Tree Pruning/Tree Trimming

Tree Pruning or trimming is recommended with an emphasis on aesthetic considerations in addition to structural integrity. Tree trimming consists of the removal of dead, dying, diseased, interfering, objectionable, obstructing, and weak branches, as well as selective thinning to lessen wind resistance.

1. When tree pruning or tree trimming all cuts shall be made as close to the trunk as possible without cutting into the branch collar.

2. All branches that are too large to support with one hand shall be precut to avoid splitting or tearing of of the bark. When necessary, ropes or other equipment should be used to avoid damage to structures or landscape.

3. Treatment of wounds with wound dressing or paints has not been shown to be effective in preventing or reducing decay, or insect infestation.

4. The use of climbing spurs (hooks, gaffs, spikes, irons) is not an acceptable work practice for trimming work on live trees. Sharp tools shall be used so that clean cuts are made at all times.

5. Tree trimmings (hangers) shall be removed from the crown of the tree upon completion of pruning.

6. When trimming, trees that are susceptable to serious infectious diseases should not be pruned at the time of year which the pathogens causing the disease or the insect vectors are most active. Example: Only trim Pines in the Winter, they bleed a lot of sap in the summer and could lead to insect infestation.
