I hate to waste food and especially fresh produce. Here’s a great tip to avoid tossing out your limp, lifeless celery.
First cut off the bottoms of your celery stalks. Then put all of the celery stalks in a large container or pitcher of ice water. Let the celery sit in the water for a couple of hours or overnight in the refrigerator.
You will be amazed at how it firms up and how fresh it will taste.
I had some old celery that was very limp. Rather than throw it out, I cleaned it, put it in a plastic container with water and left it in the refrigerator. It crisped up but it also stayed crisp for more than two weeks.
