When talking about trees there are always comments to make based on cultivar or specie, age, season, weather and site. Various factors will periodically cross my mind as being potentially very useful to people owning, or caring for, trees within my geographical area of practice. Depending on circumstances of the moment, I will offer pertinent suggestions for learning more about trees and their care. Understanding a little bit about trees (and woody plants in general) is an excellent point of beginning.
