The Weeping Blue Atlas Cedar (Cedrus atlantica 'Glauca Pendula') is a stunning conifer known for its graceful, cascading branches and silvery-blue foliage. Its unique form, however, requires some training to maintain its beauty and prevent it from becoming overgrown or unruly. This guide will walk you through the essential techniques for training your Weeping Blue Atlas Cedar.

Understanding Your Weeping Blue Atlas Cedar's Growth Habit

Before you begin training, it's important to understand how this tree grows. The weeping habit is a result of its naturally pendulous branches, which grow downwards. Without proper training, these branches can become very long and heavy, potentially touching the ground or becoming tangled. This can lead to dead or damaged lower branches due to lack of light and air circulation.

Assessing Your Tree's Current State

Take a close look at your cedar. Identify areas needing attention:

Overgrown or tangled branches: These need pruning and shaping.
Bare patches: These may indicate a need for more light penetration.
Weak or damaged branches: These might need removal.

Training Techniques for a Weeping Blue Atlas Cedar

Training a Weeping Blue Atlas Cedar involves a combination of pruning and supporting techniques.

1. Pruning for Shape and Health

Pruning is crucial for maintaining the tree's shape and health. It’s best done in late winter or early spring before new growth begins.

Removing dead or damaged branches: These should be cut back to the trunk or a healthy branch.
Thinning out congested areas: Remove some branches to allow air circulation and sunlight penetration.
Shortening excessively long branches: Cut back long branches to maintain the desired shape and prevent them from touching the ground.
Creating a central leader (optional): Some gardeners choose to establish a central leader by selecting a strong, upright branch and selectively pruning others to encourage its dominance. This can create a more structured weeping effect.

Tools: Use sharp, clean pruning shears or loppers to make clean cuts. Avoid tearing or shredding the bark.

2. Supporting Techniques

Young Weeping Blue Atlas Cedars, especially those with long, heavy branches, may benefit from support.

Staking: Use sturdy stakes to support the trunk and prevent it from bending over.
Branch supports: For particularly heavy branches, individual supports might be necessary to prevent breakage.
Guiding branches: Gently guide branches to encourage the desired weeping shape. You can tie branches to supports using soft material like garden twine. Ensure the ties are loose enough to avoid constriction.

3. Watering and Fertilizing

Proper care contributes to strong growth, making training easier.

Consistent watering: Keep the soil consistently moist, especially during dry periods.
Fertilizing (optional): A balanced fertilizer can promote healthy growth, though it's not strictly necessary.

Common Mistakes to Avoid

Over-pruning: Avoid removing too much foliage at once. This can stress the tree.
Using dull or dirty tools: This can damage the tree and increase the risk of disease.
Ignoring support needs: Failing to support young trees can lead to broken branches.

Maintaining Your Trained Weeping Blue Atlas Cedar

Regular maintenance is key to keeping your Weeping Blue Atlas Cedar looking its best. Perform light pruning annually to remove dead or damaged branches and maintain the desired shape. Continue to monitor for support needs as the tree grows.

With careful attention and regular maintenance, your Weeping Blue Atlas Cedar will reward you with years of beauty and elegance. Remember to always prioritize the health and well-being of your tree throughout the training process.
