The Q&A Archives: Plants That Cannot Grow Near Walnut Trees

Question: Our neighbors own two walnut trees and we have predictable trouble with juglone. Is there anything we can do to save our tomatoes and eggplants? We've also had trouble with okra, fennel, rhubarb, and asparagus. What can we plant that will grow? Please help, I'd hate to sell the house just to grow tomatoes again. Teri Paeschke Des Plaines, IL
