Swampscott, MA Tree Trimming is an art and science. It requires an understanding of species characteristics and growth habits so that we can enhance their natural forms. Trim your tees with the focus on lasting health, appearance, and future growth. The first step is to identify the main goal before breaking out the tools. Examples include: removal of broken, dead, hanging, or diseased branches, shade and light management, clearance from structures or paths, management of shape and size, promotion of flowering, etc. Then we proceed at appropriate time of year and plan a frequency of trim which may be a few times a year or not for many years.
