How the Tree Grows 



As" the tree grows older the food which the 

 roots take up and the leaves digest is helping 

 it to grow in height and thickness. Trees grow 

 very little in the winter. It is in the spring that 

 their growth really begins, and in the summer 

 that they grow best. 



When the food comes back from the leaves 

 to the body of the tree, it helps the newer, living 

 wood, the cambium, to add a thin layer of wood 

 to the trunk of the tree. This is like a new coat
