We have plenty of redwoods growing in my country (NZ) that aren't watered by fogs but by just plain ol' rain.

While I'm sure that fogs are essential for redwoods in the California climate, it doesn't mean they are inherently coupled - they grow quite happily in the inland Canterbury Plains, bugger all fog, but enough rain to get them watered.

Hell, we even named a suburb after one: https://en.wikipedia.org/wiki/Redwood,_Christchurch

Fair enough, interesting fact just as all roosters are chickens but not all chickens are roosters, not all redwoods are sequoias. I actually mixed them up too.

Yep, I've seen both in our botanic gardens :)

That's in summer, they still get a lot of rainfall in winter. Even then not more than half their water in summer comes from fog
