This week I would like to focus my garden column on the topic of tree biology. Aborist Phil Frazee has compiled these interesting notes for all us tree lovers out there.
In the area of root physiology and its relationship to developments in the tree canopy, Phil assures us that many of the problems that manifest themselves in the tree canopy crown begin below. Many instance of decline, loss of vigour, deadwood development, or death of trees can be traced to damage of the root system.
