My first try to post from my phone.

I gave my daughter this Onc. SHarry Baby a couple of years ago. It lives in her bathroom in Salt Lake city which is the best spot we found for it. She now has a newborn and a toddler so no time.

The plant got severely dehydrated and I'm attempting to rehab it. I filled the glass vase to the necks of the pseudobulbs and let it soak an hour twice now.

Leaves are a good color but all the pseudobulbs are super wrinkled. Thoughts?

I have left my Wilsonara in water for 3 days before, and it did plump back. That is the Oncidium that taught me just how thirsty these Oncidiums go during our hot and dry summers. So I now give them lots of water, especially during summer when we get too hot and dry.

Going back to that Onc. Sharry Baby, I would still have kept it in its container with its media and drain holes and sink it in water like what you have there, leave it in water up to root zone for 2 to 3 days and remove the main container to allow them dry out time again. They love water but certainly good air circulation after a good dunking, and by then the media will still be wet, so roots still going to stay nicely moist, and not getting too disturbed as it gets water dunked.

It hasn't had a pot for 2 years, just sits on the pebbles in that glass vase, bare root. It had potting soil around it when we got it, and so I just rinsed that off, and put it in the vase with the pebbles instead. It's been happy like that for 2 years, and bloomed a couple of times too.

I'll keep flooding it and letting it soak for another day or two, hope those poor p-bulbs recover.

Most people I deal with simply cannot believe that orchids are tough as nails. How else can they sit, bare-root, on a shelf at Lowe's for four weeks, without a drop of water, and still be able to be "rescued". The Sharry Baby should respond . Just give her some time and TLC. Growing in a pebble-filed vase, huh?

Ah okay, then, good thing you removed the soil. Definitely not a terrestrial..it loves being moist, but loves the air circulation at the root zone.

In another orchid forum I go to, they often do semi-hydro, using a container with two holes about an inch or two from the bottom, so it acts as fill line overflow. The media they use is clay rocks. So they fill the container to the top with water, blocking the drain holes temporarily to allow the roots to soak, then removing block to let the water drain out, leaving a water reservoir below the drain holes line. Seems you are almost doing it in the current set-up. It would make draining out water faster.

This Sharry Baby has the nicest looking leaves! Most of the time they are spotted, not this one. And I don't see Accordeon leaves either. Surely it will be ok with a bit of soaking.

The air here (Salt Lake City, high desert) is horribly dry all year, and in summer they run a/c which dries things even more. So the vase/pebbles system was the way to keep some humidity around the plant.

I sure couldn't get away with it in Florida. Those leaf spotting fungi love the high humidity don't they! I'm guessing they just don't exist in the air here.
