Do multiple arms mean anything on the Saguaro cactus?

Yes, multiple arms on a Saguaro cactus signify maturity and health. While they can start growing arms at around 50-70 years of age, the number of arms can also be influenced by environmental factors, such as water availability and sunlight. Generally, more arms can indicate a longer life and better growing conditions, as it takes significant energy for the cactus to develop them. However, each individual cactus can have a unique growth pattern.
