What is tree trimming vs. tree pruning?

The difference between tree trimming and tree pruning comes down to the intention and strategy in the two methods. Pruning often refers to the removal of branches deemed unnecessary or hazardous, and this process helps stimulate growth. Tree trimming focuses on removing overgrown branches. But this process can also help the tree receive more moisture and light. 

A professional might recommend pruning and trimming at different times of year to stimulate growth or leverage the tree’s dormant period to slow new sprouting.
