Tchukki Andersen, staff arborist for Tree Care Industry Association says, “Save your tree care pruning for when the tree is actively growing in the early spring or completely dormant in the winter months.”
Licensed arborists are pruning trees every day year-round without a lot of detrimental effects, however, tree service professionals know more about how to care for the health of a tree. They understand its stages and processes such as dormancy and new growth.”
