You should be fine!!!! So long as it doesn't hit freezing.. We were down to the low to mid 30's* with no cover ..I got no tip burn at all.. I did cover the Squash and Tomatoes tho!!
Don't panic.. If they are in pots and you feel the need to move them just put them by the house you should get some residual heat .. enough to keep ya safe..

Sorry for the late reply, but thanks. They did fine with no covering. It was like 37 for about 2 hours only. Hopefully I wont see any damage in the coming days.

Over the past 10 days we've had several nights with temps dipping into the upper 30's. It hasn't been damaging but it's certainly slowed down growth. For goodness sake it May already. We're not supposed to have temps in the 30's!!!!!!!
