Floating row covers for frost protection?
 

Garden floating row cover 25ft.Plant frost protection Agribon 19 | eBay

Want to get prepared: Even though I live in Southern California, but close to the beach with a canyon behind the house that sucks cold air in during the winter, I do get a few nights each winter with temperatures around the freezing point. Due to the frost my Plumeria has suffered bad frost damage as well as my "Angel's Trumpet Trees". The "Angel's Trumpet" trees usually recover fast and well every spring, the Plumeria struggles.
Next winter I want to avoid the frost damage and of course I do want to protect my banana plants as much as possible as well. So I wonder if anyone has used the Agribon 19 (see link above) floating row covers and does it work? It seems awfully thin to me. Do I have to wrap the plants in multiple layers to make it work? How would I use it on my so far 7' tall banana plants? Any other good ideas?

I have not used it but know many people who have. I actually bought a 6' x 1,000' roll of a competing brand for my tomato project but ended up delaying my planting until after frost was gone and never used it. A friend of mine near Fresno has used it for many years on her tomatoes and it has worked out well. I think for your light frosts you could just cover the tops and somehow clip the cloth onto the plat to keep it in place. That should be enough to trap in heat and protect your plants. Good luck!
