I have a cactus that I have grown since it was tiny in 1990. It is about eight feet tall now but never got any bigger around than its original two inch diameter. picture attached.
I moved it from my office to my house in Tacoma Washington last year with much concerted effort and it didn’t break! But I have to move it again soon. Oddly, for the first time in these 19 years, a little baby cactus sprouted on it about two feet from the top. It has grown to about 6 inches. The cactus part above the new growth isn’t looking very good, as if the new little arm is taking out the nutrients. I am afraid the old cactus won’t survive another move. If not, can I break the new arm off and grow it?
You can certainly carefully cut off the new branch. I recommend spraying the cut end with hydrogen peroxide to help it heal. Let it callous over for 1 to 2 weeks, and then plant in fresh, new, dry cactus soil. Don’t water for 2 more weeks.
In general, I would recommend not doing this ’til spring, but if you are moving it soon, you might as well try now.
In addition, it looks like the original plant is under-potted (I think, looking at the photo), and not getting enough light, which is why it never got any bigger around.
Good luck, and send us a picture of the baby in it’s new pot.
