I bought this orchid 3 years ago, when it was blooming beautifully. Pale green petals, and a deep pink centre. It bloomed for months, and when it finally quit, I waited patiently for it to bloom again. I watered it with a quarter cup of water once a week like the books said - but nothing. I moved it around the room to new locations it might like - nothing.
Then a maintenance man where I work bragged about his wife's reblooming orchids, and let me know the secret: Once a week, fill the entire pot with water, wait 20 minutes, and then take out the plant in its inner plastic pot and dump out all the water. I was willing to try anything.
Within 3 weeks, success!
Notice the difference between the air roots (pale green, blunt end) and the flower shoot (shiny dark green, with tiny buds at the end.)
I was pretty excited, but still looking for just the perfect location for the plant. It was close to a south-facing window, and the leaves burned. I moved it away from the window, but the leaves pointing away from the light curled up and the leaves facing the light stretched out. I took it home and put it in an east window - more burned leaves. I felt like a bad mother.
Then I found the right spot. With bright indirect light coming from two sides, under a thriving spider plant, atop a shelf that looks like a waiter's arm. Success!
