|Mine grow about 1-2 feet a year (zone 9b). They also sprout arms anywhere from the base to near the top. Because they can quickly spread out with those arms, I keep mine trimmed, and don't allow them to grow higher than 7 feet. Whenever a piece is cut back it quickly heals over and most often will generate new, smaller diameter arm buds at the cut end (see the top of cacti in picture). The root system is not very massive, so the cacti do well in general garden areas, and can do well even in pots. I have raised a couple of arms in pots and not only have they thrived over four years without root-trimming, but last summer one of them even flowered.

|Very nice Chalyse! I've been in this house 1 1/2 years now and I don't know how long mine has been in the ground but it hasn't grown very much at all. I'm just now noticing small "nubs" on one side that are just jutting out a bit ... don't know if that will be "arms" because it doesn't appear that this plant has ever been cut back. It's only about 7 feet in height and seems to be a very slow grower. I've been thinking of chopping the top off and letting it callous over and planting it but never seem to find the time.
