You can start lilacs by digging up a shoot in late spring or early summer and replanting it. Here's a more detailed breakdown of the process:
Starting Lilacs from Shoots (Suckers)
Lilacs commonly produce shoots, also known as suckers, from their base. This is a relatively easy way to propagate new lilac bushes.
Timing
- The best time to propagate lilacs from shoots is in late spring or early summer.
Procedure
-
Locate a Shoot: Identify a healthy-looking shoot growing from the base of the main lilac plant.
-
Carefully Dig: Gently dig around the shoot, being careful to keep as many roots intact as possible.
-
Sever the Shoot: Separate the shoot from the main plant using pruning shears or a sharp knife, ensuring it has some roots attached.
-
Planting:
- In a Container: Plant the shoot in a container filled with damp potting soil.
- Directly in Garden Soil: Alternatively, you can replant it directly into well-draining garden soil.
-
Rooting Hormone (Optional): Dusting the bottom third of the shoot with rooting hormone powder can encourage root growth, but it's not strictly required.
-
Watering and Care: Keep the soil consistently moist but not waterlogged. Protect the new plant from harsh sunlight until it becomes established.
Summary
Starting lilacs from shoots is a straightforward method involving digging up rooted suckers from the base of an existing plant and replanting them. Timing (late spring/early summer) and careful handling of the roots are key to successful propagation.
