Chances of recovery after advanced rot?

    After I moved, both my orchids caught black rot. I am not an experienced orchid mom so I did what an internet search advised and carefully cut out the rotted sections with a sterile implement, then applied cinnamon. The rot hadn't returned but my poor plants are still declining rapidly. Their leaves have started to turn yellow and look like they're getting ready to drop off. However, the root systems of both plants look relatively healthy. There are some pictures linked at the bottom.

    The first one (the one with only one yellowed leaf left) the rot was well advanced into the crown. I knew there wasn't a good chance of survival but wanted to try anyway. I cut out what I could. I understand that without any healthy leaves left, she can't make new leaves, but may be able to produce a baby orchid. Any way to encourage this?

    The second one (the larger plant) the rot affected a tiny part of the crown but not all of it. I cut that out, again with sterile implements and following with cinnamon. She seemed to be doing better for a little bit but now seems to be doing poorly.

    I water once a week and let the plants drain. I have not been using any fertilizer.

    From what I've read it's hard for plants to recover from rot if it gets far enough. A lot of the advice I've seen says to just get rid of the affected plants and start fresh. But I like these plants both were gifts from people I love dearly.

    Any and all advice is tremendously appreciated. I don't expect to save my babies but I want to give them the best chance.

    I'm sorry to say that in the shape they're in, I'd say they are "goners".

    For future reference, "Garden Solution", a product made by Concentric Ag, is a probiotic that populates the plant and potting medium with live beneficial bacteria and fungi, will virtually eliminate any rot from starting, and if you treat a plant that already has begun to rot, will usually stop it from progressing.

    Ouch, they don't look promising. I have a species Phal. that put on a new growth and survived after the top rotted but, I have to agree with Ray and say they are beyond recovery. Sorry.

    I was afraid you guys would say that. Well, it's what I was expecting ☹️

    Thank you for the recommendations, I will definitely remember them for next time.
