The delicious Black Walnut nuts must be gathered early, before squirrels and other wildlife can consume them. Of all the native nut trees of North America, the Black Walnut is the most valuable. Some plants do not survive near mature trees due to juglone, a natural herbicide produced by the tree. An exception may be so that may be a good understory choice. Other plants that juglone doesn't affect are - Asparagus, Apples and Crab Apples, Cabbage, Osage Orange, Potato, Columbine, Peony, Rhubarb, Blueberry, Red choke berry, Cotoneaster, Hydrangea,Lilac, Viburnum spp., White birch, Hackberry,Larch, Linden, Silver Maple, Pine spp.,Spruce spp. Juglone is also bad for horses, so keep this in mind when planning
Black walnut is best grown in a moist, fertile, sunny site. The deep tap-root means you should plant it where it will stay. Walnut trees can bring big profits to the landowner and be a part of a profitable agro-forestry planting. see:Growing Walnut Trees For Profit
Plan on 4-7 years of growth before walnuts are produced from these plants.
