The age of a mature pear tree can be estimated by measuring its diameter 4.5 feet above the ground (measure the circumference and divide by 3.14). Multiply the diameter (in inches) by 3 to get the approximate age.
What is the average lifespan of a pear tree?
It is also especially vulnerable to fire blight, a common bacterial disease among pears that kills off branches and makes the tree less hardy overall. So as far as the average lifespan of pear trees go, again depending on variety and climate, anywhere from 15 to 20 years is possible, given adequate growing conditions.
Can you tell how old a tree is without cutting it down?
The girth of a tree can be used to estimate its age, as roughly a tree will increase it’s girth by 2.5cm in a year. So, simply measure around the trunk of the tree (the girth) at about 1m from the ground. Make sure you measure to the nearest centimetre. Then divide the girth by 2.5 to give an age in years.

How do you date a tree?
Tree-Ring Dating
The most common, most accurate way to find the age of a tree is to count the number of rings visible when their trunk is cut horizontally. Each year, most trees add an extra layer of growth to their trunks. Over time, their trunks get thicker and thicker.
How many years is each ring on a tree?
one year
Each ring marks a complete cycle of seasons, or one year, in the tree’s life. As of 2020, securely dated tree-ring data for the Northern Hemisphere are available going back 13,910 years.
How can you tell the age of a tree by counting rings?
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.
Should I trim my pear tree?
