The secret language of trees

Most of the forest lives in the shadow of the giants that make up the highest canopy. These are the oldest trees, with hundreds of children and grandchildren. They check in with their neighbors, share food, supplies and wisdom gained over their lives, all while rooted in place. How do they do this? Camille Defrenne and Suzanne Simard explore the vast root system and intricate communication of trees.
