I let my plots of wheat and rye feed 'em until it dies late spring. Then the corn feeders go back out. I believe the feeders gets the deer in a routine of coming thru the place and without it they may not. Besides, with feeders out I leave cameras out and watch the bucks grow horns throughout the summer and then I know what's in my hunting area before the season opens again next year. My feeders only use a 5 gallon bucket of corn every 2-3 weeks and that doesn't cost much. Since I don't have to pay for where I hunt I don't mind buying corn.
