I have used oilseed radish in the past for a fall/winter cover crop and never got any takers. The deer did not even touch a turnip plot. However, I seeded some topsoil hills left from my partially complete latest pond project with oilseed radish and clover late summer and had deer digging through the snow to bite off the radish tops. I think that they needed to learn, or maybe they were desperate in the snow. They continued the grazing even after the snow was gone. We have a lot of browse like blackberry as well, which was available even in deep snow. I put out a mineral block, but no food other than the live plants. My goal is 2 does per buck, but would be thrilled to have a 1:1 ratio which leads to more trophy bucks. I have a lot of deer, and there are plenty of does, even with a large coyote population.
