I am wondering about protecting my container plants, dahlias, bay trees, petunias, dianthus, etc, from frost over the winter. I have a large covered area that I could put them in but I am not sure if this would entirely protect them. Should I buy one of those plastic/temporary greenhouses and put them in this instead?
