Alstroemeria, also known as Peruvian lilies or lily of the Incas, are beautiful flowering plants that can multiply and spread over time. These plants have tuberous roots, which means they can be easily propagated through division. This process involves separating the clumps of tubers and replanting them to create new plants.
To propagate Alstroemeria, follow these steps:
1. Timing: The best time to divide and propagate Alstroemeria is in early spring or late fall when the plants are dormant. This allows them to recover and establish themselves before the growing season begins.
2. Prepare the soil: Choose a well-drained location with fertile soil for planting the divided Alstroemeria. Amend the soil with organic matter, such as compost, to improve its texture and fertility.
3. Dig up the plant: Carefully dig up the entire clump of Alstroemeria using a garden fork or shovel. Be gentle to avoid damaging the tubers. Lift the clump out of the ground and shake off excess soil.
4. Divide the tubers: Separate the tubers by gently pulling them apart or using a clean, sharp knife to cut through the clump. Each division should have at least three to five healthy tubers with intact roots.
5. Trim and prepare the divisions: Trim any damaged or dead roots and foliage from the divisions. This helps reduce stress and promotes new growth. If the divisions are large, you can also cut them into smaller sections to create more plants.
6. Plant the divisions: Dig holes in the prepared soil that are wide and deep enough to accommodate the divisions. Space the divisions about 12 to 18 inches apart to allow for their growth and spread. Place each division in a hole, making sure the tubers are positioned horizontally and the growing tips are facing upwards. Fill the hole with soil, gently firming it around the divisions.
7. Water and care: After planting the divisions, water them thoroughly to settle the soil and remove any air pockets. Keep the soil evenly moist but not waterlogged during the first few weeks to help the divisions establish roots. Provide the plants with regular water and mulch around them to conserve moisture and suppress weeds. Alstroemeria prefer full sun to partial shade and can benefit from a balanced fertilizer application in early spring.
8. Monitor and maintain: Keep an eye on the newly planted divisions for signs of growth and ensure they are getting adequate water and sunlight. Alstroemeria are hardy plants, but they can be prone to pests and diseases like aphids or root rot. Regularly inspect the plants and take appropriate measures if any issues arise.
By following these steps, you can successfully propagate Alstroemeria and expand your collection. Remember to be patient, as it may take some time for the divisions to establish and start blooming. Enjoy the beauty and abundance of these lovely flowers in your garden!
