Why is tree trimming significant? Trees are the ornaments of our garden, and homes for various birds, squirrels, and different critters. Trees epitomize growth and life, giving us harmony, solace, shade, and shelter. When we consider trees seriously, we preserve their magnificence and protect the animals that refer to them as "home." Tree trimming may appear to be a minor detail in the grand plan of garden care, however, it is surprisingly fundamental.
