Unfortunately I guess various species of these pathogens are adaptable enough, Elaine. The RHS has been doing some research on them:

In some parts of Florida I think it gets colder on occasion in winter than it does in at least parts of the UK? I grew up in southern England and the last place we lived was the equivalent of USDA Zone 9 as far as winter was concerned. Yes, very long days in the UK in summer (and very short ones in winter
)
