Feeding Station and Heavy Rainfall

Hi Brian,
In your video you mentioned making sure that the bedding wasn’t too moist in the trays. I am thinking about using a feeding station in my veggie garden rather than the trays and I am wondering what happens to the worms when rain is torrential? During winter in SA it is typically very wet and cold and can rain constantly for a week at a time, are the worms going to survive in the garden where they can’t escape the water? Would I be better off using a tray form or worm farm?
Thanks so much
