How to Prune Black Lace Elderberry Into a Tree

The Black Lace Elderberry (Sambucus nigra ‘Eva’) is a stunning deciduous shrub that can be pruned into a tree-like form, adding an elegant touch to any garden or landscape. Pruning it into a tree shape not only enhances its aesthetic appeal but also allows for easier maintenance and better air circulation. Here’s a step-by-step guide on how to prune Black Lace Elderberry into a tree:

1. Choose the right time: The best time to prune Black Lace Elderberry is during late winter or early spring before new growth begins. This allows the plant to recover quickly and minimizes the risk of damaging new shoots.

2. Start with a young plant: It’s easier to train a young Black Lace Elderberry into a tree shape. If you already have an established shrub, you may need to remove some lower branches to create a more tree-like form.

3. Select a central leader: Identify the strongest and most upright stem to serve as the central leader. This will be the main trunk of your tree.

4. Remove competing stems: Remove any competing stems that are growing close to the central leader. This will ensure that the main trunk has enough space to grow upwards without interference.

5. Prune for a desired height: Decide how tall you want your Black Lace Elderberry tree to be. Prune the central leader to the desired height, making a clean cut just above a bud or lateral branch.

6. Create a well-spaced scaffold: Choose 3-5 lateral branches that are evenly spaced around the main trunk. These branches will form the scaffold of your tree. Prune them to a length that allows them to grow outward and not compete with each other.

7. Remove excessive growth: Remove any additional branches that are growing too close to the central leader or scaffold branches. This will help maintain the tree’s shape and structure.

8. Regular maintenance pruning: As your Black Lace Elderberry tree grows, it’s important to continue regular pruning to maintain its shape and encourage new growth. Prune any dead, damaged, or crossing branches during late winter or early spring.
