How to prune atlas cedar

Late winter to early spring while dormant, before new growth; or midsummer for minor tidying. Make all cuts at the branch collar using clean, sharp tools. On young Atlas Cedars, identify the strongest central leader and remove competing stems flush to the trunk before they thicken. On mature trees, limit intervention to dead-wood removal and any crossing branches causing rubbing damage.

Rarely; leader selection on young trees annually, dead-wood removal as needed. Atlas Cedar develops a broad, spreading, picturesque form over decades and needs very little pruning. Remove dead or dying branches when found. Young trees may produce competing leaders — select one and remove rivals early. Do not shear or attempt to reduce the canopy; cuts into bare old wood will not regenerate and scars are permanent.
