Transplanting day lilies can enhance your garden’s design or improve their growing conditions. These versatile perennials are generally resilient, but proper technique and timing are key to a successful move. Follow this step-by-step guide to ensure a smooth transplant and continued thriving.
1. Choose the Right Time for Transplanting
- Optimal Timing: The best time to transplant day lilies is in late summer or early fall, after they have finished blooming but before the first frost. This timing allows the plants to establish their roots before the colder winter months.
2. Prepare the New Planting Site
- Site Selection: Day lilies prefer full sun to partial shade. Choose a location that receives at least 6 hours of direct sunlight each day for optimal blooming. However, they can tolerate some shade, especially in hotter climates.
- Soil Preparation: Day lilies thrive in well-draining soil that is rich in organic matter. Amend the soil with compost or well-rotted manure to improve fertility and drainage. They prefer slightly acidic to neutral soil (pH 6.0 to 7.0).
3. Prepare the Day Lilies for Transplanting
- Watering: Water the day lilies thoroughly a day or two before transplanting to hydrate the plant and make it easier to lift. Avoid watering immediately before the transplant to prevent overly wet soil, which can be heavy and difficult to work with.
- Pruning: Lightly trim back the foliage to reduce the plant’s size and make it easier to handle. Remove any dead or damaged leaves.
4. Dig Up the Day Lilies
- Digging: Use a garden fork or spade to dig around the day lilies, starting about 6-8 inches from the base of the plant. Carefully lift the plant with its root ball intact, trying to preserve as many roots as possible.
- Dividing: If the day lilies have become overcrowded, this is a good time to divide them. Separate the clumps into smaller sections, ensuring each division has a healthy set of roots and shoots.
5. Transplant the Day Lilies
- Planting: Place the day lilies in the prepared planting hole. The hole should be about the same depth and width as the root ball. Space multiple plants about 12-18 inches apart to allow for their spreading growth.
- Depth: Position the day lilies so that the crown (where the leaves meet the roots) is level with or slightly above the surrounding soil surface. Cover the roots with soil and gently firm it down to eliminate air pockets.
6. Post-Transplant Care
- Watering: Water the transplanted day lilies thoroughly to help them settle in. Keep the soil consistently moist but not waterlogged during the initial establishment period. Regular watering will encourage healthy root development.
- Mulching: Apply a layer of mulch around the base of the plants to retain moisture, regulate soil temperature, and suppress weeds. Use organic mulch such as wood chips, bark, or straw.
7. Monitor and Maintain
- Observation: Watch the transplanted day lilies for signs of stress, such as wilting or slow growth. Ensure they are adjusting well to their new location and address any issues promptly.
- Fertilization: After the plants have had time to establish, you can apply a balanced, slow-release fertilizer in early spring to support healthy growth and blooming.
8. Long-Term Care
- Pruning: Continue to remove any dead or diseased foliage throughout the growing season. Regular deadheading of spent flowers will promote additional blooming and maintain the plant’s appearance.
- Pest and Disease Control: Keep an eye out for common pests and diseases, such as aphids or fungal infections. Treat any issues with appropriate methods to ensure the health of your day lilies.
By following these steps, you can successfully transplant day lilies and provide them with the optimal environment for continued growth and vibrant blooms. Proper care before, during, and after the transplanting process is crucial for ensuring your day lilies thrive in their new location.
