about 2-3 inches deep, with the eyes facing upward. Space the divisions adequately to allow growth.
Caring for Your New Calla Lilies
Provide proper care to ensure healthy growth of your newly divided calla lilies:
- Watering: Keep the soil consistently moist but not waterlogged.
- Light: Place in bright, indirect sunlight for optimal growth.
- Fertilizer: Feed with a balanced liquid fertilizer every 4-6 weeks during the growing season.
- Temperature: Maintain warm temperatures between 65°F and 75°F (18°C – 24°C).
Troubleshooting Common Issues
Watch out for common problems such as:
- Root rot: Caused by overwatering; ensure proper drainage.
- Yellowing leaves: May indicate nutrient deficiency or overwatering.
- Pest infestation: Look for aphids or spider mites and treat with appropriate organic solutions.
Final Tips for Success
Patience is key when propagating calla lilies from divisions. With proper timing, tools, and care, you can enjoy beautiful new plants in your garden or home. Regularly monitor your plants and provide consistent care to ensure healthy growth and vibrant blooms.
