Don't mention it! It gave me the headache for a whole year and still don't know what's happened or why. I'm still guessing. After the blooming period is over, I'd like to move her in another room to get used to the light conditions till the next blooming. It's a bit risky but it should work as orchids are moved from greenhouse to supermarkets and then to different homes and still survive. Maybe I'm not lucky and I was given a fussy one 😁🤔

Orchids do love sun. At least mine. I tend to move them from the direct sunlight (as recommended) but they disagree. 🙂
However, I thing I found the perfect spot for them (they keep blooming since I moved them): a window sill where the sunlight is filtered by the trees. Sunny and warm during the cold seasons, shady and cool during summer.
Maybe yours needs a pot change? Or some fertiliser?
