In my experience celery seems to transplant very well. At the end of last summer, I dug up about 10 of my full sized celery plants from the field and moved them into my high tunnel for winter. They were all fine, none showed any signs of stress at all. I'd move them if you're concerned about spacing.

Agree, but I would not move them. You will just get slightly smaller stalks, that is all. I suggest you transplant them to soil in the fall. They will perennialize.

Thanks y'all - I have one more question. I have read to wrap the plant in cardboard two weeks before harvest to blanch the stalks. I know there will be less nutrients by blanching them, but they will be more tender. MY QUESTION - how do I know when is 2 weeks before harvest? Since this is my first time growing celery, I have no idea:)

Two weeks before first frost, give or take. In fact, it will take a light frost and get a bit sweeter, so you could decide to pick it one month after first frost, specially if you have an indian summer. Unblanched celery is so much more flavorful than blanched, I do not blanch.

Isn't unblanched celery tougher? That is the only reason I am thinking of blanching...They said in the article I read that if you don't blanch, it will be tough like the outer stalks of the celery you get in the grocery store.

The celery I grow in the garden from store bought stalks are far more, shall we say "strong" than the original stalks I buy in the store.

I use my garden celery in soups and stews. VERY tasty and STRONG tasting!

I haven't grown any celery that I've liked to eat right out of the garden, just in cooking. Nancy

Nancyjane- do you just plant the root end of store bought celery or how do you start them?
