Orchid Update
Since my last post, I have noticed differences between my 3 locations. The bathroom appears unsuitable for orchids. I think that there is not sufficient light from the window. The desk is the second best location. Orchids are growing roots and leaves- and those in bloom stay in bloom. Downstairs in the kitchen seems like the best location. Growth seems more vigorous in the orchids down there. The purple orchid grew a new flower stalk!
I have relocated all the non blooming orchids to the kitchen window and the blooming orchids to the desk.
