It is so satisfying when you see your crops grow and ready to harvest! That's a great feeling.
I've never planted celery but my wife uses a lot in her kitchen, she's from Morocco! Usually when it's good price , we buy s good stock, chop them and freeze for future use!
I use celery in many of my soups. I made a beef soup yesterday with it and used it in a chow mein on Saturday. I've never tried freezing. I guess it's ok if you are going to cook with it.
Exactly you can freeze it in an air tight container or vacuum pack for use in soup! She uses it in her traditional Harrira soup!
