Hi, I'm new to the forum. I hunt in Upper Michigan as my name shows and I am interested in planting a winter food plot in order to keep deer feeding on my property in the winter and give the deer needed food in the heart of the winter where there isn't much out to get at during these cold months. I currently manage 3 food plots that have a blend of seeds. However, as soon as the ground freezes, the deer seem to stop using the food plots. I also hunt in an area with very low soil ph level with mostly cedar and white pines. Any suggestions.
