Phals seem to do better inside the house. Raise the humidity with a
tray beneath the plant or grow in a bathroom.

Crown rot is a major problem in a greenhouse. After experimenting with
phals in my greenhouse for some years, I have found a low-light (phals
were getting too much sunlight from the sides) on the greenhouse floor.
Phals seem to be doing well.

I'd only add to be careful not to mist too late in the day. You want the
leaves and especially the crown where the new leaves come put to be
completely dry before it starts cooling down in the evening otherwise you
risk crown rot.

I do agree that I think the problem is low humidity w/ unhappy roots.

That's why I was watering more frequently. I'll take the plant out of the
pot and check out the roots.

BTW, to help the plant recover, do you think I should cut the existing
flower spike off? I wonder whether the plant is trying to put our more
energy to flower than it can really handle with it's compromised root
system.

My guess is too much water (=dead roots) and not enough humidity + dead
roots is causing the shriveling.

Allan -
If the house is dry, mist the plant. Watering causes the mix to
hold water and can cause the roots to rot. If your leaves are
wilting, sacrifice today's flowers for tomorrow's. Cut the
spike. Cut the daily water back to 1-2 times a week, dry is
better than wet mix.
If it is terribly dry in the area:
Put in a humidifier.
Mist every time you enter the room.
Put a large collection of plants together in one location of
the room.
Put an aquarium air stone in a pot of water and pump air thru
it to create a mist effect.
Put a plastic bag over the plant to keep the humidity up around
it.
Any or all of the above will help raise humidity. The higher the
humidity the less water the plant will loose to the dry air and
the less the roots have to provide to the plant.

When you water make sure the surface roots, those out in the air,
turn green. If they are still silver and your done watering, you
have not applied enough water in the proper locations.
