Before beginning such a worthwhile project you should visit the local county extension agent to get an assessment of the soil and habitat information of your particular area. The size of the plot can be as small as a few feet or pasture size. Many plots are suggested plantings according to 1000 square feet. This size can be managed easily by planting annuals either yearly or seasonally. Many food plots are planted in small sizes but spread over a large range of acreage.
All wildlife have territorial ranges which can extend for a couple of miles to hundreds of acres.
Providing several plots enhances the chance of spotting the elusive animal that you might never see otherwise. Adding perennial food and shelter will keep the wildlife in the vicinity a lot longer than just making one stand of a crop that is only there for a few weeks. Perennials are plants that live for two or more years. These can be permanent grasses, trees, hedges, wildflowers, berry bushes, weeds, clovers, etc. Weeds may sound a little peculiar but they produce seeds and attract insects for such species as quail, turkey, grouse and many more.
