I've never had any luck DE Rape. I could not find the thread where someone had good luck with canola. There is a big difference between DER and canola. Anyway I did a small test plot (July 1) in canola and GHR and it is being hammered. My deer are picky,but they love this. Thanks for the tip fellow member. Some seed places are not sure what they are selling. Some call all of it rape seed. Elk Mound seed is where I got mine and it's the real deal.
