Vegetables and Juglone

So I'm new here, lets just get that out of the way. Anyway, I bought a house last summer and spent the last year preparing for my long awaited vegetable garden. I spent the entire winter on deciding what vegetables to grow, garden size, layout, soil needed, etc etc etc. I really thought I was being very complete on all of my preparation. The entire raised bed garden is now constructed and ready to roll and I've just made a horrible discovery that I have 5 black walnut trees that are about 60 feet from my garden. I am very anxious now about planting the plants that I have been working on all winter/spring. I am looking for the most complete list of plants that are affected and not affected by juglone. The frustrating part is that many internet searches turn up the same list of about 10 vegetables that are either able to co-exist with juglone, or are adversely affected by it. Where the heck is the list with the other 100+ vegetables. I know some of you people must have run your own experiments over the years. I was just looking for a list a little bigger than tomatoes, peppers, potatoes as being hurt by juglone. I'm getting very close to planting and need to determine what special precautions I may have to take. Just to be noted, I searched the forums briefly on here, but couldn't find a real cut and dry answer to my question. Thats all for now.....maybe I'll throw a pic of my garden on if anyone cares to see...it's my first run at this.

Sadly most all of what you will find on the subject is the same list.. which might or might not be correct. Columbine is listed as not tolerant, but I grow it very sucessfully under a black walnut. Tomatoes were actually used in the limited testing that has been done as a test for Juglone. Test subjects are potted with tomatoes in soil with or without Juglone.. just to make sure that Juglone is the cause of death or not. Black Walnut gardening is nothing short of frustrating. I am trying snap pea and pole beans this year.. just as an expriment. Sorry I can't be more helpfull.. but after years of searching I have found no clear cut answers at all on the subject. In the end we have more of less given up on vegetable near the walnut and have planted native fruit trees and shurbs.

Whoa, now you've really got me worried. I was under the impression from some local gardeners that you can definitely plant certain vegetables and they are completely unaffected by juglone. Your post somewhat implies that all vegetable gardening might be useless against this nasty foe. Please give me some hope and tell me that I can grow onions, beans, corn, radishes.....at least the things that the generic internet searched imply are unaffected.....anyone ever try broccoli in an an area with juglone? I hope that the decent distance and my raised bed on a higher part of the yard may help reduce the strength of it....this will certainly be a learning experience.

Oh, some plants are totally unaffected.. problem is the lists that I have seen don't mess with my expreinces. Columbine is on every single list as a no no.. but mine is fine. Beans are listed as inconclusive on the lists I have seen.. I am trying them this year for the first time. Broccoli is something that does thrive here under the best of condintions so I haven't tried it at all. I can give you a little hope with Corn.. while I haven't tried it.. I have seen lots of black walnuts next to Corn fields here, and have never really noticed any problem, althought I haven't been looking for one. My onions and radishes are all well away from my walnut, for not other reason then my wife choose to plant them on the other side of the yard. Juglone will be highest under the dripline.. and fall off as you get away from it, while their roots can go 50 more feet, I haven't had alot of problems beyond the dripline of mine.

TannedBack, I also have black walnuts on our proptery - 7 of them! Planting is like solving an intricate puzzle. If you have the patience to experiment, you might find some positive surprises (and some negative ones). Blackberries, for example, aren't suppoed to do well near a black walnut, but we found some growing beautifully when we cleared out an area. Our blueberries, however, were unhappy and we moved them. Yellow crookneck squash did fine, but zuchinni terribly. I use the lists as general guidelines and then try things out knowing I might lose some plants.

60 feet might be just enough away from your garden. Large old trees will have longer roots and more build up of juglone than smaller and younger trees.
