To multiply calla lilies, you can follow a simple process of digging up the rhizomes, dividing them, and planting them in other areas of your garden. This allows you to propagate new plants and expand their presence in your landscape. Let me walk you through the steps.
1. Choose the right time: The best time to divide calla lilies is in early spring or late fall, when the plants are not actively growing or flowering. This allows them to recover more easily from the transplanting process.
2. Prepare the soil: Before digging up the rhizomes, prepare the planting area. Calla lilies prefer well-draining soil with plenty of organic matter. Amend the soil with compost or well-rotted manure to improve its fertility and drainage.
3. Dig up the rhizomes: Carefully dig around the clump of calla lilies, ensuring you don’t damage the rhizomes. Use a garden fork or shovel to gently lift the clump out of the ground. Shake off excess soil to expose the rhizomes.
4. Divide the rhizomes: Examine the clump and locate the individual rhizomes. They are tuberous structures that store nutrients for the plant. Using a sharp, clean knife or garden shears, cut the rhizomes into smaller pieces. Each division should have at least one healthy shoot or bud and a portion of the rhizome.
5. Treat the divisions: To prevent any potential fungal or bacterial infections, it is a good idea to dust the cut surfaces with a fungicide or powdered sulfur. This helps protect the divisions during the healing process.
6. Plant the divisions: Choose a new planting area for each division. Dig a hole deep enough to accommodate the rhizome, ensuring the top of the rhizome is about 2 inches below the soil surface. Space the divisions at least 12-18 inches apart to allow for their growth and spread.
7. Water and care for the new plants: After planting, water the divisions thoroughly to settle the soil and provide moisture for the initial growth. Keep the soil evenly moist but not waterlogged, as calla lilies prefer slightly moist conditions. Mulching around the plants can help retain moisture and suppress weeds.
8. Monitor and maintain: Regularly check the newly planted divisions for any signs of stress or disease. Provide adequate sunlight, as calla lilies prefer full to partial sun. Fertilize the plants with a balanced, slow-release fertilizer according to package instructions to promote healthy growth.
By following these steps, you can successfully multiply calla lilies and enjoy their beauty in different areas of your garden. Remember to be patient, as it may take some time for the divisions to establish and start producing flowers.
