I feed year round, more from Sept till Jan then less till Sept. I put out a lot with a road feeder starting Sept 1st. Feed each location everyday I can. Then when I hunt just feed that stand. Works great for me.
Personal property and lease I feed year round and step it up just before season. I have a few places that I hunt only during deer season (my daughters hunt them the most) I just started them up at the end of August and will feed till the kiddos get their deer.

We try to fill year round. For the past couple years hogs have overrun us so we keep protein 10 months of the year and corn during the season. We are slowly getting our feeders penned and will resume year round corn.
