I would have if any looked like they needed new water, but I don't remember any Brugs getting that way. I'm not against putting them in pots instead, but it didn't go well the winter I tried that. If you want to try the water thing, I recommend a big jug, 1/2 gallon, because they are so thirsty. I've used opaque milk jugs and some clear plastic juice jugs. They have bigger openings than something like a beer or wine bottle.
