Only certified tree surgeons/arborists who have actually understood the market and recognize the physiology of a tree can perform specific tree pruning techniques. 3 of the techniques we have actually mastered are the different types of Crown shaping, Espalier and French Pollarding that are accomplished by cutting annual shoots back to their heads, producing a well-filled, tight-lined appearance. Active pruning of trees will also be based on giving the tree the best odds to regrow and restore from the resulting injury.
