Age of Bonsai

Hello! I am trying to find out what the age of my Ficus microcarpa Bonsai is. I have checked multiple websites that say that I have to use the growth factor but I do not know where to find it.

I don't know what the reference to growth factor means either! The most reliable way to figure out the age of a tree is to use the growth rings, but that would ruin the tree!

Every year, plants put out new growth, so that is another (less reliable) way to guess the age. However, with bonsai, quite often, entire branches could get pruned away.

This article has some information on growth size, which might help. Otherwise, it's pretty much a guessing game.
