How do you tell bamboo age?

To determine bamboo age, you can count the number of internodes (the segments between the nodes) on a culm (stem). Each internode generally represents one year of growth. Additionally, you can observe the thickness and color of the culms; younger bamboo tends to be thinner and lighter in color. Finally, the presence of new shoots emerging from the base can indicate the age of the plant, as they typically appear annually.
