Hi Bilco178
I usually keep putting some food out for a while (at least a couple of weeks) after I have seen the last hog. Sometimes other hogs turn up or even hoglets, where other people have stopped feeding. Some people continue to leave a small amount of food out all winter in case. But some hogs (mostly hoglets) decide not to hibernate and if you have one of those visiting just keep providing food and water as normal for as long as it continues to visit
It’s a good idea to leave water available all day every day, including during the winter. Hogs sometimes come out of hibernation for brief periods during the winter and may welcome a drink.
