Default help with a sick laelia gouldiana!

Sarah: In keeping with what others have said, I wouldn't be too concerned
about those 2 yellow old backbulbs -- unless they turned that way very
quickly? You have 3 nice-looking newer growths.

As a precaution, as well as a cosmetic measure, you might want to cut off
those 2 pbs and inspect the cross-section of the rhizome for fusarium. If
your cross-section is clear green, white or beige, all is good; if there's a
purple ring or purple blotches, that indicates infection. Kenni

Hello,

I purchased a beautiful, mounted, Laelia Gouldiana a few
months ago\. It was doing beautifully, and bloomed
just before thanksgiving. I took it back to pittsburgh (I live in NY)
with me for the holiday and shortly after I brought it back, the bloom
fell off (I imagine bc of the rapid temperature change).

Now, however, it looks like there is a problem with the pseudobulbs! 2
of the 4 (the two that do not have leaves growing from them) are
turning yellow/ orange and it looks like they are dying. the tips are
also developing a dry, crusty looking bits, and on one of them, it is
developing dry, crusty patches along it's surface. Any ideas??

Also, after the bloom is finished, do I cut it off? At what point? (the
stem is now brown as well... is that supposed to happen?

I have attached some pictures...

This is my first orchid, I really appreciate the help!

thanks
Sarah

Also, some of the orchid care resources say that Laelia Gouldianas do
best when they are watered less in the winter... is this the case? I
have also heard that it is virtually impossible to over water a mounted
plant... am I safer to err on the side of too much water in this case?
Should it be fertilized? If so, how often?
