The Bur Oak is the most wide-ranging oaks native to Canada, growing all the way from Saskatchewan to New Brunswick. Although it tolerates a wide variety of soil and climate types, it grows best in deep soils in rich bottom lands. Although the crown is rounded, it is often irregular in shape even when grown in open conditions. The roots system consists of a deep tap root an a number of deep wide spreading lateral roots which help make the Bur Oak not only drought resistant but also one of the most wind firm.
