Help save my Catteya from root rot

[Ruby_House]

Hi,

I got this orchid a few weeks ago but since it was flowering I didn't check the roots like a usually do when I get new plants. Today I couldn't take it anymore and unsurprisingly due to the old potting media it has root rot.

So, I took it out of its media and i think i found one root that looks okay... not great though.Since then, I've been looking up ways to bring it back from this and one method I read up on is the sphag. and bag method. I just want to make sure I'm doing the right thing for this orchid and not setting it back further...

The first thing I'm planning on doing is working out which roots are goners and which one i should keep on the plant and remove all the media still stuck to the plant.

After that I've seen people add a big of cinnamon to help with bacteria. Would that be a good idea? I've also heard of people using rooting hormone and honey but i"m not sure how they did it...

Next, I'm gonna probably have to cut the flower off due to the bag.

Then place the orchid in a plastic bag with some wet sphagnum moss in the corner, close the bag but still allow for some air to enter and place it somewhere where it still get light and some heat to induce growth..

So yeah I just want to know if this seems like a good plan and what your experiences with this method have been. If there's a different method that's worked for you with Cattleyas I'd love to hear it!

Thank you!
