Barberry poor collection technique, now wilting

Here’s the barberry. It’s leaves are now wilting. If you look at the clay it was in, I obviously should have soaked it over a few days. It will be such a tough mistake to learn the hard way if it dies. I will learn from this either way. My question is:
Should I trash bag it to reduce transpiration? It’s in full shade & I’m not touching it for any reason.

Just keep it out of the sun And hope it survives
