Hi Brenda and Ed... welcome to Orchidboard
Vandas need LOTS of water...especially here in Florida.
Sometimes one or two of my vandas decide to pout a bit and I try to move them into an area that has a bit less light. Sometimes it helps...but the two that are pouting out there right now still have an attitude!
We've got lots of great growers on OB and many of us have vandas so hopefully somebody else will chime in with some ideas
If you have any questions, please feel free to ask
