How to train a weeping blue atlas cedar

In order to obtain the desired cascading or weeping form, the branches of a blue atlas weeping cedar (Cedrus atlantica ‘Glauca Pendula’) are often shaped and guided during training. This is a step-by-step instruction on how to train a weeping blue atlas cedar:

  1. A young weeping blue atlas cedar with a supple and flexible structure is the best option. Compared to older, more established trees, younger trees are simpler to train.
  2. Choose an appropriate planting location: Weeping blue atlas cedars like full sun to moderate shade and well-draining soil. Pick a spot where there is enough room for the tree to expand and cascade without being obstructed.
  3. Create a reliable support system: Place a reliable trellis or other support system close to the tree. This will help the branches acquire their habit of weeping by acting as a guide and a support.
  4. Start your training during the dormant season, which is usually in late winter or early spring, to prune for structure. To build a sturdy foundation, start by removing any broken or crossed branches.
  5. Determine the major branches: Choose the major branches that will make up the basic framework of the weeping shape. From the stem, these branches should branch out at regular intervals.
  6. Branches may be attached to the support structure by gently bending them in that direction and securing them with twine or soft ties. Give the branches room to hang freely over the support.
  7. Maintain desired shape: As the tree matures, keep guiding and anchoring the branches to the framework to ensure that they have the intended weeping shape. Make sure the ties are not excessively tight on a regular basis to avoid damaging the branches.
  8. Maintenance pruning: Remove any potential robust upright branches by doing routine maintenance pruning. These sprouts need to be removed right away since they might obstruct the weeping form.
  9. Monitor growth and make required adjustments: Keep an eye on the weeping blue atlas cedar’s development and alter the training as needed. To keep the ideal shape, keep guiding and securing the branches.
  10. Keep calm: It takes time and attention to train a weeping blue atlas cedar. The tree may need a few years to fully establish its weeping behavior. Over time, consistent upkeep and care will assist in achieving the ideal form.
