This eastern native ideally wants organically rich, well-drained soils but you will find it doing well elsewhere. Plant it where it will stay since it has a deep taproot and is difficult to transplant. The long pinnate leaves make a lush crown, are very pungent, and turn yellow in fall. Black walnut roots produce chemicals which are very toxic to certain other plants. Lists are available online of plants that will or won't grow well under Walnuts. Although young trees will sometimes begin producing nuts when only 4 – 6 years old, it usually takes 20 years before a tree will produce a large crop. 75 – 100' T & W.
