I think my plant is dying and I don’t know how to save it.
I bought this cactus a few weeks ago because I found it at the store without a pot just on the floor. I’ve never had a cactus at all, it was a in the moment decision to get him. I bought the right soil, and the pot had a drainage hole. I water him very rarely. He has been under my grow light everyday 12hr
I noticed that the red thing fell over, I started looking into it and I think it might be rotting. I saw somewhere that the green part could be saved, but I’ve noticed that some of it is going soft as well (my finger and up is all soft). Is there anyway to save part of the green, and would it grow more if I got rid of the rotting part.
I really would like to save this guy if at all possible.
Edit: I ended up cutting off all the rotting part so hopefully he will just regrow the green bit.
