The only ones I covered were the new intros that were newly planted that more than likely had never seen one bit of cold since they came from down south. I covered them with big nursery pots mainly to keep the rain off of them which would freeze down in the fan. These look great, however, the ones that didn't get covered are catching up with them.
I've only lost a few of mine but if they would have been more established (I had not to long redid the beds) they probably would have made it.
