Big farms around here have went as far as planting winter wheat for a spring crop, once the wheat is harvested planting their soybeans in the left over 8 - 10" wheat stubble, the thinking is the young plant has a chance to mature because the deer cant reach the small plants because the hard wheat stubble sticks them In the nose, at least once it reach's the top of the stubble, it has a chance to make it.
Anybody having trouble with deer and want to go through the trouble, get you some coyote urine, tie a rag to the top of a tee post drive it in the middle of the garden, load the rag up with said urine, re-fresh once a week. worked like a charm on my place. haven't see a track since I started this.
Cant help you with coons, haven't had to deal with those varmints yet but its coming when I get the chicken coop done I'm sure.
