The pin oak is a popular choice of tree for landscaping and it has a distinct branching pattern that separates it from the other oaks. Unlike most oaks which have heavy horizontal branches, the pin oak has many slender branches which arch out and hang down; these main branches have pinlike branchlets, hence the name “pin oak”. In addition, the pin oak is very susceptible to pH levels in the soil and cannot tolerate high pH soils which cause chlorosis (yellowing).
