Ugh both. One new plant shoot was growing ok but when I checked today, saw black root rot at the base. I think there is bacteria which I can't get rid off in this plant. Will check again tomorrow.

This looks like black rot to me. If so, it must be dealt with like this: Since it is a BACTERIAL infection, cut into the green part of the healthy stem, in back of the rot.
This must be done with a sharp tool, which has been dipped in alcohol. Spray the cut with alcohol,then, powder the cut with sulphur. Re-pot into new media, and leave cut slightly above media, so that the cut can dry. I've done this a number of times, and it always works. Good luck...BettyE.

I ditto all of the above! And I still like flowers of sulpher as a bacteriacide too.

Do what Betty says.

When nasties invade, you have to hit them hard.
Nothing like listerline or other mild home remedy works.

Two things will save this cattleya. A lot less water and a good systemic fungicide. The charcoal it is planted in is very coarse which is good. But you keep it too wet. Hence the fungal/bacterial problems. Calcium will also help but less watering, to near bone dry is what will do the most good. The old pbulbs are nothing more than food storage at this point. It is the new growth that is important. Until that new growth gets roots of their own, it isn't necessary to water so much. The old pbulbs have enough energy to support the new growth so less water will help stop the rot. And a good strong anti fungal/bacterial will also help.

So smart, I ditto!

If it helps, I pot my large Catts in coarse tree fern! It almost never breaks down, affords exceptional air circulation at the roots, the roots seem to travel about among the "sticks".....but I first cut the tree fern "sticks" in half to make each stick shorter so that they may better fill the pot; I do this in big clumps of many, of course.

Using this medium makes it almost impossible to overwater.....and, it also shows you how little water most Catts need....tho they want to be fully drenched when we do water.

I say things like that make a nice splash when they hit the trash can ;)

Will have to try it this weekend, if the plant is still around! ANd agree, I don't think it is a normal over water situ...

Sad but true. I gave up. One NOID cattelya gone.
