Identification

• Live oaks grow to an average height of 80 feet with a canopy width of 100 feet, according to Clemson University. Often, the long branches droop to the ground. The leaves stay attached to the tree until new ones push them out in the spring, although they may turn yellow.
  
  

Geography

• Live oaks prefer the warm, humid environment of the deep South. They grow wild along coastal areas and are resistant to salty air and soil. While they are most prevalent in the South, they can grow as far north as the coast of Oregon. Live oak trees will thrive in USDA growing zones 7B through 10B, according to the University of Florida.
  
  

Growth

• Live oaks grow quickly at first. If they are properly cared for, they can grow an average of 2 1/2 feet per year, according to Clemson University. Live oaks grow fastest in sunny coastal areas in sandy, well-drained soil. As the trees get older, their growth slows. These large trees can have a trunk diameter of up to 6 feet and can live for 300 years or longer.
