RE: What trees or bushes....
How about Autumn Olive. Its a fast growing bush, produces berries that cling into fall. The Critters love them. I planted a few on my property last yr. Just seedlings, and are growing great. I've also recently planted Paw-paw, winterberry, and American bittersweet. I did research on each to see what conditions best suited them in my area. Plus all produce berries that cling into winter. I figure if your going to plant anything mights well besomething thats going to have produce in fall, and winter months. Thats when you want your deer to use it most. I also have several varieties of apples planted. All which hold fruit into mid-late fall. Like Granny Smith, Northern Spy. Crab apple is good also. Another often over looked tree is Hawthorne. It produces little red berries that cling into late fall. I've watched deer push their noses into the leaves to eat the fallen berries.Oh, and another tree I've witnessed deer devouring the berries in fall. Mountain Ash, it produces those clumps of orange berries. I planted few those too.
