Useful Information

Why is tree spiking harmful to trees?

If tree work needs to be performed on a tree whose appearance is important to you, always insist that tree services climb the tree using ropes or ascend with an aerial lift rather than using climbing spikes. Spikes cause damage to the cambium (trunk) of a tree and could leave trees susceptible to disease and insect infestation which could lead to the costly removal of a tree.
