However, do not be deterred from having a garden under this tree! There are plants that are tolerant of the compound, including ferns, bee balm, and astilbe.
Once mature, the seed husks are used for natural dyeing.

Care
Water Black Walnut trees deeply and infrequently to promote profound root growth. Mulch near the bottom to maintain moisture and regulate soil temperature. Prune during dormancy to remove dead or crossing branches and prevent disease.

Plant Reproduction
Black Walnut spreads via fallen nuts and root sprouts.
Plant bare root trees during the dormant season in early spring or late fall (November through April). Dig the hole twice as wide as the roots so the soil is well-drained. Position the tree so the root flare is at or just above ground level. Fill the hole back with the soil you dug from and water. Maintain soil moisture, especially in the tree's early years, by providing deep, regular watering. Apply a 2-4 inch mulch away from the trunk at the base to retain moisture and suppress weeds. Prune trees during the first few seasons to establish strength and resilience, remove damaged branches, and continue maintenance pruning as the tree matures. Regularly inspect for pests and diseases and apply integrated pest management practices. Protect young trees from mechanical damage and extreme temperatures with tree guards, and stake them if necessary for support, removing the stakes after one or two years.
