Manhattan with no airconditioning ? OUCH ! Been there done that ! Don't wish to repeat it ....
I tried 3x to grow this Angraecum, and was totally unsuccessful. I realize now that I should have summered it outdoors from Spring thru Fall. Right now I have a Brassavola nodosa blooming its head off the 2nd year in a row because I summer it outdoors.
I've just failed miserably with Angraecum, even though I love them all - they will not bloom for me indoors....
