Well I been watching the weather and last few days was showing it be about 39F but it was about 45F, that was all good for me and my plants.. Well last night they started out saying 41, then 39, but it really got down to 26F plants frozen but I think covering up two of them,, might saved them so I can dig them out and re-pot them and get them into the little Greenhouse to over winter, Others I think some there's no chance.
