In order to keep trees at a suitable size for their location, crown reductions can be performed.
A crown reduction is most commonly performed to keep a tree from encroaching on services or buildings, or even on views!
Reductions are also a viable means of aesthetically rejuvenating a specimen, particularly after severe storm damage.
This involves carefully pruning the entire crown in a way which retains the natural shape of the tree while reducing its size. Great care is taken when pruning back to growth points to ensure minimal likelihood of dieback or rot.
"Pulling into form" is best described as a partial crown reduction, a technique we employ on trees that have become mis-shapen over the years. This is normally carried out simply to maintain the beauty of cherished trees, while making minimal changes to their form.
