Vegetables That Tolerate Black Walnut
My neighbor's black walnut tree has made my vegetable gardening difficult. Are there any vegetables which can tolerate their toxin?

Hello and thanks for this question. When I lived out on the farm we had several Black Walnut trees that presented me with such a challenge. I found that I could grow corn, squash, melons and carrots okay. Also lima beans, snap beans and some onions will tolerate the juglone in the soils according to some university testing. There can also be a problem with the juglone being abosorbed into the veggies that can cause allergic reactions, so be careful when eating the veggies that are produced in soils within range of the black walnut trees root systems.
