Questions about damage from the cold....

[seabead22]

I think my orchids spent one too many nights outside when I was out of town in February. Here are my questions:

1) does cold damage show up in the the form of black leaves.....

2) if so, should i cut the leaves where they are black or does it not matter with cold damage aside from astectics

3) if black is not from cold....any other thoughts. All of the plants were fine before I left and its only after the cold that they are going ugly which is why i suspect that is the cause.

Thanks in advance!!

Also, by black leaf I mean one solid blackness, not spots like with some other causes.

AND I also suspect cold damage because the more temp sensitive ones like my phals have completely bit the dust. I am mostly concerned with my cattleyas.
