How do I grow a garden with a Black Walnut tree nearby?

My neighbor has a black walnut tree near my garden. I have built my garden up and added all new soils. I am still struggling with my garden producing as it should. Is there anything else I can do to help my garden grow with this awful tree nearby?

Black walnut toxicity can be a severe problem for vegetable gardening. Even with raised beds, the walnut roots can grow into the beds and upward to the surface. (Roots of the tree typically extend at least 3 to 4 times the spread of the tree's branches.) if you don't have space for a garden far from the tree, you may have to resort to growing plants in containers so the walnut roots can't come into contact with the vegetables. You could also create "containerized" raised beds by putting landscape fabric underneath the raised beds so that the walnut roots can't grow up into them. Soil depth of the raised beds should be at least a foot deep for most vegetables.

OR, rather than catering to the walnut tree with all that work and expensive material, we can just plant plants which are tolerant of the Black Walnuts' juglone; melons, corn, beans, squash, beets, carrots.... and a few others. Here is a useful link: http://www.extension.iastate.edu/news/2005/jul/070701.htm Of course, you could always go ahead and put down black mulch and continue to amend the soil, building it up, but why risk losing all your plants after putting in all the time and money?
