Ok, i'll save people my background but my mom is an expert horticulturist as well. So over lunch today , i threw this topic at her. She reacted the same way as i did. The only plants that will consistently grow in shady areas are weeds and a small select few plants that are shady tolerant. Your best bet is to open up the area to get more sunlight. Sure you can the rye's , the rapes, the clovers and other food plot products to grow but it's rolling the dice. When people ask me this at seminars or shows, i can't honestly tell anyone of anything that will do great under those conditions. Anyone who sells products that says so, if a product seller and not certified crop advisor, agronomist, horticulturist or someone trying to give you sound advice.
If your going to plant anything, plant cheap...plant rape....plant some white clover, hope for rain...hope your pH is good....hit anything growing up with plant foods.....and PRAY
