When you water an orchid you want to let the water run through the plant for a minute or so. Don't use cold water as this will shock the plant. Take your orchid to the sink and let tepid water or room temperature water run through the pot to soak the plant thoroughly. Be sure to let the plant drain completely. If water remains in the crown of Phalaenopsis plants (where the leaves join in the center), it can provide a perfect environment for fungus or bacteria to do their dirty work. Use a paper towel to blot the water to avoid crown rot.

*crown rot is your title so I assumed you wanted to address this issue.

the factors of potting at an angle or choice of media mix is of little importance as to following the correct watering method to avoid crown rot.... other members pot upright and they use different kinds of mix....yet they can grow Phals well....

the bottom most crown=last two leaves meeting at the very bottom of the plant is what you mean...then it is the 'basal crown' ...if you have more than 10 leaves then there will be more than 5 crowns....
*its just a matter of looking at the RHS illustration of the parts of a Phaleanopsis (it can also be found in a bound book made of paper without batteries)....

I was doing that but started soaking the pot for a few minutes instead because the bark is relatively new. (bark was presoaked before repotting was done)

I decided to ask regardless since it is well known that growing conditions result in changes that must be made to potting medium/watering schedule etc.

"it can also be found in a bound book made of paper without batteries" You can ask me to look at a illustration of a phal without adding this on to the post. It sounds offensive with the second part you added.

Sometimes there is water trapped where the leaf attaches to the stem of the plant. Sometimes this can lead to stem rot which is the same as crown rot. Instead of bacteria killed the crown, the bacteria starts at the bottom and goes to the crown.

If you put alcohol or peroxide on the dark spot you should be fine.

Yes they were the bottom leaves.

It would make sense that water was trapped because the method I was using to water recently was to dunk the pot and soak for a few min.

I put listerine and cinnamon because I ran out of H2O2.

Thanks

The base of the Phal should not be buried in any material whatsoever. If you buried any part of the base of this orchid in whatever potting media you're using, it has the potential to lead to rot.
Got it, okay. I did leave a space below the base so there is nothing around it. Hopefully this resolves the issues I've been having.

It is a bit misleading though since the plant was already potted this way and every video showing repotting has phals this way too.

Thanks again
