I saw the subject line and worried about what I might find. Then I saw
who it was from, so.....

Ok, so how does one go about the spag'n'bag method of orchid rescue? When
does one do it? And what is it likely to accomplish?

It's been at least 20 years since I tried it. All it ever accomplished
for me was a rotted plant that died anyway. That's why I haven't tried
it in 20 years. That's also why I'll let someone else tell you how to do
it. Obviously I wasn't very good at it.
If it was my plant, I think I would take it out of the pot again. Trim
off anything that is dead, above or below ground level. Consider using a
smaller pot since it is now a smaller plant. Plant it deep enough that
the new roots have something to grow into. If it is trying at all to
grow new roots you might also consider semi-hydro. I never actually grew
a Phal that way but I have rescued other plants that were having trouble
keeping their roots alive.
Others will reply and will probably have better advice.
