You are in zone 6? Where is that?

This is not the best time of year to revive growth. Phals are through growing and would be starting to make spikes. I'm speaking from someone who tried this in NY many times. Just bad timing season-wise.

Spring is the time to try this. Daylight getting longer, temps warmer. But...

if you want to give it a go this is what might work.

Pot the plants in a mix of small bark with some sphag mixed in. Soak the bark and sphag so it holds water. Pot the plants carefully without damaging the roots which are still alive. Put in a bright place. The leaves which are left will help spur root growth. Keep the plants warm. Do not expose them to temps under 70F. If you have a small warm room, put them in there with a floor lamp or clamp type light with a CFL bulb.

If you have a bright, warm room put them there. What you are trying to do is keep the temperatures warm, the room bright. Only water when the bark looks dry. Sometimes the clear pots are good because you can watch for root growth.

Don't worry about the leaves. They look like they will die off but will continue to function until the plant decides to drop them. You need roots to grow.

Warmth, light and easy watering is your best shot. Come Spring, if they make it, they will make new leaves. I've had some survive and turn out to be beautiful plants. Others, made keikis (baby plants) while the main plant died. Some did not make it at all and died. You won't know until you try.

Good luck and let us know how they do.

Wow, quite a challenge. I know nothing that will make the recovery/re-growth proceed quickly. Perhaps someone more experienced with phals will know of something useful.

If I felt I HAD to make an attempt, I'd soak the plants for 30 min. In a weak rooting solution. Drain the plants, let dry for about another 30 min. With a sharp sterile knife or pruning instrument remove everything that is badly damaged/dead. I'd LIGHTLY dust cuts on leaves with cinnamon, DIP cut roots in peroxide. I'd take what was left of the plants, put them in one small clay orchid pot, tuck some damp sphagnum moss around remaining roots and put pot in a totally shaded area.

now if my husband saw me doing this he'd tell me to "put those plants out of their misery and bury them in the mulch pile!" And his advice would probably be the best.

good luck!

I have brought back phals in this shape. Sphagnum moss in a tiny vented pot, daily attention for months to keep it "damp but not wet" until a sturdier root system developed, and years before the new heathy leaves outgrew the old damaged leaves. Still, three years after taking on a case similar to your #1, I'm currently enjoying this result:

Do you have three years worth of patience?
