Our 45-year-old Twin Maples were pruned by a utility company 18 months ago, with one tree cut severely and now deteriorating, while the less-pruned tree remains healthy. Should the crew have applied a sealant to the cut branches to prevent deterioration?
We do not use sealant any more as of about a decade ago. The reason that we don't use it, is that it hinders the trees ability to form what is called Callus Tissue over the injury. The best way to make certain that your trees are not severely pruned by utility companies is to have an Arborist inspect. Click here to make an appointment.
