The Black Walnut puts the substance Juglone into your soil which is poison to many plants. I am constantly killing those trees to keep them away from my garden. I have one near my blueberry plants which I will be cutting down very soon.
Black walnut shells can be used to dye fabrics a dark grey colour. Soak in water with the fabric. Set with vinegar.

Some of them are coming close to harvesting. Squirrels have been getting some of them.
So anyone have ideas for plants that would thrive underneath black walnut trees and not be affected by the juglone? Especially interested in edible perennials that would grow well underneath in partial to full sun underneath. Is an area that I want to make use of if possible.
