let me just add some info to the extent of the little prep work.
i would cut some small trees down and any little growth on the ground i would cut down to the ground as well and try to clear the ground up as much as i can, if there is stuff growing in that spot to begin with it tells me there is enough light to support the growth of a plot. i also would try and open the canapy up to let in some more light during the summer months. i would rake or blow off all the leaves and i would hand till the grounf with a hard rake, PH Fert and then seed. usually try and plan it a day or 2 before some rain. i mean i dont do my plots like that anymore i put alot more into them but for the guy looking for a lil hidy hole plots with minimal work those blends worked for me. And dont hesitate to try it on ground that is not easy to till and seems kind of hard. i tried it wih a hard rake, the ground was really hard but when those seeds pop the root system can find its way through hard soil better then your hard rake.... im not saying you will have the best food plot around but if you looking to get in there quietly or its a hard spot get some equipment there or eve n just making those little destination food plots closer to a bedding are perhaps, it works great...
