The removal of dead, diseased and broken branches, as well as the inspection of any cavities and other structural irregularities.
Removal of branches to provide vertical clearance, usually from buildings or traffic.
Often it is possible to prune the top off of one or more of the co-dominant stems. This causes the remaining stems to become more dominant. Over time, and sometimes with repeated applications, the co-dominance can be outgrown.
Usually performed on plants which have been sheared, it is the process of eliminating competing leaders and congested lateral growth in order to get back to a typical arboreal appearance and habit of growth.
Pruning to redevelop structure of severely pruned, vandalized or damaged trees.
Crown Reduction Pruning* (NOT Topping)
This is recommended only in cases in which future breakage is likely, such as with trees of declining health or after the loss of much of the crown in a storm. Making healthy trees smaller is at best the beginning of an expensive maintenance plan, at worst folly.
Removal of branches to create a view through tree canopies.
