Here is a tree prune Kelley did a week ago in Cambridge, Massachusetts. This illustrates the need for proper care and pruning of your trees for their health and your safety. A branch broke off months ago and was not properly smoothed. As you can see, the end is quite jagged and rough edges tend to retain quite a bit of moisture. This can easily lead to tree rot and compromise a tree’s health and stability. You can see where the rot started to creep into the trunk of the tree; this can cause all kinds of tree health problems (much like an uncleaned or untreated injury to a person!), and physical safety issues for pedestrians and property. Take a few minutes to look around your trees for similar breaks such as this one, so proper maintenance can prevent more severe issues down the road.
