We Get Questions
Q: Hi,
Our cactus of 12 years is dying, I dont know the type of cactus so I have taken some pictures of it so you can help. I wanted to see if I could get your opinion before i started cutting it up it has grown to over 5′ and we would hate to cut it up if we dont have to.
All the best
David
A: David,
From your photos, it looks like your Euphorbia trigona it has a very bad sunburn. Did it recently get moved or turned so it faces a new direction? That is the usual cause of skin bleaching. If not then it most likely has a bad fungus infection and you can try curing it by spraying with a 1% Neem Oil solution. However the scar tissue will remain and will eventually turn to “bark”.
Sorry I can’t give you better news.
