Hi all,

The cold may be the biggest problem I currently face here in New Jersey, where I keep my greenhouse at about 60 degrees. Surprisingly, my phals, which I think generally require warmer temperatures than other orchids, are thriving. The rest of my orchids are not. My dendrobiums have leaves which look fine on the tops, but the backs are a milky, mottled white, with some brown spots. Can anyone help diagnose?

Not to ask for too much here, but also my one Vanda has these brown diamond shaped spots on the leaves. I bought the Vanda in Florida, where I wish I were living right now, last spring and it has yet to bloom.

Thanks for any help you can give me.
