It's impossible to come up with a precise age for a giant saguaro cactus [Carnegiea gigantea]. In fact, guesstimating ages just can't be done regarding any type of cactus. So much depends upon the individual cactus and upon environmental conditions. But a saguaro cactus that has at least one branching arm and that flowers, fruits, and seeds is at least 40 years old. Not one of the preceding activities takes place for a saguaro before that age. Additionally, it tends to reach its mature height of 40 feet/12 meters in around 60 years.
There's no certain way to tell a cactus plant's age. The age can be guesstimated based on known facts about the cactus, its environmental context, and its genetic inheritance. For example, a living rock or fossil cactus [Ariocarpus trigonus] measures 10 inches/25 centimeters in diameter once it's 100 years old. In the way of another example, the agave cactus [Leuchtenbergia principis] sports yellow, funnel shaped flowers and gren fruits once it's eight years old. In the way of still another example, the pincushioin cactus [Mammillaria sempervivi] forms baby offsets when it's 20-30 years old.
it depends how pointy the spikes are if its old and you touch it you will start to bleed if it is young you wont
A saguaro grows about 1/4" per year. By measuring the height of a saguaro one can calculate the approximate age of the plant.
In a way, A saguaro is usually at least 40 years old before it starts sprouting arms.

whack it in the face with a cactus
how long can a Christmas cactus live. our is 58 years old
There is no way to tell the exact age of a cactus. Unlike trees you can count rings, but for cacti some believe like the saguaro cactus you can use the arms to tell the age, but in the life span of a saguaro it can grow at different rates. if you have to estimate a saguaro it takes the base an average of about 60 years to grow to the size of a male adult.
100 years old

No, it may take over 100 years for the cactus to sprout its first arms.
The size of a cactus depends upon the type. For example, some cactus plants are naturally taller, such as the 40 foot/12 meter giant saguaro cactus [Carnegiea gigantea] and the 50 foot/15 meter old man cactus [Cephalocereus senilis]. And some cactus plants are naturally smaller, such as the 2 inch/5 centimeter living rock or fossil cactus [Ariocarpus fissuratus] and sea urchin or silver dollar cactus [Astrophytum asterias]. The size also depends upon environmental conditions. For example, cactus plants may not do as well outside their native habitat despite vigilant care. The normally towering old man cactus in the wild tends to grow no taller than 3 feet/90 centimeters in cultivation.
