Rust color on Vanda leaves.

Thank you Roberta. I forgot to mention that I do have a 70% black shade screen over the entire green house. At this time of the year, the green house gets a lot of shade from a large shade tree to its south. I think that I will experiment then and move plants around to a shadier part of the green house. In summer, the green house will get full sun. Thanks again.

The Phalaeonpsis will definitely benefit with more shade. The Vanda can take higher light - that "suntan point" of light is actually ideal to encourage blooming. (Dark green leaves may be attractive, but insufficient light - indicated by dark leaves - is the primary cause of non-blooming in an otherwise healthy orchid) With any orchid, higher light can be fine as long as it is increased gradually - it is sudden change that toasts leaves. I can't read the tag in your photo... what is that Vanda? (it's species or hybrid name can tell a lot about cold-tolerance and light requirement)

I trust that you can read the labels now. These are obviously very young. I am a newby and just getting started trying to do the right thing with the orchids. I moved my Phals to the shadier side of the green house. The vandas have a lot of discoloration on the leaves not light green that I see on internet photos. Thanks again.
