Frost warning for tonight prompted the first frost protection of the year. We covered our celery because it is the most frost sensitive thing we have in the ground that we could reasonably cover. The tomatoes are staked and not really cover-able, and the peppers can actually live through a couple light frosts, which is all we are expecting if we get any frost at all. The celery, however, starts having trouble at 36 degrees.
This year we bought Agribon row cover as opposed to reusing some generic row cover we have used before. Let me tell you, the diffrence is amazing. The stuff went on easily and was not to flimsy. I have confidence that my celery will be with us anouther couple weeks!
