How can I effectively compost black walnut leaves to enrich my garden soil?

To effectively compost black walnut leaves for your garden soil, shred the leaves into small pieces to speed up decomposition, mix them with other organic materials like grass clippings and kitchen scraps, and turn the compost pile regularly to aerate it. Avoid using the compost on plants sensitive to juglone, a chemical in black walnut leaves that can be harmful to certain plants.
