Knowing a tree’s age is an integral component of tree care and management. It helps you determine how fast a tree grows, how long it will live, and whether you need to cut it down. Many people say that you can simply tell the age of an old tree by counting the number of rings in the wood.
That means you’ll need to cut the tree down. What if you want to know a tree’s age without having to cut it down?
In this blog post, Katy’s reliable tree service company explains how to tell the age of a tree using three methods. Keep reading for more information.
Estimating a Tree’s Age by Counting Growth Rings
Growth rings refer to natural markings on the tree trunk indicating its age. You can tell a tree’s age by counting the number of rings.
The number of rings varies based on the species of tree and location, so you need to understand your tree. Counting the rings proves easy because trees often grow new tissue every year.
Light-colored and broader ring tissues grow in the spring and early summer. On the other hand, the dark, narrower tissues grow in the late summer and fall due to fewer nutrients and insufficient sunlight.
You can tell the tree’s age by counting the dark rings. This technique works well for dead trees, but experts use increment borers to date living trees.
These tools take a core sample to the tree’s pith, allowing you to count the rings without damaging the tree permanently. However, you must seal the hole to avert infection.
Calculating a Tree’s Age Using Mitchell’s Rule
Mitchell’s rule helps you determine your tree’s age by assuming its girth expands by roughly 2.5 cm annually. You simply need to measure your tree’s circumference and divide by 2.5 to determine the age.
How To Tell the Age of a Tree Using a Tape Measure
You can estimate a tree’s age when you know the tree species and the circumference. For this to work, you’ll also need a chart of tree growth factors. Follow these steps:
- Determine your tree species
- Measure the tree’s circumference in inches with a tape measure wrapped around the tree trunk
- Divide the circumference by 3.14 to get the diameter of the tree
- Multiply the tree’s growth factor by the diameter to determine its age
For example, a pine tree’s growth factor is 5.0. So, if your tree’s diameter measures 8 inches, its age would be about 40 years. You can find the tree growth factors chart online.
