Hello gardeners!
First, thank you for letting to register to your forums, I am a new member.
(and relatively new gardener for that matter)

I have a ~4 yr old SanPedro Cactus, (trichocereus, I believe)
and the other day I noticed a peculiar growth on the side of my cactus.

I don't know whether this is a new little offshoot, or maybe something more sinister that should be removed.
if it were a natural offshoot, it seems odd to be that it would grow downward, but what do I know.

Attached are two pictures.

Thankyou! any advice is appreciated!

I use to grow San Pedro cactus when I lived in Arizona. When that cactus gets tall it starts growing arms. I never lot my cactus get tall enough to grow arms when my 50 plants were 6 ft tall I cut them all into 8" long pieces and sold them all on Ebay. I don't know how tall they grow before the plant grows arms. My cactus grew new plants out of the soil around the existing plants. 1 plant turns into 2 or 3 more plants then a year later those plants turn into 10 to 12 more plants. Keep an eye on that spot see what happens it might turn into an arm.

This is some of my San Pedro when I first started growing it.
