Glad to read that the Vanda is turning the corner. Some orchids can take a lot of stress and still bounce back. I am nursing a Ren. bella that is literally a stalk with two leaves and a root tip about 3 mm just peeking out. Normally I would trash a plant that bad, but these are really hard to find unless you go to a big show and preorder.
If I find one at Tamiami in January, I will probably trash this one. In the meantime, I am trying to get it to come around. Now that I see root action, I am going to put some rooting hormone on it to see if it will grow a little faster.
