How can you tell the age of the tree?

Today topic how can you tell the age of the tree? If you look at a tree stump you will see a series of rings. Each one represents one year’s growth. So by counting the rings you can find the age of the tree. A tree grows only during the spring and summer. In spring the cambium produces large xylem cells. But gradually, as summer passes, the new xylem cells become smaller. The difference between small, late summer cells becomes smaller. The difference between small, late summer cells and large spring cells shows up clearly as a growth of ring. Therefore the number of growth rings shows how many seasons have passes since the tree first began to grow.
