Juglans nigra (Black Walnut) is a massive, long-lived deciduous tree grown for shade, wildlife value, and its flavorful nuts. You will get the best growth in full sun and deep, well-drained soil with consistent moisture while the tree establishes.

Give it lots of space: a mature black walnut can become very large and wide, and it develops a deep taproot that makes transplanting difficult later. Plan for leaf and nut drop in fall; husks and sap can stain hard surfaces, so site it away from patios, driveways, and walkways if that matters to you.

Black walnut produces juglone, a natural chemical that can harm certain sensitive plants nearby. If you are planting around it, choose tolerant companions and keep the root zone mulched rather than crowded with delicate ornamentals. Once established, it can handle periods of drought and is adaptable to many soil types.
