Cactus Age Determination
Name: Laura H.
How can a person tell the age of a cactus? Is it the amount of spines?
Some cacti are more spiny than others but that is more likely related to different species
and habitats. The age of a cactus is more likely related to its size. You can probably find
more info from writing to a desert garden.
