I have a good spot that I have planted for several years with normal food plot products, I want to plant some corn and soybean this coming season. My question is how do I protect these crops until they mature for the deer to use this fall. I don't want to scare them off for good like some of the products state. I want the deer to use it but not until hunting time. Any ideas how to accomplish this would be greatly appreciated. I want them to only use it when I'm ready for them to use it.thanks.
