Mystic brings up a good point here. Fertilize what you already have. Pick out a few white oaks and fertilize them, the acorn mast will be larger (more) and supposedly taste better (never tried one though). The deer will find these trees, and you can hunt them.You can also use natural stuff, like honeysuckel, grass, brows. also do a soil sample. If you have acorn trees ( there are differents one, this goes for all of them ) put in tree food spiks, throw in some wild flowers. there is more to a food plot then what the componyies have to sell.
