For those so inclined, pruning season is now open.
There are many reasons people pick up a saw or loppers to prune up their trees in young stands. The most common motivations I hear are accessibility, aesthetics and fire resistance/prevention. Even pruning up just a single- eight foot “lift” can serve any or all of those objectives.
People want to be able to walk freely around the place without fighting through dense brush the whole way. So many prune to open trails or corridors. This allows them to get to favorite spots more easily, or just get around and see how things are doing. It lets them enjoy the property more (daily walks or bird watching) and also to more easily take care of tasks like spot spraying invasive weeds. Pruning a whole block of trees improves not just access but opens up the line of sight. It quickly changes the look and feel of a young stand and gives the stand an open aesthetic that many people like.
