There really is no way to start a food plot in a totally wooded area. You need an opening big enough to get at least six to eight hours of sunlight everyday for food plots to survive. That said, you can plant other things in a wooded area like honeysuckle and others that are shade tolerant.
If you have alot of agriculture around you you might want to make your land attractive by creating some thick area's where the deer can bed. If there is not a whole lot of agriculture it might be worth you while to create a opening around 150 ft by 75 ft or bigger and plant some clover. Making smaller plots you can use an ATV or even work the ground by hand with a tiller and rake.

Anytime you have smaller narrow plots that the deer feel secure in they will come out and feed at any time of the day. Alot of times these plots get used more in the daytime and more open area's ae used at night.
