How to Prune American elder?

(Sambucus canadensis)

American elder, also known as American black elderberry

This deciduous shrub, known for its large clusters of white flowers and small, purplish-black berries, benefits from regular pruning to maintain vigor and shape. Prune american elder in early spring before new growth begins. Use rejuvenation pruning by cutting one-third of the oldest stems to the ground annually. Also, remove dead or diseased wood and thin out crowded areas to improve air circulation. Pruning not only promotes healthier, more robust plants but also enhances berry production.

What Are the Benefits of Pruning American Elder?

Pruning american elder encourages vigorous growth and aids in maintaining its desired shape. By selectively removing parts of the plant, it promotes a sturdier structure and more robust health.

What Is the Best Time for Pruning American Elder?

Spring

Pruning american elder in early spring is advantageous as it allows the removal of any dead or damaged wood from the winter season before the plant initiates its rapid growth phase. This timing also ensures that the energy american elder has stored for new growth can be directed into producing strong, healthy shoots, improving the overall vigor of the plant. Additionally, since american elder flowers on new wood, pruning just before the growing season will not negatively impact the flowering and subsequent fruiting as it would if the plant were pruned after new growth has developed. Early spring pruning also typically coincides with a period when the threat of severe cold has passed, reducing the risk of frost damage to fresh cuts and new growth which can compromise the health of american elder.

How to Prune American Elder

Step1: Timing Pruning for Dormant Season

Choose the proper time to prune american elder, which is in late winter or early spring before new growth begins, when the plant is still dormant.

Step2: Sterilize Tools to Prevent Disease

Sterilize your pruning tools with rubbing alcohol or a 10% bleach solution to prevent the spread of diseases.

Step3: Prune Dead Wood and Angle Cuts

Begin by removing any dead wood. Make clean cuts at a slight angle, about 1/4 inch above a bud that faces outward to promote an open growth habit.

Step4: Remove Diseased Branches to Healthy Wood

Identify and remove any diseased branches next. Cut them back to healthy wood, ensuring the cut is at least a few inches below the diseased section to remove all infected material.

Step5: Eliminate Suckers for Tree-Like Structure

Look for suckers, which are vigorous vertical shoots that grow from the base or roots of american elder. Prune all suckers back to ground level to maintain a clear stem and encourage a more tree-like form.

Step6: Prevent Damage by Removing Crossing Branches

Check for crossing or rubbing branches, and remove them to prevent wounds and subsequent disease entry points. Select the weaker branch or the one that contributes least to the desired shape for removal.

Step7: Thin Crowded Areas for Air Flow

Thin out crowded areas to improve air circulation, which helps to reduce the likelihood of disease. Remove some of the older canes, cutting them back to the ground to stimulate new growth.

Step8: Shape Plant by Trimming Unbalanced Branches

Finally, shape american elder if necessary, by shortening overly long or unbalanced branches. Prune back to a bud facing the direction you wish new growth to take, keeping the overall desired shape of the plant in mind.

Step9: Dispose of Pruning Debris to Reduce Pests

Clean up all pruning debris from around american elder to minimize the chance of disease and insect infestations.

Step10: Water and Mulch Post-Pruning

After pruning, water american elder if the soil is dry and apply a layer of mulch to conserve moisture and provide nutrients as it decomposes.
