Orchid looks unhealthy
My orchid has one stem turned yellow and the flowers on it are dying, the other stems seem fine so far. The orchid was beside the TV, does it matter? I just moved the orchid closer to the window, what shall I do to save it?
It looks like the flower stalk has just finished blooming. This is normal. Cut it back to just above the bottom nodule. There may be another stalk from that area in the future, otherwise a new stalk will eventually be coming from the base of the plant.
