I find it always best when thinking about what to do with land, plan for next year.

Since its too late to do anything this year you are essentially planning for 2 years from now. What I would suggest and what I have had success with is planting food plots. Like the others have said, sometimes deer won't hit it the first year you have it out. If you have lots of healthy does in the area, you will have good bucks there.

Im not sure about the way the property is set up, but what I would try to do if I were you would be to set the food plot up where you can be in the woods 50+ yards near that natural funnel you talked about. Reason being, the deer will be naturally funneled to the plot and we all know that big bucks will usually wait till after dark before entering open fields. Setting up inside the timber like that allows you to have a chance at them before shooting time ends.

Definatly do not cut the grass!

So imo, definatly get a good food plot up or 3, set up in the timber where the deer will be funneled by you on the way to the food plot and far enough in where you'll have a chance at the big bucks and don't cut the grass.
