How to trim a Cedar Tree

Knowing when the best time to prune cedar trees is, it becomes the most significant thing to do in the way of getting the job done. The tree should be trimmed at the end of the winter season or at the beginning of spring, just before the tree starts to develop new growth. It is during this time of its peak activity when the tree will be given enough time to heal, promote new growth, and therefore it will be able to be pruned. Cedars that are pruned in the late summer or autumn are more likely to be damaged and become diseased. Minor maintenance can still be performed throughout the year.

Cedar Tree Trimming

3. Removing dead or diseased branches
