The Importance of Urban Landscape Pruning

Pruning is not only for health, but also for aesthetics and safety

By Heather Vigil - February 12, 2020

The month of February is not only deemed, the month of love, but it is also the last month before spring arrives.  So, here at American Arbor Care, your Denver Tree Care specialists wanted to a moment to discuss the importance of regular pruning rotations for your trees and shrubs.  Our arborists are more than happy to visit your property annually if you ever have any questions if your trees or shrubs are in need of pruning.

It is important to note, that when one of our certified arborists visits your property to evaluate the need for pruning we take into consideration the overall health of the plant material.  Every pruning cut made to a tree or shrub does not only change the appearance of the plant, but changes the overall growth patterns of trees and shrubs and has lasting effects.  

We follow the International Society of Arboriculture and ANSI A300 Standards of pruning specifications.  These pruning standards assist us in determining when to prune, the type of pruning we will be completing, and how aggressive we can prune.  Important to note: we do not top trees nor do we make flush cuts during our regular pruning operations.  These styles of pruning are gravely dangerous to the plant's overall health and growth patterns.

Some of our criteria include the following:

*Reducing the risk of tree or branch failure
*Raising skirts to provide clearance to structures, sidewalks, and streets
*Increase sun penetration through the canopy and reduce wind resistance
*For flowering trees it increases the flower/fruit production
*To increase or decrease screening/views
*Improving the aesthetics 

We customize and balance the pruning needs for each property based upon the needs of the plant material and the client request(s).  Our pruning standards (along with any other special notations) include:

*Structure Prune and Shape-we recommend this style of pruning for young trees.  The timing of this operation is recommended around 5 years after the tree has been planted.  Pruning rotation can vary upon growth rate and species.
*General prune and shape-This is a full pruning.  This pruning operation looks for dead, dying/diseased, crossing/interfering branches, things the tree by 10-15%, and prunes long ends back to natural form.  Dependent upon the species, this pruning rotation for shade trees is completed once every 5-7 years and for ornamental species (without disease) every 2-4 years.
*Deadwood only or deadwood up 2/3rds- this operation only removes deadwood from the tree or shrub.  The deadwood up 2/3rds is a pruning operation completed on pines and spruce.  Pruning rotation timing is dependent upon species.
*Prune and shape-this pruning operation targets a few thinning cuts and shaping of the tree.
*Crown reduction-this pruning operation is mainly targeted for ornamental trees.  Its focus is for trees that are mis-shapen or overgrown.

If you have an questions or concerns with your trees and shrubs please feel free to call us to request one of our certified arborists to visit your property.
