I'm no vanda expert, but I'm told that you can make a top cutting below three good roots. Don't toss the "remains", as you may get keikis. If you don't have three good roots, try using Keiki Grow on the bare stem and bide your time.

There is a FaceBook group called Florida Orchid Growing. You must be a Florida resident to participate, and I see that you qualify. There are *many* vanda growers there, and any question you ask is answered immediately, if not sooner. Tell them to sign you up.
