Q.What Should I Do For My Giant Saguaro Cactus That Is 15 Years Old And About Three Feet High?
I bought seeds in Sedona Arizona 15 years ago and planted them. They looked like little pieces of pepper. From this picture, does it look like I am growing it correctly? I kind of expected it to grow up having the arms instead of all of these other Main stems. Any advice?

It can take 75 years to get those arms, 60 in your case. It looks good though. Likely these are all individual plants. You may want to separate out a couple of them and put them in separate containers.
