Unless you can regraft it on something else, then no.....

Normally Hylocereus trigonus stock are very durable, can with stand over watering.

A farm near my home, a sea of moon cactus.

I've seen a few with flowers in the store but never had them flower for me at home.

Repotting can't be as stressful as rotting. That plant has been rotting for a while. Rootstock is quite vigorous plant; and to get it so rotted happens when it is left sitting in wet soil. Usually, it could be saved by cutting off all rotted part and re-rooting the healthy piece. However, there is likely not enough of healthy tissue left.

Perhaps regrafting as Stefan suggested could work...

rina, when those things rot, the entire segment rots...i am talking out of experience..... dont know why, but its always the original stem, and perhaps the first offshoot produced by it. My plants have been stable since though...

I have seen them with glued on flowers in store - and a couple of pics online - never for real.

Not that it doesnt happen....youre just more likely to win the lottery.

on the latter, when a comment was made by spanishfly to quote:" try growing plastic plants" directed at me..

Thanks, I thought you were referring to info relevant to this thread.

"Abuse" may or may not exist here...I do not believe it does on this site. I remember Spanish Fly feeling the same when I first questioned some of his statements. I believe - actually I am quite sure - that he realized I was not abusing, just questioning him. That is the only way to get best info, and/or clear up misunderstandings. We all make mistakes, some often, some occasionally, in our posts. Correcting incorrect info shouldn't be taken as abuse...but I understand that written words do not show 'emotion' that well and are often misunderstood. Especially, if they are written by ppl that don't pussyfoot around in fear of hurting someone's feelings, and post just facts. Or if they joke and jokes are misunderstood (even if some 'jokes' may sound too personal or as attacks). I am member of this forum because I found it when looking for some help with plants - it was Ficus Benjamina, not a succulent - and I found big bunch of extremely helpful ppl here. So that's why I am here - get more info, learn as much as possible for me, improve my growing and help others if I can. Lots of very helpful information is readily available here, free, and often takes a while to post - taking that persons time.

This is JMO - not a criticism or abuse...

Im not upset....but id rather the other user to tone down the disagreement and the comments , even if by a notch. Im here to help as much as i can, and learn. Not to argue.
