May 13th is not supposed to see frost! In fact, I had ordered some tomatoes and peppers from a company, and they won't ship until your frost free date..... Well they shipped mine yesterday. It was so close that I hope my plants are OK. I was supposed to cover them up yesterday, but we had a small family emergency, and it slipped my mind. Hopefully, everything will be A-OK.
Hope your plants are OK too..... What a crazy "spring".
