I had a very similar situation to one described by Andrea at the beginning. I'm glad to know that my orchid is happy
Still, I'm quite concerned about it as recently its bottom leaves become soft and are loosing their turgor. I had this plant for more than a year and nothing has changed in the way I care about it. It stands at the south window and is soaked in the warm water once a week.
I would really appreciate any suggestions at what may be wrong with it.
