Thank you, SouthPark for the photo! I'm happy that you save your orchid - it looks very good! I think my patches were a little different and l'm pretty sure that they were because of overwatering-I just didn't have to spray water on the roots the last time before my vacation...Anyway, now the plant is dormant, I don't see any black spots any more. Although the orchid doesn't look as pretty as before, I hope to save it. Thank you again and have a nice day!

Most welcome silanah. The colour of the patches (originally, when I first encountered the issue several months ago) - not shown in the photo that I took this morning - were exactly the same tones and colour as you showed in your original photo.

In the photo that I uploaded, the patches are now dried to a dark brown colour. The regions remain sunken-in a little bit, but totally dry and hardened up.

Nice to hear there are no more blackening regions with your bulb!
