Introduction:
Do you want to know how to tell how old a saguaro cactus is? Saguaros are slow growing and can live up to 200 years, so it can be difficult to tell their exact age. But there are a few techniques you can use to estimate the age of a saguaro cactus.
How to Tell How Old a Saguaro Cactus Is
The most reliable way to tell how old a saguaro cactus is to count the number of arm segments it has. Saguaros typically begin to form arms at around 75 years of age, with each arm segment representing about 25 years of growth. However, some saguaros may have multiple arms, making it difficult to accurately estimate their age.
Another method of estimating the age of a saguaro is to measure its diameter. Saguaros usually grow up to a foot in diameter each year, so measuring the diameter of the cactus can give you an idea of how long it has been growing.
You can also look for signs of age in the saguaro’s trunk. Older saguaros tend to have thicker trunks and may have signs of weathering or damage from animals.
