Trees undergo spurts in growth in the spring and summer months while becoming somewhat dormant in the fall and winter months.When a tree is cut down, these periods are exhibited in a cross section of the trunk in the form of rings.A tree's growth rate changes in a predictable pattern throughout the year in response to seasonal climate changes, resulting in visible growth rings.Each ring marks a complete cycle of seasons, or one year, in the tree's life.Simply counting the number of rings will give one a fairly good idea of the age of the tree.

Some types of relative dating techniques include climate chronology, dendrochronology, ice core sampling, stratigraphy, and seriation.In his Trattato della Pittura (Treatise on Painting), Leonardo da Vinci was the first person to mention that trees form rings annually and that their thickness is determined by the conditions under which they grew. S., Alexander Catlin Twining (1801–1884) suggested in 1833 that patterns among tree rings could be used to synchronize the dendrochronologies of various trees and thereby to reconstruct past climates across entire regions.During the latter half of the nineteenth century, the scientific study of tree rings and the application of dendrochronology began.Choosing Fruit Trees Buying Fruit Trees Community Q&A Savoring fruit picked from a tree on your own land is an accomplishment that requires research and hard work.Before buying fruit trees, you must first learn about local climate conditions and what types of fruit trees will thrive on your property, then buy healthy trees from a local nursery or garden center.
