I have quite a collection of these frost blankets now. I usually use them for spring freezes, but this winter I used them to cover some delicate plants when temperatures hit zero for several nights in mid January. Pictured is my eight foot camellia which I nearly lost during the crazy Christmas freeze last year. It’s still pretty pitiful so I knew I had no room for error. I rigged a framework of moving blankets draped along the bottom on electric fence posts and wrapped it up with one of the big plankets. Underneath I had it strung with incandescent Christmas lights and an electric dog water bowl for heat and kept it sealed for nearly a week. To be honest, I didn’t have a lot of hope, but I’ll even have some blooms in a couple of weeks! The second pic is one month later. The plankets do tear a bit around the eyelets and the tiny stakes are worthless. Plastic electric fence posts (which have hooks) and office binder clips really help on taller shrubs. My six foot indica hybrid azaleas are still bright green thanks to these things!Update:I attached a pic of my tender indica azaleas which are now in full bloom. I had them strung with Christmas lights and covered with plankets for a week during the winter when it hit zero. I lost the bloom on all of my other hardier azaleas this year but these look great.
