They really can’t tolerate temps below 40F. I would consider covering them if you expect temps between 45F to 50F.
It is best to cover plants with a cloth sheet. Do not use plastic directly as this will harm the plants, though you can cover with a cloth sheet and then a plastic one if you are expecting rain.
