What does research tell us about pruning in arboriculture?
Tree care is founded on sound science. In addition, questions are often answered with experiments. Before the 1980s, it was common practice to remove branches directly against the trunk. This came with the introduction of chainsaws. Cutting "flush" became the accepted practice. Once the branch was removed, the wound was covered with a sealant. Arborists were admonished for leaving any wound unpainted.
In current practice, arborists sever a branch just at the edge of the branch collar and avoid flush cuts. We also leave wounds uncovered. Research provided the basis for changing these long-standing techniques. Across a wide range of tree species in several countries, wound dressings neither enhanced closure nor reduced decay or discoloration.
With a certified arborist on the crew at all times, we provide the most up-to-date and scientifically supported care for your trees.
