Lindsey, sure hope your Vanda recovers. Keep us posted (when you get home, of course)
I just had to be-head my big Angreacum after it started losing leaves just like yours did. I had ignored it too long, as the rot started while we were away in Gr. Cayman. The whole top just flopped a couple of days ago.
Happy news is it has a couple of keikis that seem to be doing all right.
