Welcome to the OB Karen! I have learned so much being on the O Board. There are experts on everything here. There is a forum that fits almost any question you have about orchids. I only have one vanda. It is remarkably care free I think. I bought it in March and it has bloomed twice already. Mine likes humidity, distilled water and constant even moisture. There may be something in the water here some orchids don't care for. I know we have silica but other than that....
Have fun on here and share pictures of your 'chids.
