My wife currently brought home a Cereus peruvianus monstrose (you will have to forgive me if I'm labeling things incorrectly. This is my first "rodeo" with cacti). While attempting to repot the rather large cactus (two long bodies/trunks, one approximately 1.5/2 feet and the other approximately 1/1.5 feet) the shorter trunk fell straight off the base of the cactus. I assumed it was simply the weight or mishandling. I attempted to read up on replanting the trunk that fell off (the shorter trunk), and many forums suggested letting the piece scab over before repotting.
That said, I was looking at the area that broke from the base of the cactus and noticed it seemed very odd (as in not bright green and fleshy). I don't know what cactus scabbing looks like, but I feel as though this is already scabbed. I thought maybe the person we bought it from already had this issue and perhaps there was some foul play?
Either way, I am uncertain as to 1., what scabbing should look like before repotting. 2., what to do with this severed trunk of the original cactus before repotting, 3., what steps I should begin taking now.
Thank everyone and anyone for any help.
