HORTICULTURE

Detailed explanation-1: -These rings can tell us how old the tree is, and what the weather was like during each year of the tree’s life. The light-colored rings represent wood that grew in the spring and early summer, while the dark rings represent wood that grew in the late summer and fall.

Detailed explanation-2: -The underlying patterns of wide or narrow rings record the year-to-year fluctuations in the growth of trees. The patterns, therefore, often contain a weather history at the location the tree grew, in addition to its age.

Detailed explanation-3: -During wet, cool years, most trees grow more than they do during hot, dry years. As a result the tree tends to make wider rings in these years. Drought or a severe winter can reduce tree growth, causing narrower rings.

Detailed explanation-4: -Count the dark rings to calculate the age of the tree. Start in the middle of the stump or cross-section of wood and count the first dark ring you see. Continue counting outwards from the middle ring until you reach the last dark ring. The total number of dark rings represents the age of the tree in years.
