Need some help figuring out what’s going on with my Dragonfruit. A little under a year now, it’s been showing this hard, sometimes orangey substance. Over time, it hardens the ends but I’ve been noticing lately that some of the Dragonfruit is now rotting and getting soft and mushy. I’ve had this plant going on for almost 2 years now. It was growing really nicely and healthy up until maybe last summer when I noticed this. Have asked around and done some research but can’t really seem to pin down what it is. Have it on a fungicide treatment at the moment but hasn’t really done any progress and maybe made it worse. Really don’t want to have to get rid of it or throw it away, so appreciate any help
