This question is for me and gardenvt.
Please take a look at the four celery plants in the first picture (above the marigolds). The ones on the left look good, but the ones on the right don't (closer picture of just 2 plants below that). Although, scroll down to the 3rd pic, and you will see a close up of the actual celery part, and it looks okay. At first, I thought it was lack of water, but that's not it. They have been like this for a couple of weeks now. They are growing, but the leaves just don't look good, but the celery underneath look okay. Should I spray it with something? Does it mean the celery is actually bad? What do I do about it?
Also, even though the celery isn't full grown yet, can I cut off one of the stalks to use it right now for my potato salad? Or should I wait?
